## Introduction
`adsb-ultrafeeder` is a ADS-B data collector container that can be used to:
- retrieve ADS-B data from your SDR or other device
- display it on a local map, including options to show tracks, heatmaps, and system performance graphs
- forward the data to one or more aggregators using BEAST/BEAST-REDUCE/BEAST-REDUCE-PLUS format
- send MLAT data to these aggregators
- receive and consolidate MLAT results data (built-in `mlathub`)
- Interface with external visualization tools such as Grafana using statistics data available in InfluxDB and Prometheus format
In order to accomplish this, the container makes use of the following underlying technologies:
- SDR-Enthusiasts [Docker Base-Image](https://github.com/sdr-enthusiasts/docker-baseimage)
- [Wiedehopf's branch of `readsb`](https://github.com/wiedehopf/readsb)
- Wiedehopf's [tar1090](https://github.com/wiedehopf/tar1090) graphical interface
- Wiedehopf's [graphs1090](https://github.com/wiedehopf/graphs1090)
- [MLAT Client](https://github.com/adsbxchange/mlat-client.git)
It builds and runs on `linux/amd64`, `linux/arm/v7 (linux/armhf)` and `linux/arm64` architectures.
## Up-and-Running Quickly with `docker-compose`
- An example [`docker-compose.yml`](docker-compose.yml) file can be found in this repository.
- The accompanying environment variable values are defined in the [`.env`](.env) file in this repository
Once you have [installed Docker](https://github.com/sdr-enthusiasts/docker-install), you can follow these lines of code to get up and running in very little time:
```bash
sudo mkdir -p -m 777 /opt/adsb
cd /opt/adsb
wget https://raw.githubusercontent.com/sdr-enthusiasts/docker-adsb-ultrafeeder/main/docker-compose.yml
wget https://raw.githubusercontent.com/sdr-enthusiasts/docker-adsb-ultrafeeder/main/.env
```
Then edit the `docker-compose.yml` and `.env` files and make any changes as needed. Please configure ALL variables in `.env`:
```bash
nano docker-compose.yml
nano .env
```
Finally, bring up the stack. This may take a minute as it will automatically download the container and start it up:
```bash
docker compose up -d
```
## Ports
Some common ports are as follows (which may or may not be in use depending on your configuration). You can override the port mappings with the parameters shown in the [Optional Networking Parameters section](#optional-networking-parameters).
The general principle behind the port numbering, is:
- `30xxx` ports are connected to the main instance `readsb` that decodes and processes the SDR data
- `31xxx` ports are connected to the MLAT Hub
- `92xx` ports are for Prometheus statistics output
- `80` contains the Tar1090 web interface
| Port | Details |
| --------------------------- | -------------------------------------------------- |
| `30001/tcp` | Raw protocol input |
| `30002/tcp` | Raw protocol output |
| `30003/tcp` | SBS/Basestation protocol output |
| `32006/tcp` | SBS/Basestation protocol input |
| `30004/tcp`
`30104/tcp` | Beast protocol input |
| `30005/tcp` | Beast protocol output |
| `30006/tcp` | Beast reduce protocol output |
| `30047/tcp` | Json position output |
| `31003/tcp` | MLATHUB SBS/Basestation protocol output |
| `31004/tcp` | MLATHUB Beast protocol input |
| `31005/tcp` | MLATHUB Beast protocol output |
| `31006/tcp` | MLATHUB Beast-reduce protocol output |
| `9273/tcp` | Prometheus web interface with data from `readsb` |
| `9274/tcp` | Prometheus web interface with data from `Telegraf` |
| `80/tcp` | Tar1090 (map) web interface |
Any of these ports can be made available to the host system by using the `ports:` directive in your `docker-compose.yml`. The container's web interface is rendered to port `80` in the container. This can me mapped to a port on the host using the docker-compose `ports` directive. In the example [`docker-compose.yml`](docker-compose.yml) file, the container's Tar1090 interface is mapped to `8080` on the host system, and ports `9273-9274` are exposed as-is:
```yaml
ports:
- 8080:80 # to expose the web interface
- 9273-9274:9273-9274 # to expose the statistics interface to Prometheus
```
Json position output:
- outputs an aircraft object for every new position received for an aircraft if the --json-trace-interval has elapsed for that aircraft
- to make it output every received position, set READSB_JSON_TRACE_INTERVAL to 0.1
- each json object will be on a new line
-
Aircraft.json:
-
- available on the same port as the web interface, example: `http://192.168.x.yy:8087/data/aircraft.json`
## Runtime Environment Variables
The sections below describe how to configure each part of the container functionality. Each section describes what's needed to come up with a minimally viable configuration, followed by additional / optional parameters that can also be set.
Note:
- to enable a parameter, you can set it to any of `1`, `true`, `on`, `enabled`, `enable`, `yes`, or `y`. In the table below, we'll simply use `true` for convenience.
- to disable a parameter, you can set it to anything else or simply leave it undefined.
### General Configuration
You need to make sure that the USB device can be accessed by the container. The best way to do so, is by adding the following to your `docker-compose.yml` file:
```yaml
device_cgroup_rules:
- 'c 189:* rwm'
...
volumes:
- /dev:/dev:ro
```
The advantage of doing this (over simply adding a `device:` directive pointing at the USB port) is that the construction above will automatically recover if you "hot plug" your dongle. ⚠️This feature requires a recent version of docker-compose (version >=2.3). Make sure your system is up to date if dongles are not found. ⚠️
#### Basic Ultrafeeder Parameters
##### Mandatory Parameters
The following parameters must be set (mandatory) for the container to function:
| Environment Variable | Purpose | Default |

### Getting ADSB data to the Ultrafeeder
There are two ways to provide ADSB data to the Ultrafeeder:
- provide the container with access to a SDR or other hardware device that collects ADSB data
- allow the container to connect to a ADSB data source in Beast, Raw, or SBS format
These methods are not mutually exclusive - you can use both at the same time if you want.
#### Connecting to a SDR or other hardware device
If you want to connect your SDR to the container, here's how to do that:
##### Mandatory parameters
| Variable | Description | Controls which `readsb` option | Default |
| ---------------------- | ------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------ | -------------- |
| `READSB_DEVICE_TYPE` | If using an SDR, set this to `rtlsdr`, `modesbeast`, `gnshulc` depending on the model of your SDR. If not using an SDR, leave un-set. | `--device-type=` | Unset |
| `READSB_RTLSDR_DEVICE` | Select device by serial number. | `--device=` | Unset |
| `READSB_BEAST_SERIAL` | only when type `modesbeast` or `gnshulc` is used: Path to Beast serial device. | `--beast-serial=` | `/dev/ttyUSB0` |
##### Optional/Additional Parameters
| Variable | Description | Controls which `readsb` option | Default |
| ------------------- | ------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------ | -------- |
| `READSB_GAIN` | Set gain (in dB). Use `autogain` to have the container determine an appropriate gain, more on this below. | `--gain=` | Max gain |
| `READSB_RTLSDR_PPM` | Set oscillator frequency correction in PPM. See [Estimating PPM](https://github.com/sdr-enthusiasts/docker-readsb-protobuf/#estimating-ppm) | `--ppm=` | Unset |
##### AutoGain for RTLSDR Devices
If you have set `READSB_GAIN=autogain`, then the system will take signal strength measurements to determine the optimal gain. The AutoGain functionality is based on a (slightly) modified version of [Wiedehopf's AutoGain](https://github.com/wiedehopf/autogain). AutoGain will only work with `rtlsdr` style receivers.
Note that AutoGain is not related to the SDR's AGC setting (controlled with the `READSB_RTLSDR_ENABLE_AGC` variable). We do not recommend enabling AGC for Ultrafeeder or any other ADS-B decoder.
There are 2 distinct periods in which the container will attempt to figure out the gain:
- The initial period of 2 hours, in which an adjustment is done every 5 minutes
- The subsequent period, in which an adjustment is done once every day
Please note that in order for the initial period to complete, the container must run for 90 minutes without restarting.
When taking measurements, if the percentage of "strong signals" (i.e., ADSB messages with RSSI > 3 dB) is larger than 6%, AutoGain will reduce the receiver's gain by 1 setting. Similarly, if the percentage of strong signals is smaller than 2.5%, AutoGain will increment the receiver's gain by 1 setting. When AutoGain changes the gain value, the `readsb` component of the container will restart. This may show as a disconnect / reconnected in container logs.
We recommend running the initial period during times when there are a lot of planes overhead, so the system will get a good initial view of what signals look like when traffic is at its peak for your location. If you forgot to do this for any reason, feel free to give the AutoGain reset command (see below) during flights busy hour.
Although not recommended, you can change the measurement intervals and low/high cutoffs with these parameters:
| Environment Variable | Purpose | Default |
| ------------------------------------- | ------------------------------------------------------------------------------------------------------------- | ------- |
| `READSB_AUTOGAIN_INITIAL_TIMEPERIOD` | How long the Initial Time Period should last (in seconds) | `7200` |
| `READSB_AUTOGAIN_INITIAL_INTERVAL` | The measurement interval to optimize gain during the initial period of 90 minutes (in seconds) | `300` |
| `READSB_AUTOGAIN_SUBSEQUENT_INTERVAL` | The measurement interval to optimize gain during the subsequent period (in seconds) | `86400` |
| `READSB_AUTOGAIN_LOW_PCT` | If the percentage of "strong signals" (stronger than 3dBFS RSSI) is below this number, gain will be increased | `2.5` |
| `READSB_AUTOGAIN_HIGH_PCT` | If the percentage of "strong signals" (stronger than 3dBFS RSSI) is above this number, gain will be decreased | `6.0` |
If you need to reset AutoGain and start over determining the gain, you can do so with this command:
```bash
docker exec -it ultrafeeder /usr/local/bin/autogain1090 reset
```
#### Connecting to external ADSB data sources
In addition to (or instead of) connecting to a SDR or hardware device to get ADSB data, the container also supports ingesting or sending data from a TCP port. Here are some parameters that you need to configure if you want to make this happen:
##### All-in-One Configuration using `ULTRAFEEDER_CONFIG`
`ULTRAFEEDER_CONFIG` is a new parameter that can be used instead of separately defining `READSB_NET_CONNECTOR`, `MLAT_NET_CONNECTOR`, `MLATHUB_NET_CONNECTOR`/`MLATHUB_CONFIG`. These legacy parameters will still work; however, we wanted to provide a single parameter that enables configuration of incoming and outgoing ADSB data, MLAT-client data, and MLATHUB data.
Note that `ULTRAFEEDER_CONFIG` and `ULTRAFEEDER_NET_CONNECTOR` can be used interchangeably; in this documentation, we'll use `ULTRAFEEDER_CONFIG` as an example.
`ULTRAFEEDER_CONFIG` syntax:
The ULTRAFEEDER_CONFIG parameter can have multiple config strings, separated by a `;`. Please note that the config strings cannot contain `;` or `,` -- undefined things may happen if these characters are present.
```yaml
- ULTRAFEEDER_CONFIG=adsb,host,port,protocol[,uuid=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX][,extra-arguments]
...or...
- ULTRAFEEDER_CONFIG=mlat,host,port[,return_port][,uuid=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX][,extra-arguments]
...or to retrieve MLAT data from a remote receiver...
- ULTRAFEEDER_CONFIG=mlat,host,port[,return_port][,uuid=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX][,input_connect=remote-host:port,lat=xx.xxxx,lon=yy.yyyy,alt=zzz][,extra-arguments]
...or...
- ULTRAFEEDER_CONFIG=mlathub,host,port,protocol[,uuid=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX][,extra-arguments]
```
- To connect to an external ADSB (for input or output), UAT, or MLAT results source, use `- ULTRAFEEDER_CONFIG=adsb,host,port,protocol[,uuid=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX][,extra-arguments]`
- To connect and send data to an MLAT Server, use `- ULTRAFEEDER_CONFIG=mlat,host,port[,return_port][,uuid=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX][,name=Friendly_Name-123][,input_connect=remote-host:port,lat=xx.xxxx,lon=yy.yyyy,alt=zzz][,extra-arguments]`. For the optional parts in this structure, see [MLAT configuration](#mlat-configuration). Note - any MLAT results data received from the MLAT Server will automatically be aggregated in an [MLAT Hub](#configuring-the-built-in-mlat-hub) and shared with `tar1090`
- To add MLAT results from additional MLAT Servers not configured with Ultrafeeder (for example, MLAT results from FlightRadar24 or FlightAware/piaware), use `- ULTRAFEEDER_CONFIG=mlathub,host,port,protocol[,uuid=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX][,extra-arguments]`. You can further configure this MLAT Hub as described in the section [Configuring the built-in MLAT Hub](#configuring-the-built-in-mlat-hub)
In the above configuration strings:
- `host` is an IP address. Specify an IP/hostname/containername for incoming or outgoing connections.
- `port` and `return_port` are TCP port numbers
- `protocol` can be one of the following:
- `beast_reduce_out`: Beast-format output with lower data throughput (saves bandwidth and CPU)
- `beast_reduce_plus_out`: Beast-format output with extra data (UUID). This is the preferred format when feeding the "new" aggregator services
- `beast_out`: Beast-format output
- `beast_in`: Beast-format input
- `raw_out`: Raw output
- `raw_in`: Raw input
- `sbs_out`: SBS-format output
- `vrs_out`: SBS-format output
- `uat_in`: "special" RAW format input as generated by the `dump978` container on port 30978. It is advisable to use this protocol and port to get UAT data from dump978, for example: `- ULTRAFEEDER_CONFIG=adsb,dump978,30978,uat_in`
- `uuid` is a Universally Unique Identifier. You can reuse the one you generated for AdsbExchange, or you can generate a new one with this Linux command: `cat /proc/sys/kernel/random/uuid`. If omitted, it will use the `UUID` environment parameter, or if that one doesn't exist, it will leave the field empty.
- `name` is a friendly name (containing any character of the set \[A-Za-z0-9_-\]) that will be sent to the MLAT Server, used to identify the station by name. If omitted, it will use the `MLAT_USER` parameter, or if that one doesn't exist, it will leave the field empty.
##### Networking parameters
| Environment Variable | Purpose | Default |
| -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------- |
| `BEASTHOST` | IP/Hostname of a Mode-S/Beast provider (`dump1090`/`readsb`) | |
| `BEASTPORT` | TCP port number of Mode-S/Beast provider (`dump1090`/`readsb`) | `30005` |
| `MLATHOST` | Legacy parameter. IP/Hostname of an MLAT provider (`mlat-client`). Note - using this parameter will not make the MLAT data part of the consolidated mlathub. The preferred way of ingesting MLAT results is using the `mlathub` functionality of the container, see below for details | |
| `MLATPORT` | Legacy parameter used with `MLATHOST`. TCP port number of an MLAT provider (`mlat-client`) | 30105 |
##### Feeding directly from Ultrafeeder
There are several aggregators, both non-profit and commercial, that can directly be sent data from ultrafeeder without the need for an additional feeder container. We have added them in the example `docker-compose.yml` snippet above. Here is a partial list of these aggregators. All of them use the `beast_reduce_plus` format for feeding ADSB data, and `mlat-client` for feeding MLAT:
| Name | (C)ommercial/
(N)on-profit | Description | Feed details |
| --------------- | ------------------------------ | --------------------------------------------------------- | ------------------------------------------------------------------------------------------ |
| Airplanes.live | N | Run by volunteers that used to be related to adsbexchange | adsb:`feed.airplanes.live` port `30004`
mlat: `feed.airplanes.live` port `31090` |
| ADSB.fi | N | Run by a private individual located in Finland.
No longer associated with any former members of adsbexchange. | adsb:`feed.adsb.fi` port `30004`
mlat: `feed.adsb.fi` port `31090` |
| ADSB.lol | N | Run by a private individual located in the Netherlands | adsb:`in.adsb.lol` port `30004`
mlat: `in.adsb.lol` port `31090` |
| Planespotters | N | planespotters.net | adsb:`feed.planespotters.net` port `30004`
mlat: `mlat.planespotters.net` port `31090` |
| The Air Traffic | N | Run by a private individual | adsb:`feed.theairtraffic.com` port `30004`
mlat: `mlat.theairtraffic.com` port `31090` |
| AVDelphi | N | Aviation data-science company (non-profit) | adsb:`data.avdelphi.com` port `24999`
mlat: no MLAT |
| ADSB Exchange | C | Large aggregator owned by JetNet | adsb:`feed1.adsbexchange.com` port `30004`
mlat: `feed.adsbexchange.com` port `31090` |
| RadarPlane | N | Run by a few volunteers in Canada and Portugal | adsb: `feed.radarplane.com` port `30001`
mlat: `feed.radarplane.com` port `31090` |
| Fly Italy ADSB | N | Run by a few ADSB enthusiasts in Italy | adsb: `dati.flyitalyadsb.com` port `4905`
mlat: `dati.flyitalyadsb.com` port `30100` |
When feeding AdsbExchange, Ultrafeeder will send statistics to adsbexchange.com by default. See the description of the `ADSBX_STATS` parameter on how to disable this.
##### Alternate Configuration Method with `READSB_NET_CONNECTOR`
Instead of (or in addition to) using `BEASTHOST`, you can also define ADSB data ingests using the `READSB_NET_CONNECTOR` parameter. This is the preferred way if you have multiple sources or destinations for your ADSB data. This variable allows you to configure incoming and outgoing connections. The variable takes a semicolon (`;`) separated list of `host,port,protocol[,uuid=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX]`, see the section [All-in-One Configuration using `ULTRAFEEDER_CONFIG`](#all-in-one-configuration-using-ultrafeeder_config) for explanation of these parameters.
NOTE: If you have a UAT dongle and use `dump978` to decode this, you should use `READSB_NET_CONNECTOR` to ingest UAT data from `dump978`. See example below
```yaml
environment:
...
- READSB_NET_CONNECTOR=dump978,30978,uat_in;...
...
```
#### Optional Networking Parameters
There are many optional parameters relating to the ingestion of data and the general networking functioning of the `readsb` program that implements this functionality.

#### MLAT configuration
The Ultrafeeder contains a capability to send MLAT data to MLAT servers to be processed, and to receive the MLAT results and integrate those with an MLAT Hub and the `tar1090` map.
It will create a separate instance of `mlat-client` for each defined MLAT server. The parameters for these `mlat-client` instances is as follows:
```yaml
environment:
...
- ULTRAFEEDERCONFIG=
...
mlat,mlat-server1.com,port1,return_port1,uuid=1234-5678-90123,inputconnect=remote_receiver1:30005,lat=12.3456,lon=45.6789,alt=18m,--arg1 hello --arg2 world;
mlat,mlat-server2.com,port2,return_port2,uuid=5678-9012-34567,inputconnect=remote_receiver2:30005,-lat=12.3456,lon=45.6789,alt=18m,--arg1 hello-again --arg2 universe
...
- MLAT_USER=some_friendly_user_name
```
where:
| Parameter | Mandatory/Optional | Description |
| ----------------- | ------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `mlat` | Mandatory | indicates that the line container MLAT-client configuration parameters |
| `mlat-server.com` | Mandatory | the domain name or ip address of the target MLAT server |
| `port` | Mandatory | the port (TCP or UDP) of the target MLAT server |
| `return_port` | Optional | the port at which the MLAT results are made available in BEAST format. We recommend to sequentially number them starting at 39000 |
| `uuid` | Optional | a unique user ID for this MLAT server instance. If included, the string must start with `uuid=`. If not included, it will use the value of the `UUID` parameter if it exists |
| `input_connect` | Optional | a unique input connection in the form `input_connect=remotehost:port`, where `remotehost:` is the hostname or IP address and TCP port of your remote BEAST source. This can be used to connect to a remote Beast source and forward MLAT data to an MLAT server |
| `lat` | Optional | the latitude to be sent to the MLAT server in the form `lat=xx.xxxxx`. If omitted, the `LAT` / `READSB_LAT` parameter will be used. This is meant to be used in combination with `input_connect` for connecting to a remote Beast source and forward MLAT data to an MLAT server |
| `lon` | Optional | the longitude to be sent to the MLAT server in the form `lon=xx.xxxxx`. If omitted, the `LONG` / `READSB_LON` parameter will be used. This is meant to be used in combination with `input_connect` for connecting to a remote Beast source and forward MLAT data to an MLAT server |
| `alt` | Optional | the altitude to be sent to the MLAT server in the form `alt=xx.xxxxx`. If omitted, the `ALT` / `READSB_ALT` parameter will be used. This is meant to be used in combination with `input_connect` for connecting to a remote Beast source and forward MLAT data to an MLAT server |
| `extra-arguments` | Optional | Any extra parameter you want to pass to the `mlat-client` program. Will be added verbatim to the command line |
Note - the optional parameters can be given in any order.
The `MLAT_USER` parameter is passed to the MLAT Client and server, and will show up as a "friendly" name on MLAT related stats at your MLAT aggregator.
#### Configuring the built-in MLAT Hub
An "MLAT Hub" is an aggregator of MLAT results from several sources. Since the container is capable of sending MLAT data to multiple ADSB aggregators (like adsb.lol/fi/one, etc), we built in a capability to:
- collect the MLAT results from all of these services
- ingest MLAT results from other containers (FlightAware, Radarbox, etc.)
- make the consolidated MLAT results available on a port in Beast or SBS (BaseStation) format
- create outbound connections using any supported format to send your Beast data wherever you want
Note - due to design limitations of `readsb`, the `tar1090` graphical interface will by default ONLY show MLAT results from the aggregators/MLAT sources that were defined with the `MLAT_NET_CONNECTOR` parameter. If you want to show any additional MLAT results (for example, those from `piaware`), you should add a separate `READSB_NET_CONNECTOR` for them. Adding these sources only to `MLATHUB_NET_CONNECTOR` will make the data available on the MLATHUB, but won't display them on your `tar1090` map.
Generally, there is little to configure, but there are a few parameters that you can set or change:
| Variable | Description | Default if omitted |
| ------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------ |
| `MLATHUB_SBS_OUT_PORT` | TCP port where the consolidated MLAT results will be available in SBS (BaseStation) format | `31003` |
| `MLATHUB_BEAST_IN_PORT` | TCP port you where you can send additional MLAT results to, in Beast format | `31004` |
| `MLATHUB_BEAST_OUT_PORT` | TCP port where consolidated MLAT results will be available in Beast format | `31005` |
| `MLATHUB_BEAST_REDUCE_OUT_PORT` | TCP port where consolidated MLAT results will be available in Beast format with reduced data rates | `31006` |
| `MLATHUB_NET_CONNECTOR` | List of semi-colon (`;`) separated IP or host, port, and protocols where MLATHUB will connect to ingest or send MLAT data. It follows the same syntax as described in the [`READSB_NET_CONNECTOR` syntax section](#alternate-configuration-method-with-readsb_net_connector) above | Unset |
| `MLATHUB_DISABLE` | If set to `true`, the MLATHUB will be disabled even if there are `mlat-client`s running in the container | Unset |
### Web Gui (`tar1090`) Configuration
The Container creates an interactive web interface displaying the aircraft, based on Wiedehopf's widely used [tar1090](https://github.com/wiedehopf/tar1090) software.
The web interface is rendered to port `80` in the container. This can me mapped to a port on the host using the docker-compose `ports` directive.
All of the variables below are optional.
Note - due to design limitations of `readsb`, the `tar1090` graphical interface will by default ONLY show MLAT results from the aggregators/MLAT sources that were defined with the `MLAT_NET_CONNECTOR` parameter. If you want to show any additional MLAT results (for example, those from `piaware`), you should add a separate `READSB_NET_CONNECTOR` entry for them.

#### Enabling UAT data
ADS-B over UAT data is transmitted in the 978 MHz band, and this is used in the USA only. To display the corresponding graphs, you should:
1. Set the following environment parameters:
```yaml
- URL_978=http://dump978/skyaware978
```
2. Install the [`docker-dump978` container](https://github.com/sdr-enthusiasts/docker-dump978). Note - only containers downloaded/deployed on/after Feb 8, 2023 will work.
Note that you **must** configure `URL_978` to point at a working skyaware978 website with `aircraft.json` data feed. This means that the URL `http://dump978/skyaware978/data/aircraft.json` must return valid JSON data to this `tar1090` container.
#### Enabling AirSpy graphs
Users of AirSpy devices can enable extra `graphs1090` graphs by configuring the following:
- Set the following environment parameter:
```yaml
- ENABLE_AIRSPY=yes
```
- To provide the container access to the AirSpy statistics, map a volume in your `docker-compose.yml` file as follows:
```yaml
volumes:
- /run/airspy_adsb:/run/airspy_adsb
...
```
#### Enabling Disk IO and IOPS data
To allow the container access to the Disk IO data, you should map the following volume:
```yaml
volumes:
- /proc/diskstats:/proc/diskstats:ro
...
```
#### Configuring the Core Temperature graphs
By default, the system will use the temperature available at Thermal Zone 0. This generally works well on Raspberry Pi devices, and no additional changes are needed.
On different devices, the Core Temperature is mapped to a different Thermal Zone. To ensure the Core Temperature graph works, follow these steps
First check out which Thermal Zone contains the temperature you want to monitor. On your host system, do this:
```bash
for i in /sys/class/thermal/thermal_zone* ; do echo "$i - $(cat ${i}/type) - $(cat ${i}/temp 2>/dev/null)"; done
```
Something similar to this will be show:
```bash
/sys/class/thermal/thermal_zone0 - acpitz - 25000
/sys/class/thermal/thermal_zone1 - INT3400 Thermal - 20000
/sys/class/thermal/thermal_zone2 - TSKN - 43050
/sys/class/thermal/thermal_zone3 - NGFF - 32050
/sys/class/thermal/thermal_zone4 - TMEM - 39050
/sys/class/thermal/thermal_zone5 - pch_skylake - 40500
/sys/class/thermal/thermal_zone6 - B0D4 - 54050
/sys/class/thermal/thermal_zone7 - iwlwifi_1 -
/sys/class/thermal/thermal_zone8 - x86_pkg_temp - 57000
```
Repeat this a few times to ensure that the temperature varies and isn't hardcoded to a value. In our case, either Thermal Zone 5 (`pch_skylake` is the Intel Core name) or Thermal Zone 8 (the temp of the entire SOC package) can be used. Once you have determined which Thermal Zone number you want to use, map it to a volume like this. Make sure that the part to the left of the first `:` reflects your Thermal Zone directory; the part to the right of the first `:` should always be `/sys/class/thermal/thermal_zone0:ro`.
Note that you will have to add `- privileged: true` capabilities to the container. This is less than ideal as it will give the container access to all of your system devices and processes. Make sure you feel comfortable with this before you do this.
```yaml
privileged: true
volumes:
- /sys/class/thermal/thermal_zone8:/sys/class/thermal/thermal_zone0:ro
...
```
Note - on some systems (DietPi comes to mind), `/sys/class/thermal/` may not be available.
#### Reducing Disk IO for Graphs1090
Note - _this feature is still somewhat experimental. If you are really attached to your statistics/graphs1090 data, please make sure to back up your mapped drives regularly_
If you are using a Raspberry Pi or another type of computer with an SD card, you may already be aware that these SD cards have a limited number of write-cycles that will determine their lifespan. In other words - a common reason for SD card failure is excessive writes to it.
By the nature of having to log lots of data the `graphs1090` functionality writes a lot to the SD card. To reduce the number of write cycles, there are a few parameters you can set.
Enabling this functionality will cause `graphs1090` to temporarily write all data to volatile memory (`/run`) instead of persistent disk space (`/var/lib/collectd`). This data is backed up to persistent disk space in regular intervals and upon (graceful) shutdown of the container.
Note -- there is a chance that the data isn't written back in time (due to power failures, non-graceful container shutdowns, etc), in which case you may lose statistics data that has been generated since the last write-back.
The feature assumes that you have mapped `/var/lib/collectd` to a volume (to ensure data is persistent across container recreations), and `/run` as a `tmpfs` RAM disk, as shown below and also as per the [`docker-compose.yml` example](docker-compose.yml):
```yaml
volumes:
- /opt/adsb/ultrafeeder/globe_history:/var/globe_history
...
tmpfs:
- /run:exec,size=256M
...
```
| Environment Variable | Purpose | Default |
| --------------------------------- | ------------------------------------------------------------------------------------------- | ------- |
| `GRAPHS1090_REDUCE_IO=` | Optional Set to `true` to reduce the write cycles for `graphs1090` | Unset |
| `GRAPHS1090_REDUCE_IO_FLUSH_IVAL` | Interval (in secs) over which the `graphs1090` data is written back to non-volatile storage | `3600` |
### `timelapse1090` Configuration
Legacy: **We recommend AGAINST enabling this feature** as it has been replaced with . `timelapse1090` writes a lot of data to disk, which could shorten the lifespan of your Raspiberry Pi SD card. The replacement functionality is better and doesn't cause any additional disk writes.
| Environment Variable | Purpose | Default |
| ------------------------ | ------------------------------------------------------------------------------------------------------------------------------- | ------- |
| `ENABLE_TIMELAPSE1090` | Optional / Legacy. Set to `true` to enable timelapse1090. Once enabled, can be accessed via | Unset |
| `TIMELAPSE1090_INTERVAL` | Snapshot interval in seconds | `10` |
| `TIMELAPSE1090_HISTORY` | Time saved in hours | `24` |
## Web Pages
If you have configured the container as described above, you should be able to browse to the following web pages:
You should now be able to browse to:
- to access the tar1090 web interface.
- to see a replay of past data
- to see the heatmap for the past 24 hours
- to see a different heatmap for the past 24 hours
- to see the tracks of all planes for the past 24 hours
- to see performance graphs
## Paths
No paths need to be mapped through to persistent storage. However, if you don't want to lose your range outline and aircraft tracks/history and heatmap / replay data on container restart, you can optionally map these paths:
| Path | Purpose |
| ------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------- |
| `/opt/adsb/ultrafeeder/globe_history:/var/globe_history` | Holds range outline data, heatmap / replay data and traces if enabled. |
| _Note: this data won't be automatically deleted, you will need to delete it eventually if you map this path._ |
| `/opt/adsb/ultrafeeder/timelapse1090:/var/timelapse1090` | Holds timelapse1090 data if enabled. (We recommend against enabling this feature, see above) |
| `/opt/adsb/ultrafeeder/collectd:/var/lib/collectd` | Holds graphs1090 & performance data |
| `/proc/diskstats:/proc/diskstats:ro` | Makes disk statistics available to `graphs1090` |

When using the `:telegraf` tag, the image contains [Telegraf](https://docs.influxdata.com/telegraf/), which can be used to capture metrics from `ultrafeeder` if an output is enabled.
See [README-grafana.md](README-grafana.md) for detailed instruction on how to configure this.
**NOTE - READ CAREFULLY**: As of 27 April 2023, the `latest` image no longer contains Telegraf. If you want to send metrics to InfluxDB or Prometheus, please use this image:
```yaml
services:
tar1090:
image: ghcr.io/sdr-enthusiasts/docker-tar1090:telegraf
...
```
### Configuring Grafana
Please see the [separate instruction document](README-grafana.md) for step by step instructions on how to set up and configure a Grafana Dashboard with Prometheus. The sections below are provided as a reference.
### Output from Ultrafeeder to Prometheus
In order for Telegraf to serve a [Prometheus](https://prometheus.io) endpoint, the following environment variables can be used:
| Variable | Description |
| ------------------- | ------------------------------------------------------------------------ |
| `PROMETHEUS_ENABLE` | Set to `true` for a Prometheus endpoint on `http://0.0.0.0:9273/metrics` |
### Output from Ultrafeeder to InfluxDBv2
In order for Telegraf to output metrics to an [InfluxDBv2](https://docs.influxdata.com/influxdb/) time-series database, the following environment variables can be used:
| Variable | Description |
| ------------------- | ----------------------------------- |
| `INFLUXDBV2_URL` | The URL of the InfluxDB instance |
| `INFLUXDBV2_TOKEN` | The token for authentication |
| `INFLUXDBV2_BUCKET` | Destination bucket to write into |
| `INFLUXDBV2_ORG` | InfluxDB Organization to write into |
## Message decoding introspection
You can look at individual messages and what information they contain, either for all or for an individual aircraft by hex:
```bash
# only for hex 3D3ED0
docker exec -it ultrafeeder /usr/local/bin/viewadsb --show-only 3D3ED0
# for all aircraft
docker exec -it ultrafeeder /usr/local/bin/viewadsb --no-interactive
# show position / CPR debugging for hex 3D3ED0
docker exec -it ultrafeeder /usr/local/bin/viewadsb --cpr-focus 3D3ED0
```
## Minimalist setup
If you want to use `ultrafeeder` _only_ as a SDR decoder but without any mapping or stats/graph websites, without MLAT connections or MLAT-hub, etc., for example to minimize CPU and RAM needs on a low CPU/memory single board computer, then do the following:
- in the `ULTRAFEEDER_CONFIG` parameter, remove any entry that starts with `mlat` or `mlathub`. This will prevent any `mlat-client`s or `mlathub` instances to be launched. If you still want to connect the `mlat-client`(s) to external MLAT servers but you don't want to run the overhead of a MLATHUB, you can leave any entries starting with `mlat` in the `ULTRAFEEDER_CONFIG` parameter, and set `MLATHUB_DISABLE=true`
- Set the parameter `TAR1090_DISABLE=true`. This will prevent the `nginx` webserver and any websites to be launched and no `collectd` (graphs1090) or `rrd` (ADSB message history) data to be collected or retained.
- Make sure to use `ghcr.io/sdr-enthusiasts/docker-adsb-ultrafeeder:latest` and specifically NOT the `ghcr.io/sdr-enthusiasts/docker-adsb-ultrafeeder:telegraf` label as Telegraf adds a LOT of resource use to the container
## Logging
All logs are to the container's stdout and can be viewed with `docker logs -t [-f] container`.
