## Advanced Configuration: support for dashboards for multiple ultrafeeder instances ### Making the feeder's heatmap and graphs pages available in Grafana
The dashboard comes preconfigured with panels that show the tar1090 heatmap and graphs1090 stats pages. These panels need to be configured to look for this data at the correct URL.
Note that these URLs need to be accessible from the browser that you use to see the Grafana dashboard - they should work if you enter them in your browser's URL box.
If you don't have access to these URLs, it'd be safe to simply delete these panels from your dashboard.
- Step a: Log into Grafana and open the Ultrafeeder dashboard that you already created

- Step e: Find all (2) instances of `my_feeder` and replace them with the IP of your tar1090 map page

### Advanced Configuration: support for dashboards for multiple ultrafeeder instances
If you have multiple feeder stations with multiple instances of `ultrafeeder`, you can configure a dashboard for each of them. Here's how. In our example, we have two `ultrafeeder` instance called `heerlen` and `trenton`. You can adjust these names in accordance with your needs.
