How to add Prometheus data source to Grafana?

[cyberfreakde]

When I try to add the Prometheus url http://localhost:9090/metrics to Grafana I get the error

Unknown error during query transaction. Please check JS console logs.

Am I missing something?

@cyberfreakde I don't have much experience with either of these but you should add it by prometheus' domain name. Since each app is a container, the "localhost" of each app is different.

Yeah, you likely don't want localhost you want the uuid of the installation as the hostname since that's what's exposed in the docker virtual network.

having the same problem currently, where can i find the containers UUID?

@Jan-Macenka I see you worked that out:

@Jan-Macenka said in Prometheus + Grafana actually working:

just had the same issue and wanted to add something here as a documentation:

If both Grafana and Prometheus are running as a cloudron-app, you can add Prometheus as a data-source in Grafana by inputting http://<PROMETHEUS-SERVICE-UUID>:9090 in the URL-field where PROMETHEUS-SERVICE-UUID can be found form the prometheus container either by looking up its installation location in the Storage-Tab or by connecting via terminal and copying the hostname.

Cheers,
