Prometheus Plug-In: Also detect victoriametrics

[micw]

Hello,

I run victoriametrics in my stacks (as replacement of prometheus). It should provide the same information (at least with lens it does) but it's not detected by the plug-in.

Could detection of victoriametrics be added? What is the exact mechanism to check if prometheus is available in the cluster or not?

@yolossn Can you check this one?

[yolossn]

The plugin searches the cluster for pods with the app.kubernetes.io/name=prometheus label to identify the prometheus pod to query the metrics. can you check if your prometheus pod has this label?

kubectl get pods -l app.kubernetes.io/name=prometheus --all-namespace

We are working on making the prometheus url configurable so that the user can configure the prometheus endpoint to fetch the metrics from.

Just chiming in to say I've had a look into this, and it's not possible to overwrite that annotation if you're deploying VictoriaMetrics through the the VM operator, which is currently the recommended way to deploy VictoriaMetrics.

One option would be of extending this code to support the relevant VictoriaMetrics targets such as vmsingle and vmselect. Short-term this would work, but being able to set the query URL explicitly seems saner.
