[GitHub] [camel-k] mertdotcc opened a new issue, #4204: Prometheus trait auto discovery cross-namespace

mertdotcc opened a new issue, #4204:
URL: https://github.com/apache/camel-k/issues/4204

   Similar to [#4178](https://github.com/apache/camel-k/issues/4178) but for the `Prometheus` trait.
   
   Right now I work around this issue by using `Prometheus`' `podMonitorNamespaceSelector` and `podMonitorSelector` configs.
   
   Looks something like this:
   ```
   ...
   podMonitorNamespaceSelector:
     matchLabels:
       kubernetes.io/metadata.name: default (1)
   podMonitorSelector:
     matchExpressions:
     - key: camel.apache.org/integration (2)
       operator: Exists
   ...
   ```
   `(1) tells Prometheus to listen to the "default" namespace`
   `(2) checks for pods that have the label key .../integration`
   
   Chances are, most people have their `Prometheus` instance running in their `monitoring` namespace if they installed it using the official [Prometheus Operator](https://prometheus-operator.dev/) installation guide (or using [kube-prometheus](https://github.com/prometheus-operator/kube-prometheus) for that matter - same thing).
   
   The thing is people probably won't be running their integrations in the `monitoring` namespace. For whatever namespace they plan on running their integrations, they need to tell the `Prometheus` instance that information so it knows what to pull. We are not sending any data/metrics to `Prometheus` (assuming that [Pushgateway](https://github.com/prometheus/pushgateway) is not used) we are explicitly telling/configuring it to listen to label `X` or namespace `Y` since its all pull-based.
   
   Having the necessary options in the `Prometheus` [trait](https://camel.apache.org/camel-k/next/traits/prometheus.html) to handle these `podMonitorNamespaceSelector` and `podMonitorSelector` configs (and anything else for that matter - open to discussions) would be helpful for so many people IMHO.

   The trait is replaced by the Camel Monitor Operator: https://camel.apache.org/camel-k/next/observability/dashboard.html
