How to give our own labels in the serviceMonitorSelector field of the prometheus deployment

[ar-sumesh]

i tried giving my labels like app: myapp in the serviceMonitorSelector field but prometheus is not able to do discovery of targets , also not able to perform service discovery.
As i am not able to see the target and service discovery in the prometheus web page.

i done the modification in the prometheus.libsonnet , then complied them to get yaml files.

Also tell me how i can give these labels as commonLabels, so other components can also include this labels in their deployment.

There is no need to modify prometheus.libsonnet as everything can be done from main.jsonnet file.

To add labels in selector (bear in mind that ALL objects selected need to have ALL labels from serviceMonitorSelector to be picked up by prometheus server):

{
  prometheus+: {
    prometheus+: {
      spec+: {
        serviceMonitorSelector+: {
          app: "myapp",
        }
     }
  }
}

To add labels to commonLabels:

{
  values+:: {
    prometheus+: {
      commonLabels+: {
        label: "value",
      },
    },
  },
}
