the problem of getting data from multiple replicas under Kubernetes deployment controller and how to distinguish replica labels based on podname about jmx_exporter HOT 2 CLOSED

Should I use kubernetes_sd_configs to get data for each pod?

from jmx_exporter.

I have solved this problem by taking the data from kubernetes_sd_configs and taging the pod with JMX-Export enabled with a jmx=true tag. Here is an example of this in my Prometheus file

• job_name: 'kubernetes-jmx'
  kubernetes_sd_configs:
  • role: pod
    relabel_configs:
  • source_labels: [__meta_kubernetes_pod_label_jmx] # Matches only Pods that contain jmx tags
    regex: 'true' # The jmx tag value is true
    action: keep # Keep the matching Pod
  • source_labels: [address]
    regex: '([^:]+)(:\d+)?'
    replacement: '${1}:8081'
    target_label: address
    action: replace # The replacement port is 8081
  • action: labelmap
    regex: _meta_kubernetes_pod_label(.+)
  • source_labels: [__meta_kubernetes_namespace]
    action: replace
    target_label: kubernetes_namespace
  • source_labels: [__meta_kubernetes_pod_name]
    action: replace
    target_label: kubernetes_pod_name

from jmx_exporter.
