How to Set Prometheus to Report Flink Job Metrics of a Specific Deployment Target
Answer
All the Kubernetes Namespaces which the Flink Jobs are deployed must be set inside the Prometheus Operator values file:
prometheusOperator:
namespaces:
additional:
- vvp-jobs-new1
- vvp-jobs-new2
In addition to the above configuration, a Kubernetes Service definition to expose Flink Pod metrics and a Prometheus Operator ServiceMonitor to declare scraping configuration of that Service must be added for all Deployment Targets individually:
kubectl --namespace "vvp-jobs-new1" apply -f prometheus-operator-resources/service-monitor.yaml
kubectl --namespace "vvp-jobs-new2" apply -f prometheus-operator-resources/service-monitor.yaml
