Can a pod monitor be configured with multiple fetches?

Yes, a pod monitor can be configured with multiple fetches. In the context of Kubernetes and monitoring tools like Prometheus, a pod monitor is used to specify the pods to be monitored and how to collect metrics from them.

Configuring a pod monitor with multiple fetches allows you to collect metrics from different endpoints or services running within the same pod. This can be useful when a pod hosts multiple containers or services, each exposing its own set of metrics.

For example, consider a pod that runs two containers: one for a web application and another for a background task processor. Each container might expose metrics on different ports. By configuring a pod monitor with multiple fetches, you can specify the endpoints for both containers, ensuring that metrics from both are collected and monitored.

Here's an example configuration snippet for a pod monitor with multiple fetches using Prometheus Operator:

apiVersion: monitoring.coreos.com/v1
kind: PodMonitor
metadata:
  name: example-pod-monitor
spec:
  selector:
    matchLabels:
      app: example-app
  endpoints:
  - port: web-metrics
    interval: 30s
    path: /metrics
  - port: task-metrics
    interval: 30s
    path: /task-metrics

In this example, the pod monitor targets pods labeled with app: example-app and fetches metrics from two different ports: web-metrics and task-metrics.
