Pod - Metrics

Get current usage (cpu, memory) for all running pods in the current namespace. Use --all-namespaces and --no-headers as needed.


$ oc get PODMetrics
NAME                                           CPU    MEMORY WINDOW
api-newops-data-76b4c9dfcc-79jqc               0      424772Ki 5m0s

Pods Not Running

Use -ns NAMESPACE if needed. .status.phase is usually “Running” or “Succeeded”. You can filter one or both out. File:


#!/usr/bin/env bash

TIMESTAMP=$(date +"%Y%m%d-%H%M%S")
OFILE=PodsAllNamespaces.$TIMESTAMP.json
printf "Output in %s.\n" "$OFILE"
oc get pods --all-namespaces -o json |
    jq '.items[] | select(.status.phase != "Running") | {"name": .metadata.name, "namespace": .metadata.namespace, "phase": .status.phase , "containerState": .status.containerStatuses[]?.state}' > "$OFILE"

Output:


 $  head -40 PodsAllNamespaces.20230524-095113.json

  "name": "export-images-for-vmsr-28081680--1-45sl4",

    }
  }
