ocadmtop

This script will collect the PODs' resources consumption and display them by node.

Usage

ocadmtop_node.sh [-c|-m|-p] [-A|-L <label1>,<label2>,...|-H <host1>,<host2>,...] [-d {0-10}] [-t <TIMEOUT>][-v|-h]
  -c: sort by CPU (default)
  -m: sort by Memory
  -n: filter on a specific namespace PODs
  -p: sort by namespace/pod
  -L: retrieve node(s) matching all labels
  -H: retrieve node(s) by hostname
  -A: retrieve All nodes (default)
  -C: Display the container details (default: false)
  -d: debug/loglevel mode. Provide additional 'oc --loglevel' ouput. (Recommended value: 6)
  -t: The length of time to wait before giving up on a single server request. Non-zero values should contain a
      corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests.
  -v: Display the version
  -h: Display this help
ocadmtop_node.sh - Version:  X.Y

Examples

• Displaying ALL nodes (default) sorted by CPU (default) with a timeout set to 2 minutes.

./ocadmtop_node.sh -t 2m

• Displaying all master nodes sorted by MEM

./ocadmtop_node.sh -L node-role.kubernetes.io/master -m

• Displaying some nodes sorted by POD

./ocadmtop_node.sh -H master-1.lab.example.com,master-2.lab.example.com -p

• Displaying a node sorted by CPU with loglevel 6

./ocadmtop_node.sh -H master-1.lab.example.com -d 6

• Displaying a specific namespace by MEM on all nodes

./ocadmtop_node.sh -n openshift-monitoring -m

• Displaying the worker nodes PODS and containers sorted by CPU

  ./ocadmtop_node.sh -c -L node-role.kubernetes.io/worker= -C
