oc-nodepp (nodes++)

A CLI plugin for OpenShift v4 which provides a more detailed view of the state of the cluster's nodes and machines.

This plugin originated from the perspective of an OpenShift administrator in order to provide an easier at-a-glance view of the cluster's state, where frequently the following commands are employed:

• oc get nodes
• oc get machines -n openshift-machine-api
• oc adm top nodes

This plugin provides a view that combinations information from all three sources:

• Nodes, and their CPU and memory resource usage.
• Machines associated with nodes, and their provisioning status.
• Highlights for:
  • Machines that do not have associated nodes.
  • Nodes that are NotReady, cordoned, or updating
  • CPU and memory resource usage that exceeds 85%

Usage

oc-nodepp will act as an OpenShift CLI plugin if available in the user's $PATH

# Search across all nodes in the cluster 
oc nodepp

# View a specific node 'node1'
oc nodepp node1

# Don't query for node metrics 
oc nodepp -u=false

# Don't show the symbol key output
oc nodepp -k=false
