oc adm diagnostics all ā€” Diagnose common cluster problems

Synopsis

oc adm diagnostics all [Options]

Description

This utility helps troubleshoot and diagnose known problems for an OpenShift cluster and/or local host. This subcommand exists to run all available diagnostics:

oc adm diagnostics all

Available diagnostics vary based on client config and local OpenShift host config. All flags from the base command work similarly here, but all possible flags for individual diagnostics are also available.
