DESCRIPTION

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

21       oc ex diagnostics all
22
23
24       Available  diagnostics  vary based on client config and local OpenShift
25       host config. All flags from the base command work similarly  here,  but
26       all possible flags for individual diagnostics are also available.
