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:
19 oc adm diagnostics all
22 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.
