=item B<--warning>
If failed Nodes, stopped Resources detected or Standby Nodes sends Warning instead of Critical (default)
as long as there are no other errors and there is Quorum.
=item B<--standbyignore>
Ignore any node(s) in standby, by default return threshold choosen.
=item B<--resources>
If resources not started on the node specified, send a warning message:
(format: <rsc_name>:<node>,<rsc_name>:<node>,...)
=item B<--ignore-stopped-clone>
Stopped clone resource on nodes (that match) are skipped.
=item B<--ignore-failed-actions>
Failed actions errors (that match) are skipped.
