|

Use this task to validate that some daemon perf counters were
|
|
incremented by the nested tasks.
|
|
|
|
Config:
|
|
'cluster_name': optional, specify which cluster
|
|
'target': dictionary of daemon type to list of performance counters.
|
|
'dry_run': just log the value of the counters, don't fail if they
|
|
aren't nonzero.
|
|
|
|
Success condition is that for all of the named counters, at least
|
|
one of the daemons of that type has the counter nonzero.

Example to check cephfs dirfrag splits are happening:
