Indeed. You can still set it down to 1min in the crontab if needed. But the point is to gather a better understanding on the dirties (and many other useful metrics) evolution during a long time frame. You will always loose a small part of information after a fencing. No matter if your period is 10min, 1min or even 1s. _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
