Re: Relationship between PRM output and sar output

PRM stands for Process Resource Manager. You create resource thresholds via xprm.

The command sar -u 5 5 reads the current consumption of resources, while PRM is the high water mark usually used to failover in a ServiceGuard cluster.

Note: Use to be a bug in PRM where you had to first max out your resource and failover first, before the PRM threshold went into place.
