Monitoring SRM Software
Implementing the SRM software can introduce some interesting new challenges for performance monitoring and management.
The question is often asked “How do I determine that the SRM software is constraining a workload?”. The answer is simple. If the run queue is greater than the number of CPUs and the CPU is almost 100 percent busy (usr+sys>95 percent) then SRM is constraining a workload somewhere. This is no different from the standard Solaris scheduler since the SRM software allows a user to consume more than that user's share when there are spare CPU cycles available. The difference with the SRM software is which workloads are constrained, and that depends on how the shares are apportioned.
