Observe performance of buffer pools

Administrators with many systems need a single method of monitoring those systems, especially when they are complex as in data sharing groups.

A single observation provides you with a snapshot of current system behavior. Repeated observation keeps systems healthy by regularly checking for deviations from an expected level of performance.

These tasks require high-level summary information about critical buffer pool components and activities. The information should reflect a representative workload, and it should ideally be comparable with previous information. It should be easy to obtain and cause no significant load on the monitored system.

Current summary information should be collected and analyzed regularly.

You can use this information to detect out-of-line situations, to develop reference points for future comparisons, and to detect performance trends. Administrators can automate the collection of data by setting up scheduled batch jobs that collect specified performance data and create appropriate activity reports about buffer pools and group buffer pools. This ensures that up-to-date reports are always available for analysis.
