Cluster Instances Statistics and Details

Interpret the Cluster Instances window for instances of an Adaptive Server cluster configuration.

The Cluster Instances screen displays information pertaining to each cluster instance in graph and chart formats.

The Memory Usage chart represents the memory (physical and logical) and cache usage (procedure, statement and data) of a single cluster instance. The Processes chart gives a summary of running, blocking, and blocked processes on a single cluster instance.

The Device I/O per Sec graph represents the reads and writes of the selected instance during a certain time period. The Active Connections graph represents the number of user connections created on a selected instance during a certain time period. The Engine CPU Utilization graph represents the aggregate CPU utilization by all engines of a selected instance.

Right-click on a selected cache to use Resize to modify the size of the data cache, or Add Buffer Pool to change the configuration of your data cache buffer pool.
