Interpret Pool Statistics

The pool statistics follow the process statistics for each node in a cluster system. To display only the pool statistics section of the Performance Evaluation Report, use the following qualifier:

/INCLUDE=POOL_STATISTICS

To disable the pool statistics display from the report, use this qualifier:

/INCLUDE=NOPOOL_STATISTICS

The following example shows the pool statistics of the Performance Evaluation Report:

The following statements are keyed to the columns in the previous example:

1. Large request packets
2. Intermediate request packets
3. Small request packets
4. Nonpaged pool (in bytes)
5. Number of locks
6. Number of named resources known by the Distributed Lock Manager

For OpenVMS Versions 6.0 and higher, the metrics for LRP, IRP, and SRP are obsolete. The following sample shows an example of this report:
