Use the DB2 SRM BPM attributes to create situations to monitor buffer pool activity.
Allocated Pages The total number of pages allocated to the buffer pool: It includes pages that are currently read or updated, updated pages, and available pages.
Get Page Rate The number of get page operations per second over last interval.
Hiperpool Size The size of the hiperpool.
Interval Time The number of seconds since last sample.
Origin Node Name The node name of the DB2 system. Valid entry is an alphanumeric text string, with a maximum length of 32 characters.
Pages In Use The number of virtual buffer pool pages in use at the end of the interval (a snapshot value of the current number of non-stealable buffers): A non-stealable buffer is either one which has an outstanding Getpage (someone is currently looking at this page) or one which has been updated and not yet written out to DASD.
Prefetch Request Rate The number of prefetch requests issued per second over the last interval.
Read IO Rate The number of read I/O operations per second over the last interval.
Time The date and time, as set on the monitored system, indicating the instance when the agent collects information.
Utilization The percentage of the buffer pool currently in use: It is calculated as: (Pages In Use / Allocated Pages) * 100; the buffer pool may be too small if this is greater than 50%. The range of valid entries is from 0.0 to 100.0.
VP Size The size of the virtual buffer pool.
Write IO Rate The number of write I/Os performed per second over last interval.
