Buffer Pool Manager Metrics

Created:  | Updated: 


z/IRIS streams Buffer Pool Manager metrics per queue manager using data from IBM's SMF type 115, subtype 1 records. Each measurement is structured according to a schema that can be found in this document.

The Buffer Pool Manager measurements depict utilization of buffer pools and are grouped by their number (i.e. identifier) per MQ Queue Manager. Alternative grouping is possible using host name (z/OS LPAR name) or RMID.


Measurements

Measurements are prefixed. These prefixes can be changed via the z/IRIS IronTap server or container configuration.
