Log Manager Metrics
Created: | Updated:
z/IRIS streams MQ storage manager metrics using data from IBM's SMF type 115, subtype 1 records. Each Log Manager measurement is structured according to a schema that can be found in this document.
The Log Manager measurements record activity (read, writes and checkpoints) as well as compression failure events and are grouped by MQ Queue Manager. Alternative grouping is possible using host name (z/OS LPAR name) or RMID.
Measurements
zos.mq.log.rate
The value of log rate is computed as writes/seconds.
