Introduction
Below are metric specific to MQ on ZOS.
JMX MBean Tree
Mainframe Queue manager view of JMX Metric tree
QMGR_STATUS
ZOS hosted queue managers do not provide the same Queue Manager STATUS information found in other operating environments. Lamaxu creates a STATUS metric for consistency with the other platforms.
PAGESET_USAGE
More specific Pageset usage can be found on QUEUE_STATUS
Pageset Metrics also found under QUEUE_STATUS
On ZOS hosted queues, LAMAXU merges information relating to the underlying PAGESET usage, and also exposes a custom metric, PAGESET_PERCENT_USED, under the QUEUE_STATUS tree, making it easier to monitor and spot issues with PAGESET utilisation.

RESETQSTATS
Lamaxu exposes the most recent queue statistics for each queue as a JMX MBean under the RESETQSTATS tree for the queue manager.
On Mainframe (ZOS) systems, the statistics are obtained using a resetqstats command and will contain less detail than on non-ZOS systems.
The Statistics Interval for ZOS is the same as the Lamaxu Agent Refresh Interval.
