The SYSVIEW metric MQ_QMGR_GetRate values are much lower than the GetRate values for the same queue manager on the MQROBJ display.
The MQROBJ display and the MQ_QMGR_GetRate metric are measuring rates at different intervals.
The MQROBJ display is showing the number of GETs per minute, whereas the MQ_QMGR_GetRate metric is measuring the number of GETs per second.
Additionally, all of the following metrics are measuring per second:
MQ_QMGR_GetRate
MQ_QMGR_PutRate
MQ_QUEU_GetRate
MQ_QUEU_PutRate
