IBM WebSphere MQ Performance Counters

Queue Performance Counters

The following table describes the Queue Performance counters:

Measurement
Description
Event - Queue Depth High (events per second)
An event triggered when the queue depth reaches the configured maximum depth.
Event - Queue Depth Low (events per second)
An event triggered when the queue depth reaches the configured minimum depth.
Event - Queue Full (events per second)
An event triggered when an attempt is made to put a message on a queue that is full.
Event - Queue Service Interval High (events per second)
An event triggered when no messages are put to or retrieved from a queue within the timeout threshold.
Event - Queue Service Interval OK (events per second)
An event triggered when a message has been put to or retrieved from a queue within the timeout threshold.
Status - Current Depth
Current count of messages on a local queue. This measurement applies only to local queues of the monitored queue manager.
Status - Open Input Count
Current count of open input handles. Input handles are opened so that an application may "put" messages to a queue.
Status - Open Output Count
Current count of open output handles. Output handles are opened so that an application may "get" messages from a queue.

Channel Performance Counters

The following table describes the Channel Performance counters:

Measurement
Description
Event - Channel Activated (events per second)
Event generated when a channel, waiting to become active but inhibited from doing so due to a shortage of queue manager channel slots, becomes active due to the sudden availability of a channel slot.
Event - Channel Not Activated (events per second)
Event generated when a channel, attempts to become active but inhibited from doing so due to a shortage of queue manager channel slots.
Event - Channel Started (events per second)
Event generated when a channel is started.
Event - Channel Stopped (events per second)
Event generated when a channel is stopped, regardless of source of stoppage.
Event - Channel Stopped by User (events per second)
Event generated when a channel is stopped by a user.
Status - Channel State
The current state of a channel. Channels pass through several states from stopped (inactive state) to running (fully active state). Channel states range from 0 (stopped) to 6 (running).
Status - Messages Transferred
The count of messages that have been sent over the channel. If no traffic is occurring over the channel, this measurement will be zero. If the channel has not been started since the queue manager was started, no measurement will be available.
Status - Buffer Received
The count of buffers that have been received over the channel. If no traffic is occurring over the channel, this measurement will be zero. If the channel has not been started since the queue manager was started, no measurement will be available.
Status - Buffer Sent
The count of buffers that have been sent over the channel. If no traffic is occurring over the channel, this measurement will be zero. If the channel has not been started since the queue manager was started, no measurement will be available.
Status - Bytes Received
The count of bytes that have been received over the channel. If no traffic is occurring over the channel, this measurement will appear as zero. If the channel has not been started since the queue manager was started, no measurement will be available.
Status - Bytes Sent
The count of bytes that have been sent over the channel. If no traffic is occurring over the channel, this measurement will appear as zero. If the channel has not been started since the queue manager was started, no measurement will be available.
