ChannelStatistics (MQLONG)

This controls the collection of statistics data for channels.

The value is one of the following:

MQMON_NONE

Disable data collection for channel statistics for all channels regardless of the setting of the STATCHL channel attribute. This is the default value.

MQMON_OFF

Turn statistics data collection off for channels that specify QMGR in the STATCHL channel attribute.

MQMON_LOW

Turn statistics data collection on with a low ratio of data collection for channels specifying QMGR in the STATCHL channel attribute.

MQMON_MEDIUM

Turn statistics data collection on with a moderate ratio of data collection for channels specifying QMGR in the STATCHL channel attribute.

MQMON_HIGH

Turn statistics data collection on with a high ratio of data collection for channels specifying QMGR in the STATCHL channel attribute.

For most systems you are recommended to use MEDIUM. However, for a channel that processes a high volume of messages each second, you might want to reduce the sampling level by selecting LOW. Also, for a channel that processes only a few messages, and for which the most current information is important, you might want to select HIGH.

This attribute is supported only on iSeries, UNIX systems, and Windows.

To determine the value of this attribute, use the MQIA_STATISTICS_CHANNEL selector with the MQINQ call.
