ClusterSenderStatistics (MQLONG)
Because cluster sender channels can be automatically defined from the definition of CLUSRCVR in the repository, you cannot alter the setting of the STATCHL attribute for these auto-defined cluster sender channels using ALTER channel. For these channels the decision of whether to collect online monitoring data is based on the setting of this queue manager attribute.
The value is one of the following:
- MQMON_Q_MGR
- Statistics data collection for auto-defined cluster sender channels is based on the value of the queue manager attribute STATCHL. This is the default value.
- MQMON_OFF
- Switch off statistics data collection for auto-defined cluster sender channels.
- MQMON_LOW
- Switch on statistics data collection for auto-defined cluster sender channels with a low ratio of data collection.
- MQMON_MEDIUM
- Switch on statistics data collection for auto-defined cluster sender channels with a moderate ratio of data collection.
- MQMON_HIGH
- Switch on statistics data collection for auto-defined cluster sender channels with a high ratio of data collection.
To determine the value of this attribute, use the MQIA_STATISTICS_AUTO_CLUSSDR selector with the MQINQ call.
