Monitoring the health of high availability and disaster recovery configurations

Status notifications are issued when HA and DR queue managers, and the HA group, changes state. You can use these notifications to track the health of the HA or DR configuration.

These notifications are written as messages to mqerr:/MQSystem.log (see IBM MQ appliance logs), providing an audit of HA and DR events. Both primary and secondary instances of HA and DR queue managers issue notifications.

You can set up appliance log targets and send these HA and DR health notifications to a log target to provide real-time monitoring of HA and DR configurations (see Appliance log targets).

The following topics give examples of sequences of notifications that can be issued by HA or DR configurations.
