member list command

The member list command lists the members in the cluster and the member status. At least one container member must be running for this command to function properly.

Usage notes

Important: If you start AS4 Microservice by using the member start_service command, a delay of several minutes might occur before you can run the member list command. The delay occurs because of the time that is needed to start each member of the node as a Windows service.

You can use Java™ Management Extensions (JMX) technology to access the same information that you display when you run the member list command. You can view the JMX-related information with a tool like JConsole.

If you run the member list command on multiple nodes and the times in the Last Heartbeat column vary more than you expected, synchronize the time clocks between all nodes.
