 To specify settings in the B<monsetting> table, use 'xcatmon' as the name, 'apps' as the key and the value will be a list of comma separated list of application names. For each application, you can specify the port number that can be queried on the nodes to get the running status. Or you can specify a command that can be called to get the node status from. The command can be a command that can be run locally at the management node or the service node for hierarchical cluster, or a command that can be run remotely on the nodes.
