To monitor a machine's status, you must install a Datareplicator agent at the subject machine. Datareplicator agent collects the status of all Datareplicators installed on the machine and passes the information to JP1/Cm2's SNMP agent. The SNMP agent passes this Datareplicator status information to the JP1/Cm2/Network Node Manager at the supervisor machine. Datareplicator's icon color on the JP1/Cm2/Network Node Manager screen is determined on the basis of this information.

Under the JP1/Cm2/Network Node Manager's default settings, green indicates normal, yellow indicates command shutdown, and red indicates error shutdown. The following figure provides an overview of using JP1/Cm2 for status monitoring.

Explanation

1. At a specified interval, the supervised machine's Datareplicator agent collects information about each Datareplicator process. This monitoring interval can be changed by the hdsagtopt command.
2. Depending on the processing status, the supervised machine's Datareplicator agent sends information to the JP1/Cm2 SNMP agent.
3. The supervisor machine's JP1/Cm2 SNMP agent passes the information to JP1/Cm2/Network Node Manager and changes the icon color.
