Add, Change, and Reorder Node Names in a Collection Definition

Performance Agent software writes the current cluster node names into the CPD collection definition in the schedule file. If a node is not a member of the cluster during installation, it is not included in this definition. If nodes are added to the cluster, you must add them to the collection definition. The Performance Agent uses the local node name, or list of node names in the case of a cluster, to schedule data collection. To add or remove a node name or to reorder the existing list, use the ADVISE COLLECT MODIFY command.

For example, the following command adds the node NEWSYS to the CPD collection definition:

$ ADVISE COLLECT MODIFY CPD NEWSYS

The following command adds all current nodes to the CPD collection definition:

$ ADVISE COLLECT MODIFY CPD *

The following command removes node SYSNOT from the CPD collection definition:

$ ADVISE COLLECT MODIFY/REMOVE_NODES=SYSNOT CPD

The following command reorders the nodes in all the collection definitions:

$ ADVISE COLLECT MODIFY/REORDER_NODES=(CNODE,BNODE,ANODE)

By default, the Performance Agent prepares reports according to the order of node names specified in the schedule file. You can reorder the list of names to cause a specific reporting order in your reports.
