Using OSM to Generate ServerNet Cluster Statistics

Each processor in every node of a ServerNet cluster keeps message system counters

regarding communication with each node in the cluster, including the local node. In

addition, each processor keeps a set of generic counters that are not associated with

any particular node.

Each hour, SNETMON sends a request to the MSGMON process in each processor to

send message system statistics to the service log ($ZLOG). The data is in the form of

an event: the ZSCL-EVT-STATISTICS: Node Statistics (1200) event. This event

provides a snapshot of message-system error counters for the ServerNet Cluster

subsystem. The counters are reset after the statistics data is recorded.

Using the OSM EMS Event Viewer Application, you can view Node Statistics events as

they are logged hourly. Or you can use the OSM Service Connection to generate these

events at random for the server where you are logged on.

To generate and view the statistics event for a node:

1. Right-click the local or remote node, and select Actions. The Actions dialog box

appears.

2. Select Generate ServerNet Statistics from the Available Actions list.

3. Click Perform action. The Action Status window shows the progress of the action.

4. Click Close to close the Actions dialog box.

5. Use the OSM Event Viewer Application to check the statistics event for the system

you are validating:

a. Start the event viewer and log on. Be sure to include the service log ($ZLOG)

in the event source criteria.

b. Find the Node Statistics (1200) event.

c. Double-click the event to show the tokens and their descriptions. Or select the

event, and then select Detail from the Display menu. The Event Viewer

displays the Event Detail window for the selected event. For more information

about the Node Statistics (1200) event, see the Operator Messages Manual.

Note. Statistics should be interpreted only by a service provider trained by HP.

Note. The counters are reset automatically each hour. To reset the counters manually

at any time, use the Reset ServerNet Statistics action for the ServerNet Cluster

resource. Resetting the counters also produces a series of Node Statistics (1200)

events.
