ADMINISTERING

Viewing Cluster Manager events and statistics
After distributing databases and mail servers to balance the workload, you should track the cluster events and statistics to be sure that the workload is acceptable and that failover occurs as expected. If the statistics show a problem, you may have to make some adjustments.

Viewing failover and workload balancing events

About this task

Whenever failover occurs, Domino® logs the event in the Domino server log file. A failover event may look like this:

08/23/2002 11:08:48 AM Failing over from Sales/Acme!!Customer.nsf for replica ID 852560C9:007232D, directing open to Sales2/Acme

When Domino fails over to balance the workload, the event may look like this in the Domino server log file:

08/23/2002 11:08:48 AM Load balancing off of Sales/Acme!!Customer.nsf for replica ID 852560C9:007232D, directing open to Sales2/Acme

You can view these events in the log file. Do one of the following.

Viewing a list of Cluster Manager statistics

Procedure

You can view a list of Cluster Manager statistics from the Domino Administrator, the Web Administrator, or the server console.

From the Domino Administrator or the Web Administrator

Procedure

1. In the Server pane, expand either All Servers or Clusters.

2. Select the server you want.

3. Click the Server -> Statistics tab.

4. In the statistics list, expand Server, and then expand Cluster.


From the server console

About this task

Send the following Domino command from the server console:

show stat server.cluster*

The Cluster Manager statistics begin with the string Server.Cluster. They give you information about failover, workload balancing, and the state of the servers in the cluster. Among other things, the statistics tell you how often the Cluster Manager attempted failover and workload balancing, and how many of these attempts were successful.

Note: To see the availability index, the availability threshold, and the expansion factor of the current server, send the Domino command show stat server from the server console.
