ADMINISTERING
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.
From the Domino server log file
Procedure
1. Open the Domino server log file (LOG.NSF).
2. Click Miscellaneous Events.
3. Open the Notes® Log document you want to view.
You can view Cluster Manager statistic reports, or you can view a list of Cluster Manager statistics.
Viewing Cluster Manager statistic reports
Before using this procedure, you must enable statistic reporting in the Monitoring Results database.
1. In the Server pane of the Domino Administrator, expand either All Servers or Clusters.
2. Select the server you want.
3. Click the Server -> Analysis tab.
4. In the Task pane, expand Monitoring Results, and then expand Statistics Reports.
5. Click Clusters.
6. In the Results pane, open the document you want, and look in the Server cluster statistics section of the document.
Results
Note: If you prefer, you can view these reports directly in the Monitoring Results database (STATREP.NSF). Open the database, expand Statistics Reports, and then click Clusters.
Viewing a list of Cluster Manager statistics
You can view a list of Cluster Manager statistics from the Domino Administrator or the server console.
From the Domino Administrator
1. In the Server pane, expand either All Servers or Clusters.
3. Click the Server -> Statistics tab.
4. In the statistics list, expand Server, and then expand Cluster.
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.
