CLUSTERS

Managing and monitoring the ICM
The ICM records significant events, such as not being able to find a database, in the Miscellaneous Events view in the log file. You can also view ICM statistics from the IBM® Lotus® Domino™ Administrator, the Web Administrator, or the server console. You can use these events and statistics, in conjunction with the Cluster Manager and Cluster Replicator events and statistics, to determine which servers in the cluster are the busiest so you can better balance the workload in the cluster.

Viewing the log file

To view ICM events in the log file, do one of the following.

From the Domino Administrator or the Web Administrator

1. In the Server pane, select the server that stores the log file you want to view.

2. Click the Server - Analysis tab.

3. In the Task pane, expand IBM® Lotus® Notes® Log, and then click Miscellaneous Events.

4. In the Results pane, open the document you want to view.

From the Domino server log file

1. Open the Domino server log file (LOG.NSF).

2. Open the Miscellaneous Events view.

Viewing ICM statistics

The ICM generates statistics that indicate how the cluster and the ICM are performing. To view these statistics, you can do one of the following.

From the Domino Administrator or the Web Administrator

1. In the Server pane, select the server you want.

2. Click the Server - Statistics tab.

3. In the Statistics list, expand ICM.

From the server console

Type show stat icm

Monitoring all the ICM servers at the same time

You can use the Domino server monitor to monitor all the ICM servers at once. You can decide what information you want to monitor and how to display that information. You can monitor the ICM servers and the entire cluster while you monitor other Domino servers. To tell Domino which servers to monitor and what information to monitor on each server, you create or customize a monitoring profile.

Note The Domino server monitor and monitoring profiles are not available in the Web Administrator.

Starting the server monitor

You can start the server monitor manually while the server is running, or you can start the server monitor automatically when the server starts.

To start the server monitor manually
1. From the Domino Administrator, click the Server - Monitoring tab.

2. In the "Monitoring profiles" field, select the profile you want.

3. Click the Start button.

Once pressed, the Start button becomes the Stop button.

To start the server monitor automatically when the server starts
1. Choose File - Preferences - Administration Preferences.

2. Click Monitoring.

3. Select "Automatically monitor servers at startup."

4. Make any other changes you want, and then click OK.

For more information about monitoring Domino servers, see the topic Monitoring.

Creating or customizing a monitoring profile for the ICM

You can create new profiles and edit existing profiles to customize the tasks and statistics that Domino displays.

1. From the Domino Administrator, click the Server - Monitoring tab.

2. In the "Monitoring profiles" field, select an existing profile.


3. To add one or more tasks to monitor, choose Monitoring - Monitor New Task, select the tasks you want to add, and then click OK.
4. To add one or more statistics to monitor, choose Monitoring - Monitor New Statistic.

5. In the "Add Statistic(s) to this profile" dialog box, expand ICM, select the ICM statistics you want to monitor, and then click OK. For example, the Command - Redirects statistics and the Requests statistics tell you how busy each ICM is. This can help you to balance the workload.

6. (Optional) To add a server to the profile, select Monitoring - Monitor New Server, and then select the server from the list; or drag a server from the Server pane to the server monitor.
