You can perform the following tasks to troubleshoot server performance using the Domino server monitor:

• Open a different Domino Administrator tab from the Domino server monitor
• Display the differences in current and previous statistic values
• View additional information about a server or server task
• Create an event handler for a server that is down

Example using the Domino server monitor

Suppose you are monitoring eight servers and are troubleshooting errors. Server Hub-E/East/Acme appears at the top of the server list and displays a failure indicator. In the By State view, you notice that one of the status indicators is reporting a Failure error. You can tell from the column which server task is reporting the error, but you still don't know what the error is. Hover over a task status indicator or to see a brief explanation of the problem. To take immediate constructive action on the server, you select the server, right click and select Display Status Tab. You are now ready to diagnose and take corrective action from the Server - Status tab.

Or perhaps you are monitoring 14 servers, and troubleshooting dead mail statistics (dead.mail). To see which servers have the highest amount of dead mail, sort the statistic column so that the servers with the most dead mail messages appear at the top. To get an idea of when the dead mail really started piling up, locate the cursor in the Dead statistic column and right click. Select Show Statistic's Difference to see if the error occurred within the last hour. To release the dead mail, right click and select Display Messaging tab to switch to the Messaging - Mail tab.

To open a different Domino Administrator tab from the Domino server monitor

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

2. Select a server.

3. From the Monitoring menu, select one:

• Display Status Tab -- To view the status and access the Server Console to issue commands for the selected server
• Display Messaging Tab -- To monitor mail tracking for the selected server

For numerical statistics, you can display the difference between the current statistic value and its value from one hour earlier. A delta icon appears in the statistic column when the earlier, or "differences" value is displayed. If the server monitor has been running less than one hour, it displays the difference between the current statistic value and the oldest value available.

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

2. Click in the statistic column to select the statistic.

3. From the Monitoring menu, select "Show Statistic's Difference."

4. To remove the difference value and icon, click the statistic column, and chose Monitoring - Show Statistic's Difference again.

To view additional information about a server or task

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

2. Do one:

• Server tasks -- In either view, locate the cursor in the tasks frame and hover over the error indicator to see what event cause the error.
• Servers -- In either view, locate the cursor in the server pane and hover over the error indicator to see what event cause the error.

You can generate statistic events and invoke event handlers when a server goes down or comes back up, when a task reports an error, or when a statistic has reported a particular threshold.

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

2. Do one:

• Locate the cursor in the server pane and right click. Select "Create event handler" to create an event handler when a server goes down.
• Locate the cursor in the tasks pane and right click. Select "Create event handler" and then select one of the following to create an event handler when a task reports an error.

Any Error (Local)

Current Error (Local)

Current Status (Local)

Current Error (On Server)

• Locate the cursor in the statistics pane and right click. Select "Create event generator" and then select either local or server to create a new statistics event generator.
