Viewing current performance activity

You can view the current performance activity of a server using the Tivoli® Performance Viewer in the administrative console.

1. Click Monitoring and Tuning > Performance Viewer > Current® Activity in the console navigation tree.
   The Tivoli Performance Viewer current activity collection is displayed.
2. Start monitoring the current activity of a server in either of two ways:
   • Under Server, click the name of the server whose activity you want to monitor. Clicking on the name starts the monitoring for the server and displays the activity page for the server.
   • Select the check box for the server whose activity you want to monitor, and click Start Monitoring.To start monitoring multiple servers at the same time, select the servers and click Start Monitoring.
   A Tivoli Performance Viewer console panel is displayed, providing a navigation tree on one side and a view of real-time data on the current performance activity of a server on the other side.
3. From the navigation tree, select the server activity data that you want to view.
