Troubleshoot an Application Performance Problem

Use this procedure to troubleshoot a performance problem with an application. You can use the same procedure to investigate a problem with a network or server by clicking a link to narrow by metric, network, or server.

A user from corporate headquarters reports a performance problem with an application.

Follow these steps:

1. Click the Operations page.
2. Click Applications in the Show Me menu.
3. Determine if the application in question has bubbled to the top of the Performance by Application list.

   If the application does not appear at the top of the list, select a larger Size setting. If the application does not appear on the list, the management console might not monitor it.

4. Click the performance bar next to the application name to show details about the application.

   

   A detail page shows related metrics, networks, and servers you can use to navigate into data related to the problem.

5. (Optional) If you know the network or server that hosts the application, click the appropriate performance bar to narrow the scope of data.

   

6. Click History in the Show Me menu.
7. Review the application history on the History page to identify and note systematic patterns of unavailability or compromised performance.

   

8. Click Performance in the Show Me menu, and then Explore to begin troubleshooting.
9. Perform more exhaustive troubleshooting by clicking the Engineering link at the top of the detail page.

   

10. Review the Response Time Composition: Average view on the Components Report page to pinpoint the time the reported issue occurred.

    

11. Identify which metric is the significant contributor to the performance problem at that point. If the metric that sees an increase in response time is:
    • Server Response Time (SRT), troubleshoot an increase in Server Response Time
    • Network Round Trip Time (NRTT), troubleshoot an increase in Network Round Trip Time (NRTT)
    • Retransmission Delay, troubleshoot an increase in Network Round Trip Time (NRTT)
    • Data Transfer Time, troubleshoot an increase in increase in Data Transfer Time

If the metrics report acceptable performance with respect to the historical timeline, the problem might be with the user’s computer.
