Managing Application Performance OLAs › Edit an Application Performance OLA

Edit an Application Performance OLA

Edit a performance OLA to change the expected levels of service for a user-defined application on a group of networks that are identified by network type.

The management console creates a default OLA for each user-defined application to measure performance across all networks that do not have an assigned network type. In general, this is not recommended for monitoring Network Round Trip Time and Total Transaction Time because of differences in network latency between remote locations.

When you update the threshold values in a default OLA, your changes are dynamically applied to any new OLAs for that application that are configured to use the default OLA’s value. For example, if the default OLA for the POP3 application requires at least 90% of the observations for Network Round Trip Time during a 1-hour interval to be at least 5ms, and you create an OLA for the POP3 application in the Austin network type, the default percentage of observations is 90% and the Network Round Trip Time threshold is 5 ms. If you change POP3’s default OLA threshold for Network Round Trip Time, the management console dynamically updates the Network Round Trip Time threshold for POP3 Austin’s OLA to use the new default value.

If you change the number of thresholds or minimum observations for an OLA metric without customizing the threshold values, the change applies to the default OLA.

Follow these steps:

1. Click the Administration page.
2. Click Data Monitoring, Applications in the Show Me menu.
3. Scroll to the Application list, select the applications you want, and click OLAs.

   Edit Application OLAs opens and the OLAs for the selected applications are listed by network type.

4. Click to edit the network type that corresponds to the performance OLAs for a group of client networks.

   (Optional) To edit the performance OLA for more than one remote location, select the appropriate network types, and click to edit the selected OLAs.

   Edit OLA Thresholds opens.

5. Edit the threshold settings for each OLA metric and click OK.

   For information about setting server properties, click Help.

6. Click the link to synchronize monitoring devices with the current client network, server subnet, and application definitions on the management console.

   Monitoring devices temporarily stop monitoring application performance during synchronization. To minimize interruptions to monitoring, complete all of your changes before synchronizing monitoring devices.

7. Wait a full reporting cycle, up to one hour, to see how the threshold changes compare to the actual response times observed by the management console.
   1. On the Management page, in the Show Me menu, click Performance Detail OLA.
   2. (Optional) Adjust the values for an operational level threshold. For example, if the threshold for Network Round Trip Time is less than 11 milliseconds at the 90th percentile, but only 67.744 percent of the observations meet this threshold level, adjust the threshold level percentile or the threshold level so that the application meets the operational level agreement for the remote site.
