Configuring automatic APS threshold calculation
The baselining process can be started when initially creating the APSApplication Perfromance Score object or upon editing an APS object. At any time you can restart the baselining process if you would like the system to recalculate the thresholds.
- Go to Configuration > Objects > Service Levels > Application Performance Score.
- On the Add New APS Object form, ensure that the Auto Baseline checkbox is checked and set how long you want the system to observe traffic when calculating the thresholds by using the Auto Baseline Period drop-down list. Select the time period for the baselineused by monitors and performance reports to establish a standard by which sunsequent performance can be measured based on how popular the application is. For example, if there is a lot of HTTP traffic on the network, the 1 hour period will be long enough to analyze traffic and create an accurate baseline. For an application that is not used very often, use the 1 week baseline period to ensure that enough traffic is analyzed to generate baseline recommendations.
- Or on the Edit APS Object form, set the Auto Baseline Period and click Start Baseline.
NOTE
The Network Loss metric is not calculated during the baseline analysis.
NOTE
If no traffic matching this APS object is observed during the baseline period, the appliance restarts the baseline analysis for the next larger time period. For example, if no traffic observed during the one hour period, the traffic continues to be analyzed for one day. If no traffic is observed during the one day period, then the traffic is analyzed for a week. If the traffic is analyzed for one week and no traffic has been transferred, the auto baseline analysis stops.
Each time the system unsuccessfully baselines the traffic (that is, when no traffic is observed during the auto baseline period), an email notification is sent to the users configured on the Configuration > System > Network > Email page.
