Auto Learn - Monitor Sets

Monitor > Agent Monitoring > Assign Monitoring > Auto Learn

The Auto Learn Alarm Thresholds window maintains auto learn alarm thresholds for monitor sets.

You can enable Auto Learn alarm thresholds for any standard monitor set you assign to selected machine IDs. This automatically fine-tunes alarm thresholds based on actual performance data on a per machine basis.

Each assigned machine collects performance data for a specified time period. During that time period no alarms are triggered. At the end of the auto learn session, the alarm threshold for each assigned machine is adjusted automatically based on the actual performance of the machine. You can manually adjust the alarm threshold values calculated by Auto Learn or run another session of Auto Learn again. Auto Learn cannot be used with individualized monitor sets.

Select Page

When more rows of data are selected than can be displayed on a single page, click the and buttons to display the previous and next page. The drop-down list alphabetically lists the first record of each page of data.

Edit

A list of objects/instance/counters displays for the selected monitor set you want to setup to "auto learn". Click the edit icon to use a wizard that leads you through the three steps required to edit auto learn alarm thresholds.

1. Enable Auto Learn for this object/counter/instance combination, if appropriate, by selecting Yes - Include. If No - Do not include is selected, no other selections in this wizard are applicable.
   • Time Span - Enter the period of time performance data is collected and used to calculate alarm thresholds automatically. Alarms will not be reported during this time period.
2. Displays the Object, Counter and, if necessary, the counter Instance of the alarm threshold being modified. These options cannot be changed.
3. Enter calculated value parameters.
   • Computation - Select a calculated value parameter. Options include MIN, MAX or AVG. For example, selecting MAX means calculate the maximum value collected by an object/counter/instance during the Time Span specified above.
   • % Increase - Add this percentage to the Computation value calculated above, with the Computation value representing 100%. The resulting value represents the alarm threshold.
   • Minimum - Set a minimum value for the alarm threshold. The value is automatically calculated as two standard deviations below the calculated Computation value, but can be manually overridden.
   • Maximum - Set a maximum value for the alarm threshold. The value is automatically calculated as two standard deviations above the calculated Computation value, but can be manually overridden.

     Note: Once auto learn is applied to a machine ID and runs for the specified time period, you can click the override auto learn icon for a specific machine ID and manually adjust the calculated alarm thresholds values. You can also re-run Auto Learn again, using a new session of actual performance data to re-calculate alarm threshold values.
