Auto Learn - SNMP Sets

Monitor > Assign SNMP > Auto Learn

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

You can enable Auto Learn alarm thresholds for any standard SNMP set or quick set you assign to selected SNMP devices. This automatically fine-tunes alarm thresholds based on actual performance data on a per SNMP device basis.

Each assigned SNMP device generates 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 SNMP device is adjusted automatically based on the actual performance of the SNMP device. 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 SNMP sets.

To apply Auto Learn settings to selected SNMP devices:

  1. Select a standard SNMP set using the <Select SNMP Set> drop-down list. Or click the edit icon of an SNMP set already assigned to a device to populate the <Select SNMP Set> drop-down list with its identifier.
  2. Click Auto Learn to display the Auto Learn popup window. Use a wizard to define parameters used to calculate alarm threshold values.
  3. Assign this standard SNMP set, modified by your Auto Learn parameters, to selected SNMP devices, if not already assigned.

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 SNMP device and manually adjust the calculated alarm threshold values. You can also re-run Auto Learn again, using a new session of actual performance data to re-calculate alarm threshold values.

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

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 SNMP object, 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 SNMP Object of the alarm threshold being modified. This option cannot be changed.
    • Interface
  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 SNMP object 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.
