Counter Thresholds

The Counter Thresholds tab enables you to maintain all counter objects/counters/instances associated with a monitor set. These are the same counter objects, counters and instances displayed when you run PerfMon.exe on a Windows machine.

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.

Add / Edit

Click Add or the edit icon to use a wizard that leads you through the six steps required to add or edit a counter.

Select a counter Object, Counter and, if necessary, a counter Instance using their respective drop down lists.
- Not all counters have related instances.
- The drop down lists used to select counter objects, counters, and instances are based on the "master list" maintained using the Monitor Lists page. If a counter object/counter/instance does not display in its respective drop down list, you can add it manually using Add Object, Add Counter, and Add Instance. You can also update the "master list" by scanning specific machine IDs using Update Lists By Scan.
Optionally change the default counter object Name and Description.
Select the log data collected. If the returned value is numeric, you can minimize the collection of unwanted log data by setting a narrow range of data values over and under the collection threshold.
- Collection Operator - For character string return values, the options are Changed, Equal or NotEqual. For numeric return values, the options are Equal, NotEqual, Over or Under.
- Collection Threshold - Set a fixed value that the returned value is compare to, using the selected Collection Operator, to determine what log data is collected.
- Sample Interval - Defines how frequently the data is sent by the agent to the server.
Specify when an alarm is triggered.
- Alarm Operator - For character string return values, the options are Changed, Equal or NotEqual. For numeric return values, the options are Equal, NotEqual, Over or Under.
- Alarm Threshold - Set a fixed value that the returned value is compare to, using the selected Alarm Operator, to determine when an alarm is triggered.
- Duration - Specify the time the returned values must continuously exceed the alarm threshold to generate the alarm. Many alarm conditions are only alarming if the level is sustained over a long period of time.
- Ignore additional alarms for - Suppress additional alarms for this same issue for this time period. This reduces the confusion of many alarms for the same issue.
Warn when within X% of alarm threshold - Optionally display a warning alarm in the View Console page when the returned value is within a specified percentage of the Alarm Threshold. The default warning icon is a yellow traffic light icon . See Monitor Icons.
Optionally activate a trending alarm. Trending alarms use historical data to predict when the next alarm will occur.
- Trending Activated? - If yes, a linear regression trendline is calculated based on the last 2500 data points logged.
- Trending Window - The time period used to extend the calculated trendline into the future. If the predicted trendline exceeds the alarm threshold within the future time period specified, a trending alarm is generated. Typically a trending window should be set to the amount of time you need to prepare for an alarm condition, if it occurs. Example: a administrator may want 10 days notice before a hard drive reaches the alarm condition, to accommodate ordering, shipping and installing a larger hard drive.
- Ignore additional trending alarms for - Suppress additional trending alarms for this same issue for this time period.
- By default, trending alarms display as a orange icon in the View Console page. You can change this icon using the Monitor Icons tab.
