If you are using Windows Management Instrumentation (WMI) -- the Microsoft implementation of Web-Based Enterprise Management (WBEM) -- you can use WMI Monitors to query a WMI namespace and database. WMI monitor items periodically query the Windows Management Instrumentation database and generates events when the results of the query change.

WMI Monitor Settings

•Namespace - Enter the name of the WMI namespace to query. This is usually root/cimv2.

•Query - Enter the query to execute. This query is the base query which retrieves zero or more records from the WMI repository.

Actions

•Warning 5537 - The results of the WMI query are different from the results the last time the query ran.

Specify the interval at which the monitoring, polling or action is to occur. Depending on the Monitor Item type, Items can be scheduled in interval increments of Seconds, Minutes, Hours and Days. The Scheduled Interval is relative to the top of the hour or top of the minute. For example, if a Scheduled Interval is configured for 10 minutes, the Monitor Item will execute at hh:10:00, hh:20:00, hh:30:00, hh:40:00, hh:50:00, h1:00:00, etc. If a Scheduled Interval is configured for 15 seconds, the Monitor Item will execute at hh:00:15, hh:00:30, hh:00:45, hh:01:00, hh:01:15, etc.

Scheduled Hours tab

Select the days and/or hours this item is active. By default, the schedule is set to ON for all hours and all days. Mouse clicks toggle squares between ON and OFF. Clicking on an individual square will toggle the active schedule for that hour. Clicking on an hour at the top of the grid, or on a day of the week at the left of the grid will toggle the corresponding column or row. Keyboard equivalents are the arrow keys and the space bar.
