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 is a key component of Microsoft Windows management services, and an integral part of Windows 2000, Windows XP, Windows 2003, Windows 2008, and Vista. 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. CategoriesDisplays the Monitoring Categories to which the Monitor is assigned. Click to select or deselect Monitoring Categories. Right click to create or edit Monitoring Categories. Test MonitorTest any Monitor Item against any Agent capable of running the Item using the drop-down and Test button on this dialog box. Testing a Monitor Item prior to putting it into production validates that the monitor item is configured properly. To test a monitor item: 1.Select the Agent you wish to test against from the drop-down list. 2.Click the Start Test button. If the test was successful, you will receive a pop-up indicating this and the option to see detailed results of the test. If the test failed, detailed results of the test will automatically open in Notepad. ScheduleDisplays the Scheduled Interval and Scheduled Hours settings which control the frequency for the Monitor Item. Scheduled Interval tabSpecify 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 tabSelect 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. Properties TabThis read-only tab displays the properties of the selected object and the values for those properties.
