Windows Azure Event Monitor

更新日期: 2010年12月

適用於: Operations Manager 2007

You create an event monitor for a Windows Azure application by using the Authoring console to create a monitor based on the event monitor type in the Windows Azure Management Pack. This monitor type sets a Critical or Warning state when a particular event is received and a Healthy state when a second event is received. The monitor must specify an expression for each event which requires some editing of XML.

This procedure provides an example of how to create an event monitor for a Windows Azure application. that sets a critical health state when an event 100 is detected and a healthy state when event 101 is detected. You can create other criteria by modifying the XML in the monitor’s configuration. Examples of other criteria are provided after the procedure.

Important重要事項
This procedure uses the Operations Manager Authoring console which is available as part of the System Center Operations Manager 2007 R2 Authoring Resource Kit (http://go.microsoft.com/fwlink/?LinkId=202663). This procedure cannot be completed using the Operations console.

Tip秘訣
This procedures uses display names for the components of the management pack. To have the Authoring console use display names, on the Tools menu, click Options, and then click Use display names. If you do not select this option, then the console will use actual names which will be different than the display names used here.

note附註

These are listed in the Events section of the Management Pack Authoring Guide at http://go.microsoft.com/fwlink/?LinkId=205695. The only exception is the event description which is not currently available.
