Are Customers Able to Synch Their Devices?

適用於: Exchange Server, Operations Manager 2007

The following monitors and rules for Exchange ActiveSync (EAS) perform synthetic EAS logons, and check the results to verify the availability and performance of Exchange ActiveSync on front-end servers running Exchange Server 2003.

Monitors for EAS Monitoring

Exchange EAS has two monitors:

  • Exchange ActiveSync Monitor

  • Exchange ActiveSync Heartbeat Interval Monitor

The Exchange ActiveSync Monitor performs a synthetic EAS logon, by default every 15 minutes, and verifies the health of EAS. If the monitor cannot log on and verify the health of EAS, it changes the state of EAS to critical and raises the following critical alert: "Exchange EAS monitor reported a problem."

Important重要事項
This monitor requires that Exchange Server 2003 Service Pack 1 is installed.

Exchange ActiveSync Heartbeat Interval Monitor helps verify that requests to Exchange ActiveSync do not expire before they have the opportunity to be processed. The monitor collects performance data on the specified interval, by default every five minutes, and verifies the average time it takes Exchange heartbeats by the most recently connected devices to be received by the front-end server is within the calculated baseline. If the average rate of Exchange heartbeats is above the baseline, a warning alert is raised. For more information about baseline monitoring, see "Self-Tuning Threshold Monitors in Operations Manager 2007" (http://go.microsoft.com/fwlink/?LinkId=86799) in the Operations Manager 2007 Help.

Key Rules for EAS Monitoring

There are approximately 50 rules to help you monitor the health of EAS. Following are some of the more important rules for verifying the ability of devices to log on to the Exchange server and the performance of EAS.

 

Rule Name

Alert properties

ActiveSync: Pending I/O requests to Exchange server

Not applicable: This rule collects performance data; it does not generate alerts.

ActiveSync: rate of incoming changes from ActiveSync devices (changes\sec)

Not applicable: This rule collects performance data; it does not generate alerts.

ActiveSync: rate of I/O request to Exchange server (requests/sec)

Not applicable: This rule collects performance data; it does not generate alerts.

ActiveSync: rate of outgoing changes sent to ActiveSync devices (changes\sec)

Not applicable: This rule collects performance data; it does not generate alerts.

ActiveSync: Total number of unrecognized requests since last service start

Not applicable: This rule collects performance data; it does not generate alerts.

ActiveSync: Total number of users since last service start

Not applicable: This rule collects performance data; it does not generate alerts.

Current number of ActiveSync users

Not applicable: This rule collects performance data; it does not generate alerts.

Performance Collection Rule for Exchange ActiveSync logon latency

Not applicable: This rule collects performance data; it does not generate alerts.

Views for EAS Monitoring

The views for EAS monitoring are in the Operations Console Monitoring pane in the Microsoft Exchange Server\Exchange 2003\Active Sync node. The views for EAS monitoring are as follows:

  • EAS Active Alerts

  • EAS Logon Latency

  • EAS Performance Data

The EAS Active Alerts view displays alerts generated by the EAS monitors and rules. For more information about an alert, see its properties in the Operations Manager 2007 Operations Console.

The EAS Logon Latency view displays performance data in graphical format for EAS logon latency. You do not need to wait for customers to call the help desk with mobile device logon issues. If the time it takes to log on is increasing, you can investigate the issue and resolve it before an alert is ever raised.

The EAS Performance Data view displays key performance data for the EAS servers in graphical form. Select the items you want charted, such as the rate of incoming changes from ActiveSync devices (changes\sec), for each managed front-end server.

Reports for EAS Monitoring

There are two reports provided with Operations Manager 2007 that can help you analyze trends in EAS for your Exchange environment: Availability and Performance. These reports are located in the Operations Console Reporting pane in Reporting\Microsoft Generic Report Library.

Reporting is an optional component of Operations Manager 2007.
