Topic Last Modified: 2007-11-16

The Microsoft Exchange Server 2007 Management Pack for Operations Manager includes a performance data collection engine that is used to query performance counter objects on computers that are running Exchange Server 2007. For this Operations Manager rule, data is collected using the performance counter specified in the Details table.

To review the value of the performance counter that generated this alert, in the Operator Console, select this alert, and then click the Properties tab.

RPC Averaged Latency - sustained for 5 minutes - Red(>70 msec)

The RPC Averaged Latency performance counter records the average time, in milliseconds (ms), that it takes for the last 1,024 packets to be processed. If the RPC Averaged Latency performance counter value is lower than 50 ms, the server can process the requests in a reasonable amount of time. If the counter value stays greater than 50 ms for more than several seconds, this indicates that the server is having difficulty keeping up with the load. As a result, users may experience delays when accessing their e-mail messages.

This alert indicates that the RPC Averaged Latency performance counter has stayed greater than 70 ms for 5 minutes and users may experience delays. Another symptom you may experience when this threshold is reached is a popup window on the Microsoft Outlook client stating that Outlook is retrieving data from the Microsoft Exchange server. This alert may be caused by increased remote procedure call (RPC) load, or a bottleneck in one or more resources.

To resolve this critical error, determine the resources that are creating a bottleneck and attempt to mitigate the problem. Possible bottlenecks include disk reads or writes, processor time, available memory, and network configuration.

If you are having difficulty resolving the issue, contact Microsoft Product Support. For information about contacting support, visit the Contact Us page of the Microsoft Help and Support Web site.

If you are not already doing so, consider running the tools that Microsoft Exchange offers to help administrators analyze and troubleshoot their Exchange environment. These tools can help you make sure that your configuration is in line with Microsoft best practices. They can also help you identify and resolve performance issues, improve mail flow, and better manage disaster recovery scenarios. Go to the Toolbox node of the Exchange Management Console to run these tools now. For more information about these tools, see Toolbox in the Exchange Server 2007 Help.
