Pipeline tracing is enabled. This may degrade system performance. |
Explanation
This Warning event indicates that transport pipelining is enabled on a server that has Microsoft Exchange Server 2007 installed. Pipeline tracing is a diagnostic feature in Exchange 2007 that enables you to capture diagnostic information about e-mail messages as they encounter transport and routing agents that are registered on Simple Mail Transfer Protocol (SMTP) events in the transport pipeline.
Pipeline tracing produces significant diagnostic logging and can affect the performance of the Exchange server. If left enabled for a long time, pipeline tracing can potentially use a significant amount of disk space. Therefore, pipeline tracing should only be enabled for short periods of time to diagnose or investigate immediate and specific transport agent or routing agent problems.
The diagnostic logging that is produced by pipeline tracing includes all the contents of the message as it passed through the transport agents and routing agents. Therefore, it's recommended that the pipeline tracing output directory be secured so that only authorized people can access the directory.
User Action
No user action is required for this warning if pipeline tracing has been enabled to troubleshoot or investigate an immediate and specific transport agent or routing agent problem. However, remember that pipeline tracing should be left enabled only long enough to gather enough information to help you investigate a current problem. Consider doing one of the following:
If you no longer need pipeline tracing enabled, disable it by running the following command on the Exchange server on which this warning was generated:
Set-TransportServer <Identity> -PipelineTracingEnabled $False
In this command, replace <Identity> with the name of the Hub Transport server on which you want to disable pipeline tracing. For example:
Set-TransportServer Hub01 -PipelineTracingEnabled $False
If pipeline tracing has consumed a significant amount of disk space, you can safely move all the log files that are located in the pipeline tracing log directory to another location. You can determine the location of the pipeline tracing log directory by running the following command:
Get-TransportServer <Identity> | Format-List PipelineTracingPath
In this command, replace <Identity> with the name of the Hub Transport server on which you want to view the location of the pipeline tracing log directory location. For example:
Get-TransportServer Hub01 | Format-List PipelineTracingPath
If pipeline tracing should be enabled, monitor available disk space closely to make sure pipeline tracing doesn't consume available disk space. Also, verify that only authorized people can access the pipeline tracing log directory.

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.
