Unknown StartTrace Error Message. ExMon refresh the real time data every 1minute. If there is a lot of data in Exchange server then ExMon can be crashed while collecting the data with the message ExMon has stopped working. You need to choose between check online or close the program. This error occur because there is an old Event Trace is still running in the background.

You need to stop this old trace using a tool called Tracelog. You have to make sure Exmon. Logman stop "Exchange Event Trace" -ets.

After completing the above steps, now your ExMon will work correctly. Sign up today to participate, stay informed, earn points and establish a reputation for yourself! CPU time is reported in milliseconds of processing time, which depends on the server hardware. For example, one millisecond of processing time on a MHz processor is equal to approximately two milliseconds of processing time on a MHz processor.

The data displayed in the server latency columns documents the time that is required to process user requests. ExMon enables you to view this data for individual users. You can obtain more accurate results by gathering long traces over more than 30 minutes or even over several hours. The data displayed in the Avg. Client Latency ms column is a superset of the CPU time and the server latency. Client latency includes not only server latency, but also any network delay that is caused by issues with the network, packet retransmission, and network bandwidth.

For users who use Outlook without Cached Exchange Mode, high client latency times directly affect how frequently Outlook is unresponsive. ExMon reports client latency for each request, while Outlook may require multiple requests to complete an operation. This means that the client latency reported by ExMon provides a lower bound to the responsiveness that users may experience. Generally, if the minimum client latency is consistently more than milliseconds, the user experiences poor responsiveness in Outlook in traditional online mode.

Improvements in Outlook with Cached Exchange Mode help hide this latency from the user and enable site consolidation by moving many important tasks, such as reading and sending mail, to the background. When a user is using Outlook Cached Exchange Mode, consistent average client latencies of milliseconds or more can be hidden from the user. With client latencies of more than milliseconds and low network bandwidth, users may benefit from Cached Exchange Mode that is configured to download only mail headers.

Foreground client latency is a measure of specific types of Outlook requests. These specific types are operations that are not in the background. For example, updating rules, browsing public folders, and delegate access are not optimized to use background communication.

The Avg. Foreground Client Latency ms data informs administrators about operations that cause client unresponsiveness. To understand the overall effect on the user, make sure that you compare the approximate percentage of foreground packets to all packets. The network bytes columns document the amount of data and control codes that are sent to and from Exchange Server. However, it does account for compression that is used by Exchange Server , and Outlook and later versions.

The amount of network traffic depends heavily on the usage profile. Also, the number and size of attachments and the time of day affects the amount of network traffic. To more accurately measure network usage, use longer monitoring periods. A: File size depends on the Exchange server load. A: Tracing time depends on user activity and how you want to use the data.

For good averages across all users, it is recommended that you collect data for at least 30 minutes during a period of expected user activity. Some client monitoring data is collected only at certain intervals.

Therefore, collecting data for longer may increase the probability of more complete data. When you troubleshoot individual users and problems, traces of one to five minutes are generally sufficient. A: Yes.

ExMon can be run with any language that is supported by Exchange Server and any language that is supported by Windows.

ExMon supports Unicode display names for users. However, the ExMon tool interface and documentation are available only in English.

To minimize the effect, you should not collect data on a hard disk drive that is currently being used by Exchange, such as the database, streaming, log file, or queue drives.

ETW was designed especially for performance tracing and is used by core parts of Windows. As a result, the effect on the server is less than two percent additional processing time and a negligible additional latency. A: No, you currently cannot write your own data parser. The raw data requires a significant amount of analysis to produce meaningful data. A: Because of limitations in the tracing and parsing code, ExMon truncates user display names to 32 characters.

A: Some data columns are blank because some servers do not provide some information. Since the release of Exchange Server , significant changes have been made.

ExMon supports data files from all these servers, although not all the data is available. It also requires that users also have Outlook SP1. A: Tracing ExMon data on Exchange servers that use Cluster Service is difficult because you care about collecting data for a specific virtual server instead of data from just a physical node.

A cluster failover during a data collection session causes incomplete data. By collecting on shorter intervals, such as five minute intervals, on every node of the cluster, you can minimize the amount of data that is lost if there is a failover. For more details on how this is accomplished see the ExMon documentation located in the ExMon installation directory.

ETL Files. All the data collected by ExMon can be exported to a comma-separated text file. For example the below command exports the By User data to a. Before you start using the ExMon tool I thought I would tell you about an issue you should be aware of.

There have been several cases where different Exchange administrators, when executing ExMon. Figure 8 : Unknown StartTrace Error The Error message can happen if ExMon crashes or is killed while collecting data, the reason being the Exchange trace continues. Personally I got a bit scared when I saw the trace just continued, but fortunately I later found out it had a limit of MB where the trace will stop collecting automatically.
