SUMMARY

This article explains how to create a Performance Monitor log so that engineers can use it to troubleshoot performance problems on a computer running Windows NT.

MORE INFORMATION

Creating the Performance Monitor log:
  1. On the View menu, click Log.
  2. On the Edit menu, click Add To Log.
  3. In the Computer field, specify the name of the local computer or a remote computer you want to get a log of. In Objects, add the counters that you want Performance Monitor to log. These counters will change depending on the issue that you are troubleshooting.
  4. Click to highlight the objects that you wish to monitor and then click Add.
  5. Under Options click Log.
  6. Under File Name, name the log.
  7. In Update Time, set the interval according to how long you want to run the Performance Monitor log. If you want to run the log for an extended period of time, you will want to set this update time to an interval much higher than 15 seconds or the log will be very large. If you are going to run the log for only an hour, then 15 seconds will be fine.
  8. Click Start Log. The icon will change to a Stop Log icon once the log is started.
When you are ready to stop monitoring the selected objects and examine your log file, perform the following steps:
  1. Under Options click Log and then click Stop Log.
  2. In the Options menu click Data from, click Log File, and then click to select the radio button beside the perfmon.log field and locate your log file.

    NOTE: You cannot open a log file simply by clicking File and then clicking Open.
  3. After you open the log file, add the objects and counters that the log has monitored. Do this for each view needed, otherwise the log file's data will not be available.
If you are troubleshooting a performance issue or an issue that looks like a memory leak, the objects that Performance Monitor should log include but are not limited to the following items.

Memory resource issues:

Cache
Memory
Objects
Paging file
Process
Processor
System
Terminal Services (if a Terminal Server)

For all other resource issues, add additional counters:

Logical disk
NBT Connections
Network interface
Physical disk
Redirector
Server
Server work queues
Thread (do NOT capture if a terminal server)
All Terminal Server counters (if a Terminal Server)
All Protocol counters bound to network adapters
