Control Performance Monitor logging from the command line, this removes the graphical workload of Perfmon from the server making the reported values more accurate.
The Data Logging Service (DATALOG.EXE) is a Windows NT Service that performs the same function as the Performance Monitor Alert and Logging facility.
Syntax
MONITOR setup
MONITOR &qt;SYSTEMROOT&qt;SYSTEM32MyLogSet.PMW
MONITOR start
MONITOR stop
Key
SETUP is needed once only to install the service.
Use START and STOP to Start/Stop logging.
Save .PMW files from the PERFMON GUI under the file menu.Any graphical process running on a server will affect performance to some degree, most interactive programs (in particular the command prompt) will run faster when minimised.
Monitoring Hard Drives
To enable performance counters run:
diskperf -y
This enables the objects and counters for logical and physical disks .
To enable performance counters for a striped array run:
diskperf -ye
To disable performance counters run:
diskperf -N
or set in the registry HKLMSYSTEMCurrentControlSetServicesPerfDiskPerformance
REG_DWORD &qt;&qt;Disable&qt;&qt; = 1
Monitoring drive performance with perfmon will itself have a small impact on performance, any changes require a reboot and any errors will be logged in the event viewer. Disable perfmon when tuning is complete.
Alternatives:
Monitoring a server by running Performance Monitor from a remote workstation is a good alternative to the Data Logging Service that still gives accurate figures (and you don&qt;&qt;t need the resource kit to do this).
