Typeperf.exe: Performance Data in the Command Window

This command-line tool displays real-time data from System Monitor counters in a command window. You specify the counters and the update interval in a command-line string; TypePerf returns the values of the requested counters at the specified intervals and displays them in the command prompt window until you stop it by pressing any key.

TypePerf's performance data come from internal hardware and software counters, just as the data from System Monitor. TypePerf can display the data for any System Monitor counter that is installed on the computer being monitored. The data is written in comma-separated, variable length strings, so you can redirect it to a .txt or .csv file and use a text editor or spreadsheet program to view and format it.

Initially, you might need to use System Monitor to determine the correct names of query elements, but once a valid query is assembled, you can use it repeatedly or add it to logon scripts and other programs.
