Project Description
Ever have a performance problem, but don't know what performance counters to collect or how to analyze them? The PAL (Performance Analysis of Logs) tool is a powerful tool that reads in a performance monitor counter log and analyzes it using known thresholds.

  • An easy to use GUI interface which makes creating batch files for the PAL.ps1 script.
  • A GUI editor for creating or editing your own threshold files.
  • Creates an HTML based report for ease of copy/pasting into other applications.
  • Analyzes performance counter logs for thresholds using thresholds that change their criteria based on the computer's role or hardware specs.
