# @kbn/profiler-cli Profile Kibana while it's running, and open the CPU profile in Speedscope. ## Usage Run a command by either preceding it with the profiler script: `node scripts/profile.js -- $command` Or by piping it in: `$command | node scripts/profile.js` You can also just run it until SIGINT: `node scripts/profile.js` Or with a timeout: `node scripts/profile.js --timeout=10000` ## Examples ### Commands You can copy a curl request from the browser, and place it after the command: `node scripts/profile.js --connections=10 --amount=50 -- curl ...` You can also use stdin for this, for example: `pbpaste | node scripts/profile.js` When using stdin, take into consideration that there is some lag between starting the script and connecting the profiler, so the profiler might miss the first second or so of the running process. You can also use any other command, like `autocannon`, `sleep` or `xargs`. ### SigInt By default, the profiler will run until the process exits:`node scripts/profile.js`. This is useful when you have a long running process running separately and you want to collect the profile over a longer time period. Be aware that this might cause memory issues because the profile will get huge. When you press Cmd+C, the profiler will gracefully exit and first write the profile to disk and open Speedscope. --------- Co-authored-by: kibanamachine <42973632+kibanamachine@users.noreply.github.com> (cherry picked from commit d1493b9) # Conflicts: # .github/CODEOWNERS # src/cli/dev.js
