.NET Monitor - pprof API

This is a small wrapper around the dotnet-monitor tool which converts the .nettrace profiling information it outputs into the pprof format.

It currently only works with CPU profiling, though additional profiling may be added in the future.

Testing

A docker-compose.yml file is included which can be used to launch this tool, along with Grafana and Grafana Phlare. To run it locally, you will need to launch dotnet-monitor and the program you wish to collect profiling information from.

  1. Launch dotnet-monitor with the following command...

    dotnet-monitor collect --no-auth --urls http://localhost:52323

  2. Update the environment variable Controller__DotnetMonitorUrl in docker-compose.yml to point dotnet-monitor-pprof-api to dotnet-monitor. Make sure to update the pid query parameter to point to the ID of the process you want to profile.

  3. Run docker-compose up and then navigate to http://localhost:3000
