Warning The real data and tracing does not work. You can run it to see fake data, but we are tired, we had both weekend full of family stuff to do....
So honestly, it is broken. That is life. Will probably fix in the future cause i need it, but not now
Oh and there are no tests. We simply had too much family needs during weekends. Life is life.
Orion is a Dynamic Distributed Profiler. It allows you to profile any function in an erlang cluster and get back an histogram representing the profile of the function calls across the whole cluster.
It is meant to be used as a library in part of your existing application.
- Can show a graph of fake or real data
- Can change the function traced to a new one
- Can get trace data in a distributed way
- More to come !
- Be useable in any BEAM language. This may happen in the future but for now we depend on dog_sketch which is in elixir
- separate frontend and data collection library. That may come in the future, but no time for it at spawnfest
You need elixir 1.12 and OTP 24.
Orion is a phoenix liveview application for the frontend.
To start your Phoenix server:
- Install dependencies with
mix deps.get
Test can be run with mix test. We try to keep everything in the elixir side tested fairly completely
If you want to see it in action
- Install Node.js dependencies with
yarn install --cwd assetsinside theassetsdirectory - Start Phoenix endpoint with
mix phx.server
Now you can visit localhost:4000 from your browser.
