MetristAgent

Metrist In-Process Agent for the BEAM ecosystem (Erlang, Elixir). This agent will forward timings of intercepted calls to the Metrist Monitoring Agent for further processing.

Interception is currently only implemented for Hackney, which comes with a tracing library. This means that libraries that use Hackney, like HTTPoison, will automatically work.

To use the agent, simply add this module to your application's supervision tree.

Installation

1. Add metrist_agent to your list of dependencies in mix.exs:

def deps do
  [{:metrist_agent, "~> 0.1.0"}]
end

1. Fetch mix dependencies:

$ mix deps.get

1. Add Metrist.Agent to your application's supervision tree in application.ex:

def start(_type, _args) do
  children = [
    Metrist.Agent,
  ]

  ...

This will start the Metrist Agent and hook into hackney to begin listening for network requests.
