PerfAgent

perf_agent is a plug that will record timing and status codes of the connections in the Phoenix framework and send the data to Perf. We then run analytics on that data to generate metrics and alerts.

Right now perf is in private beta but if you're interested in an API key, feel free to email us at hi@perf.sh

Installation

• Add the agent to your list of dependencies in mix.exs via Hex

  def deps do
    [{:perf_agent, "~> 0.1.7"}]
  end

  • Run mix deps.get in your Terminal to install all dependencies

• Ensure perf_agent is started before your application

  def application do
    [applications: [:perf_agent]]
  end

• Add your Perf API Key to your config.exs

  config :perf_agent, api_key: "PERF_API_KEY"

• Add the plug to a pipeline in your router

  defmodule MyApp.Router do
    use MyApp.Web, :router
  
    pipeline :api do
      plug :accepts, ["json"]
      plug PerfAgent.Plug.Phoenix
    end
  
    scope "/api/v1", MyApp do
        pipe_through :api
    end
  
  end

  • In this example we've added it to an API pipeline
