Dallas

This is a simple monitoring tool most fitting for business monitoring.

It works as a platform inside a phoenix application to periodically run your instruments and display then on the screen.

Installation

1. If available in Hex, the package can be installed by adding dallas to your list of dependencies in mix.exs:

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

2. Add dallas_dashboard "/dallas" to your router.ex file.

Example:

  scope "/", ExampleWeb do
    pipe_through :browser

    get "/", PageController, :home

    dallas_dashboard "/dallas"
  end

3. Write your own instruments

defmodule YourProject.Instruments.MyInstrument do
  use Dallas.Instrument, queue: :default

  alias Dallas.Measurement

  def measure do
    # do whatever you want, REALLY, whatever

    # hit APIs, query databases, does not matter

    # just return a list (or one) of Dallas.Measurement structs

    %Measurement{
      path: "Organize/Folders/Whoever/Is/Most/Convenient",
      level: :ok, # or :warning, or :error
      value: "ok"
    }
  end
end
