Extensive documentation can be found on https://hexdocs.pm/crow.\n\nUsing Crow, you can set up informative graphs about your Elixir applications\nquickly and easily. For instance, this is what the `CrowPlugins.BEAM.Memory`\nand `CrowPlugins.BEAM.IO` plugins generate for you to view in Munin:\n\n![daily \u0026 weekly memory usage \u0026 bytes via port in / out\ngraphs](./static/crow_plugins_graph.png)\n\n## Overview\n\nCrow has an acceptor process that deals with listening to\nconnections on a configured port (defaulting to `4949`). On connection, a\nworker is spawned that speaks the [munin master-node data exchange\nprotocol](http://guide.munin-monitoring.org/en/latest/master/network-protocol.html#network-protocol).\n\nThe worker provides the connected peer with access to plugins, plugins are\nmodules that implement the `Crow.Plugin` behaviour. The\n[`crow_plugins`](https://github.com/jchristgit/crow_plugins) repository contains\na couple of plugins that can be used in monitoring the BEAM itself.\n\n## Installation\n\nYou can install `crow` by adding it to your `mix.exs`:\n\n```elixir\ndef deps do\n  [\n    {:crow, \"~\u003e 0.1\"}\n  ]\nend\n```\n\nAfter adding Crow to your Elixir app, register the server running it in your\nMunin master configuration. For instance, if you have an Elixir app with Crow\nlistening on port `4949`, the following configuration would suffice (assuming\nyou also installed a munin node):\n\n```ini\n[myapp]\n    address 127.0.0.1\n```\n\nHowever, it's recommended to run Crow alongside a regular Munin node, which\ntends to listen on `4949` itself. Therefore, assuming you want to have\ninformation from both your server and the app, you could use a configuration\nlike the following:\n\n```ini\n[example.com]\n    address 127.0.0.1\n\n[example.com;myapp]\n    address 127.0.0.1\n    port    4950\n```\n\n\u003c!-- vim: set textwidth=80 sw=2 ts=2: --\u003e\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjchristgit%2Fcrow","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjchristgit%2Fcrow","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjchristgit%2Fcrow/lists"}
