Optopus Graphite Plugin

This plugin utilizes the plugin partials feature of Optopus in order to display graphs on a node page. The included graphs are for systems using collectd -> graphite. It is easy to override how graphs look by changing a few configuration settings. All graphs utilize the DSL provided by the graphite_graph gem. The plugin will read from the list of facts about a node, to generate which graphs make sense. Currently a split is done on the interfaces fact and mounts fact to get a list of interfaces/mount points.

Configuration

To get started, you will likely want to change a few configuration pieces. Below is the full set of configuration options with their defaults:

..rest of your optopus config..
plugins:
    graphite:
        # Change this to your graphite url, example: http://graphite.foo.bar
        base_url: graphite

        # Directory in which your custom graph definitions exist
        graphs_dir: graphs

        # Graph template names, relative to graphs_dir
        graphs:
            interface: interface.graph
            memory: memory.graph
            cpu: cpu.graph
            disk: disk.graph

        # When converting a FQDN in collectd to a graphite value,
        # you usually wind up replacing '.' with a character, set this to
        # the character that you have chosen. 
        hostname_dot_substitution: _

If you want to avoid spamming your view with certain graphs, for example you have a hypervisor node with a ton of bridge interfaces. You can add a configuration option like this:

  graph_excludes:
          interface: /^(br|vnet|lo|virbr)\d+.*$/
