Overview

The Collector is a simple thread that polls various system-level metrics that are not pushed to the Processor from third-party applications.

The Collector features a very simple DSL to implement custom collector plugins. Simply create a file with a .rb file extension and a collect block:

collect do
  File.open('/proc/foobar').each do |line|
    parse(line)
  end
end

Copy this plugin to a location of your choice and set collector.load_paths in your configuration to point to the containing directory.

The collector thread will then call this plugin once per resolution tick. See configuration for details.

Custom intervals can also be specified for high frequency sampling:

collect(0.3) do
  File.open('/proc/foobar').each do |line|
    parse(line)
  end
end
