The collection service. The configuration generator obtains a list of metrics and frequencies from the Varanus configuration store and generates the resulting collectd configuration. Collectd is then started and obtains state via its plugins and pushes state to the Varanus storage service through the use of a bespoke network plugin. Should a use case require additional metrics or an alternative frequency of collection then an event can be dispatched via the coordination service which will in turn be passed to the configuration generator which will update the Collectd configuration as appropriate
