NAME

App::Standby::Service - Service Plugin baseclass

ADDING A NEW SERVICE

First of all there are two kinds of services: Simple HTTP endpoints and complex plugins.

The simple HTTP plugins just receive the whole queue in as JSON encoded array. Those only need to subclass App::Standby::Service::HTTP and provide an implementation for _init_endpoints. Have a look at the simple example.

All other services will need to subclass App::Standby::Service and implement an update() method. Have a look at App::Standby::Service::Pingom for an example.

The method _config_values helps with getting values to known keys from the config table. A service plugin MUST always prepend its name to the key to allow for multiple instances of one plugin registered at the same time.
