Plugins
The service supports the system of plugins. Plugins must be written in the Python programming language.
Plugin types
There are two sorts of plugins:
On event plugin. The plugin is triggered when an event occurs. The plugin should implement a callback function. This function is called on each event of the corresponding type. The set of event types is defined by the service developers.
Supported event types:
event type
description
monitoring_event
Event contains monitoring points for sending to a custom monitoring system
This plugin demonstrates the sending of a request monitoring data to another service. All monitoring plugins must implement the BaseRequestMonitoringPlugin abstract class.
Background plugin. This sort of plugin is intended for background work.
The background plugin can implement:
custom route
background monitoring of service resources
collaboration of an event plugin and a background plugin (batching monitoring points)
connection to other data sources (Redis, RabbitMQ) and their data processing
This plugin demonstrates background work and implements a route. All background plugins must implement the BaseRequestMonitoringPlugin abstract class.
Enable plugin
If the user implements a plugin, the file with the plugin should be added to the luna_lambda/plugins directory of the service. The plugin filename should be added to the LUNA_LAMBDA_ACTIVE_PLUGINS configuration setting.
