Statsd Drivers
Introduction
Statsd has a small driver API to be used for alerting. Multiple drivers can be loaded at the same time to alert in multiple places.
Design
The base class called AlertDriver is used to create new
drivers. These will be supplied self.logger to use for
logging and self.args which contains the arguments supplied
to statsd. Drivers using this need to supply two functions:
- param message
A message with details of the failure
- param device_id
The ID of the device that has failed
- param message
A message with details of the recovered load balancer
- param device_id
The ID of the device that has been recovered
This is the dictionary that maps values for the
--driver <libra_statsd.py --driver>option to a class implementing the driver :py~AlertDriverAPI for the statsd server. After implementing a new driver class, you simply add a new entry to this dictionary to make it a selectable option.
Dummy Driver
This driver is used for simple testing/debugging. It echos the message details into statsd's log file.
Datadog Driver
The Datadog driver uses the Datadog API to send alerts into the Datadog event stream. Alerts are sent as 'ERROR' and repairs as 'SUCCESS'.
HP REST Driver
This sends messages to the HP REST API server to mark nodes as ERROR/ONLINE.
