ceilometer is heavily depends on python stevedore, you can take a look at stevedore first here

Then just select the right agent base PollAgent, NotificationAgent, CentralAgent ,Evaluator as your base class then check the official example here to write your custom plugins.

Note: you have to register your custom plugin in stevedore entry_point.txt and restart the ceilometer service to make it work.

ceilometer.alarm.evaluator =
    threshold = ceilometer.alarm.evaluator.threshold:ThresholdEvaluator
    combination = ceilometer.alarm.evaluator.combination:CombinationEvaluator

ceilometer.alarm.evaluator_service =
    default = ceilometer.alarm.service:AlarmEvaluationService
    singleton = ceilometer.alarm.service:SingletonAlarmService
    partitioned = ceilometer.alarm.service:PartitionedAlarmService
    # NOTE(sileht): for backward compatibility
    ceilometer.alarm.service.SingletonAlarmService = ceilometer.alarm.service:SingletonAlarmService

Hope that helps!
