Receivers are the event sinks associated to senlin clusters. When certain events (or alarms) are seen by a monitoring software, the software can notify the senlin clusters of those events (or alarms). When senlin receives those notifications, it can automatically trigger some predefined operations with preset parameter values.
To examine the list of receivers:
When listing receivers, you can specify the sorting option using the sort
parameter and you can do pagination using the limit
and marker
parameters.
Full example: manage receiver
When creating a receiver, you will provide a dictionary with keys and values according to the receiver type referenced.
Optionally, you can specify a metadata
keyword argument that contains some
key-value pairs to be associated with the receiver.

After a receiver is created, most of its properties are immutable. Still, you
can update a receiver’s name
and/or params
.

A receiver can be deleted after creation, provided that it is not referenced by any active clusters. If you attempt to delete a receiver that is still in use, you will get an error message.
