get_alarm_changes
(alarm_id, on_behalf_of, user=None, project=None, alarm_type=None, severity=None, start_timestamp=None, start_timestamp_op=None, end_timestamp=None, end_timestamp_op=None)[source] Yields list of AlarmChanges describing alarm history
Changes are always sorted in reverse order of occurrence, given the importance of currency.
Segregation for non-administrative users is done on the basis of the on_behalf_of parameter. This allows such users to have visibility on both the changes initiated by themselves directly (generally creation, rule changes, or deletion) and also on those changes initiated on their behalf by the alarming service (state transitions after alarm thresholds are crossed).
Parameters: - alarm_id – ID of alarm to return changes for
- on_behalf_of – ID of tenant to scope changes query (None for administrative user, indicating all projects)
- user – Optional ID of user to return changes for
- project – Optional ID of project to return changes for
- alarm_type – Optional change type
- severity – Optional alarm severity
- start_timestamp – Optional modified timestamp start range
- start_timestamp_op – Optional timestamp start range operation
- end_timestamp – Optional modified timestamp end range
- end_timestamp_op – Optional timestamp end range operation
