deleteHistoricalEvents(self, deferred=False, force=False)

source code

Once per day delete events from history table. If force then run the deletion statement regardless of when it was last run (the deletion will still not run if the historyMaxAgeDays setting in the event manager is not greater than zero.) If deferred then we are running in a twisted reactor. Run the deletion script in a non-blocking manner (if it is to be run) and return a deferred (if the deletion script is run.) In all cases return None if the deletion script is not run.

sendPage(self, action, data, clear=None)

source code

Send and event to a pager. Return True if we think page was sent, False otherwise.

sendEmail(self, action, data, clear=None)

source code

Send an event to an email address. Return True if we think the email was sent, False otherwise.
