classmethod load(context, watch_name=None, watch=None)[source]

Load the watchrule object.

The object can be loaded either from the DB by name or from an existing DB object.

rule_actions(new_state)[source]
run_rule()[source]
set_watch_state(state)[source]

Temporarily set the watch state.

Returns:list of functions to be scheduled in the stack ThreadGroup for the specified state.
state_set(state)[source]

Persistently store the watch state.

store()[source]

Store the watchrule in the database and return its ID.

If self.id is set, we update the existing rule.
