Abstract

A method, device and computer program product that monitor situations. The method includes: processing information indicative of an occurrence of events to detect, in response to a current rule set, an occurrence of at least one situation that belongs to a situation set; wherein at least one rule sub-set out of the rule set defines at least one relationship between events that should occur within a lifespan; receiving a request to update a first rule; updating the first rule to provide a first updated rule while continuing to detect an occurrence of situations not affected by the update of the first rule.

Claims

1. A method for situation monitoring, the method comprising:

processing, by a complex event processing engine, information indicative of an occurrence of events to detect an occurrence of at least one situation that belongs to a situation set;

wherein the detections is responsive to a current rule set;

wherein at least one rule sub-set out of the rule set defines at least one relationship between events that should occur within a lifespan;

receiving a request to update a first rule;

updating the first rule to provide a first updated rule while continuing to detect, by the complex event processing engine, an occurrence of situations not affected by the update of the first rule.

2. The method according to claim 1 wherein the receiving is followed by validating the request and rejecting a non-valid request.

3. The method according to claim 1 wherein the updating is followed by restarting a detection of each situation that is defined by a situation definition that comprises the first updated rule.

4. The method according to claim 1 wherein the updating is followed by restarting a detection of a situation out of the situation set if a detection of an occurrence of that situation is affected by the update of the first rule.

5. The method according to claim 1 wherein the updating is followed by determining if previously detected events correspond to the first updated rule, and selectively re-starting the detection of at least one situation in response to the determination.

6. The method according to claim 1 wherein the updating is followed by detecting an occurrence of at least one situation according to the updated first rule and concurrently detecting an occurrence of at least one situation according to the first rule.
