Abstract
In one aspect, a method includes determining if a rule in a memory of an event-based analysis engine has been used by the event-based analysis engine within a predetermined period of time and moving the rule to a storage device if the rule in the memory of the event-based analysis engine has not been used by the event-based analysis engine within the predetermined period of time.
Claims20
A method, comprising:
- determining if a rule in a memory of an event-based analysis engine has been used by the event-based analysis engine within a predetermined period of time comprising analyzing a last used field of an entry of a rule index;
- and
- moving the rule to a storage device if the rule in the memory of the event-based analysis engine has not been used by the event-based analysis engine within the predetermined period of time.
A method, comprising:
- determining if a rule in a memory of an event-based analysis engine has been used by the event-based analysis engine within a predetermined period of time;
- and
- moving the rule to a storage device if the rule in the memory of the event-based analysis engine has not been used by the event-based analysis engine within the predetermined period of time;
- and
- updating a location field in an entry of a rule index if the rule is moved from the memory to the storage device.
2 more elements
An article comprising:
- a non-transitory machine-readable medium that stores executable instructions to manage a memory of an event-based analysis engine, the instructions causing a machine to:
- determine if a rule in a memory of an event-based analysis engine has been used by the event-based analysis engine within a predetermined period of time comprising instructions causing the machine to analyze a last used field of an entry of a rule index;
- and
- move the rule to a storage device if the rule in the memory of the event-based analysis engine has not been used by the event-based analysis engine within the predetermined period of time.
1 more element
An apparatus, comprising:
- circuitry configured to manage memory of an event-based analysis engine and configured to:
- determine if a rule in a memory of an event-based analysis engine has been used by the event-based analysis engine within a predetermined period of time comprising circuitry configured to analyze a last used field of an entry of a rule index;
- and
- move the rule to a storage device if the rule in the memory of the event-based analysis engine has not been used by the event-based analysis engine within the predetermined period of time,
- wherein the circuitry comprises at least one of a processor, a memory, programmable logic and logic gates.
