Abstract
A system and method are provided for detecting artificially generated load on a search system. The system may include a load monitoring component for monitoring a current load for comparison with an expected load. The system may additionally include an abnormality detection component for detecting an abnormality when the monitored load exceeds an expected amount by a predetermined threshold. The system may further include an analysis component for determining if the monitored load is an artificial load.
Claims20
A system for detecting artificially generated load on a search system, the system comprising:
- a load monitoring component for monitoring a current load for comparison with an expected load;
- an abnormality detection component for detecting an abnormality when the current load exceeds the expected load by a predetermined threshold;
- and
- an analysis component for determining if the current load includes an artificial load.
A method for detecting artificially generated load on a search system, the method comprising:
- monitoring a current load on a search system;
- comparing the current load with an expected load;
- detecting an abnormality if the current load exceeds the expected load by a predetermined threshold;
- and
- analyzing the abnormal load to determine if the abnormal load is artificial or natural.
A method for determining if a detected load on a search system is natural or artificial, the method comprising:
- determining a current cache hit ratio;
- comparing the current cache hit ratio to an average cache hit ratio;
- and
- determining that the detected load is artificial if the current cache hit ratio is sufficiently below the average cache hit ratio.
