Abstract:
1. A system for detecting artificially generated load on a search system, the system including a processor and a computer storage medium and comprising: one or more processors capable of implementing: (1) a load monitoring component for monitoring a current load for comparison with an expected load, wherein load comprises search queries received from users per unit time; (2) an abnormality detection component for detecting an abnormal load, wherein the current load is compared to the expected load, and wherein an abnormality is detected when the current load exceeds the expected load by a predetermined threshold; (3) a cache hit ratio component for detecting and analyzing a cache hit ratio, wherein the cache hit ratio is a ratio of a number of search queries for which the search system returns results from a search system cache to a number of search queries for which the search system returns results from an index system; and (4) an analysis component for determining the detected abnormal load includes an artificial load based on the cache hit ratio.
