摘要： Dynamic filtering methods, systems and computer program products are provided for network performance test results which may apply network troubleshooting expertise and knowledge of network topology to select and display test results in a manner which may facilitate analysis of those results by IT staffs. In a further aspect of the present invention, a severity index is provided which may be generated based on exception events from a plurality of network performance measurements, for example, response time, throughput and availability, which measurements are generated from test results obtained from agents located on various devices on a computer network. The test results may be obtained from either passive application monitor agents or active network test agents. In another aspect of the present invention, the exception events may be detected based on automatically generated threshold criteria which may be provided user selectable sensitivity and may be based on a specified percentage criteria relative to baseline performance results. In a further aspect of the present invention, the test results may be stored using data buckets with the number of data buckets and/or the range of each of the data buckets being selected to provide a desired overall range and granularity for each of the plurality of network performance measurement types. The range (width) of some of the data buckets may be narrower than others to provide greater resolution in a region of interest.
