Testing Adaptive Metric Thresholds
Because adaptive metric thresholds utilize statistical sampling of data over time, the accuracy of the thresholds will rely on the quantity and quality of the data collected. Hence, a sufficient amount of metric data needs to have been collected in order for the thresholds to be valid. To verify whether enough data has been collected for metrics registered with adaptive thresholds, use the Test Data Fitness function.
- From the Registered Adaptive Metrics region, click Test Data Fitness.
Enterprise Manager evaluates the adaptive threshold metrics and then displays the results in the Test Metrics window.
If there is sufficient data collected to compute the adaptive threshold, a green check appears in the results column. A red 'x' appears in the results column if there is insufficient data collected. To resolve this situation, you can use a longer accumulating trailing data window. Additionally, you can have metric data collected more frequently.
