Hi all, I am working on following two alert generation scenarios,
1. Abnormal response time/ backend time - If an API response time or the backend time lies outside the Xth percentile. 2. Abnormal request counts - Count the number of requests during last minute and check if it lies outside the Xth percentile. Since percentile calculation cannot be done with DAS, it was decided that percentile calculation will be done using a siddhi extension. Extension will keep samples of each api (10000 records per api) and percentile calculation is done to that particular sample. Percentile calculation would happen in a daily basis. Your suggestions are welcome regarding the above approach.
