The Memory Leak Alert rule sends an alert when a possible memory leak is detected. Detection is done through trend analysis of percent memory usage after garbage collection (GC). An alert is sent when the post-GC memory usage exceeds a user-defined threshold.
The Memory Leak Alert rule includes the following rule-specific settings:
Number of Samples — Specify the number of samples used to determine a moving average value for post-GC memory usage. The default is 10.
User Threshold — Specify the percent memory usage after GC above which an alert is sent. The default is 85.
