The GC Pause Time Alert rule sends an alert when the last garbage collection (GC) pause time is above a user-specified percentage of a user-specified maximum GC pause time.
The GC Pause Time Alert rule includes the following rule-specific settings:
Maximum GC Pause — Specify the maximum acceptable GC pause time in seconds. There is no default.
User Threshold — Specify the percentage of maximum GC pause time above which an alert is sent. The default is 85.
