GC Pauses

The Plumbr Agent monitors all stop-the-world Garbage Collection pauses that take place in the JVM. If the duration of such a pause exceeds a configured threshold, an incident is created. In addition to the time and duration of the pause, a Plumbr incident contains insights that would help reduce either the duration or frequency of the long GC pauses, for example:

  • Plumbr captures a memory snapshots, exposing the most memory-hungry data structures in memory. This allows you to proceed with trimming the most resource-hungry data structures.
  • Allocation and promotion rates exposed by Plumbr, along with the memory consumption in different memory pools will give you clues about the poorly allocated heap structures..
