-------------------------------
Summary: Enable GC Log monitoring for important service like
hadoop namenode
Key: EAGLE-97
URL: https://issues.apache.org/jira/browse/EAGLE-97
Project: Eagle
Issue Type: New Feature
Affects Versions: 0.3.0
Reporter: Libin, Sun
Assignee: Libin, Sun
Garbage Collection Monitoring refers to the process of figuring out how JVM is
running GC.
When GC happened, JVM will stop the application from running to execute a GC,
every thread except for the threads needed for the GC will stop their tasks.
The interrupted tasks will resume only after the GC task has completed, the
stop interval is known as "stop-the-world"
For service like namenode, GC will affect the performance, especially full GC,
we should avoid full GC and if full GC happened, we should detected it ASAP and
sent out alert
