Class JmxFilter

java.lang.Object
  com.atlassian.confluence.jmx.JmxFilter

All Implemented Interfaces:

javax.servlet.Filter

public class JmxFilter
extends java.lang.Object
implements javax.servlet.Filter

This filter will profile incoming requests to measure :

• Total of requests served
• Number of requests currently being served
• Average execution time of the last ten requests
• Number of requests received in the last ten seconds

This adds some overhead to each page request, so it may be worth not adding this filter to the chain by default.
