Class ERXStatisticsStore

java.lang.Object

com.webobjects.appserver.WOStatisticsStore

er.extensions.statistics.ERXStatisticsStore

All Implemented Interfaces:

WOStatisticsStoreMBean, NSKeyValueCoding, NSKeyValueCoding.ErrorHandling, NSKeyValueCodingAdditions

public class ERXStatisticsStore
extends WOStatisticsStore

Enhances the normal stats store with a bunch of useful things which get displayed in the ERXStatisticsPage.

• will dump warning and error messages when a request takes too long, complete with stack traces of all threads.
• logs fatal messages that occurred before a request finished processing.
• fixes an incompatibility with 5.4.
• fixes wrong computation of average session memory

In order to turn on this functionality, you must make this call in your Application null constructor:

this.setStatisticsStore(new ERXStatisticsStore());

Then configure the behavior of this class with the three properties that determine how much it logs and when it logs.

Author:

ak, kieran (Oct 14, 2009) - minor changes to capture thread name in middle of the request (useful for ERXSession.threadName()}
