Resolution: Rejected
The monitoring classes are part of the JRE in JDK1.5, e.g. Sun code.
Monitoring Only Sends Single Notification Message
-------------------------------------------------
Key: JBJMX-98
URL:
https://jira.jboss.org/jira/browse/JBJMX-98
Project: JBoss JMX
Issue Type: Bug
Affects Versions: JBossAS-4.0.0
Environment: Windows 2000, Sun JDK 1.5, Single CPU 1GB RAM
Reporter: Brian Husted
I have configured a threshold monitoring mbean to monitor the QueueDepth on a JMS queue.
When the QueueDepth is greater than 500, I have registered to receive a notification on
the ConsoleAlterListener.
The problem is that only one notification is sent when the QueueDepth exceeds 500. The
depth will go back down below 500 and minutes later it will again exceed 500 but a
notificaiton is NOT sent. I did notice that if I click the clear-all-alerts button on the
web-console then the notification will be sent again but only if you clear it each time it
appears.
Below is my config for the threshold monitor. I have tested this with the
ConsoleAlertMonitor and a custom MBeanListener and I experience the same problem with
either configuration.
[Code]
