Question to all, is the JMX Bridge suppose to stop by itself?
For the past few months with I login to the server to check on it, I notice that the JMX Bridge service is stopped so I start it again.
The JMX Bridge is only used if you are monitoring Java Application Servers such as WebSphere, WebLogic, and Apache Tomcat via JMX. If you're not using JMX then this service being stopped should have no effect on polling. However, this service should not be stopping on its own. I recommend looking through the Windows Event logs for any explanation for why the service is stopping. Also, I recommend upgrading to SAM 5.2 SP1 if you haven't already.
