JBoss in Action Q - what debug options exist ....

Recently (today) our application (deployed to JBoss) abruptly stopped responding. During the down time, our login servlet and splash JSPs were never reached and nothing showed up in the log files. A stop-start through the console restored the application but the lack of any log messages bothered me.

So, my question is, what debug and/or monitoring options are available through on the JBoss server? Can they be configured dynamically?

From what you described, a thread dump is your best bet to track down the issue. We cover how to do this in section 14.7.2.

For general monitoring, any tool that can handle MBeans will do. Such tools include the JMX Console (2,3,1), twiddle (2.3.2), Jopr and Embedded Jopr (B.1).
