Realtime notification of ThreadPool logFull 2006-11-17 - By jwboring
Back
I need to be notified when ever a Tomcat v5.5 server is over the threadpool
limit. I am already monitoring log4j log messages but the logFull message
appears to me to be a System.out log, by-passing log4j (catalina.out text
shown below).
Nov 17, 2006 12:08:25 PM org.apache.tomcat.util.threads.ThreadPool  logFull
SEVERE: All threads (10) are currently busy, waiting. Increase maxThreads
If my above assumption is correct, how can I monitor ThreadPool logFull
messages without reading the catalina.out file and parsing? Also, I'm aware
of the ThreadPool mbean and already use JMX to query this mbean to display
it's properties. However, I don't believe this mbean supports JMX
notifications. Of course, I could spawn a thread every X minutes but that
seems dumb. Can I do this with a LifeCycle Listener? Is there a way to get
log4j messages e.g., log.error("logFull SEVERE: All threads ...") from the
ThreadPool object?
