remote monitoring JVM by VisualVM
Hello, I'm tryng to monitor my JVM and so Tomcat HeapMemory usage by remote
access using VisualVM. I configured all, but my client always display an
error message (" Cannoct connect using
service:jmx:rmi:///jndi/rmi://xxx.xxx.xxx.xxx.:8080:jmxrmi").
I added in catalina.sh this Java options:
elif [ "$1" = "start" ] ; then
shift
touch "$CATALINA_BASE"/logs/catalina.out
if [ "$1" = "-security" ] ; then
echo "Using Security Manager"
shift
"$_RUNJAVA" "$LOGGING_CONFIG" $JAVA_OPTS \
#START JMXREMOTE OPTIONS
-Dcom.sun.management.jmxremote.port=8080 \
-Dcom.sun.management.jmxremote.ssl=false \
-Dcom.sun.management.jmxremote.authenticate=true \
#END JMXREMOTE OPTIONS
$CATALINA_OPTS \
-Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS" -classpath "$CLASSPATH" \
-Djava.security.manager \
-Djava.security.policy=="$CATALINA_BASE"/conf/catalina.policy \
-Dcatalina.base="$CATALINA_BASE" \
-Dcatalina.home="$CATALINA_HOME" \
-Djava.io.tmpdir="$CATALINA_TMPDIR" \
org.apache.catalina.startup.Bootstrap "$@" start \
>> "$CATALINA_BASE"/logs/catalina.out 2>&1 &
if [ ! -z "$CATALINA_PID" ]; then
echo $! > $CATALINA_PID
fi
else
"$_RUNJAVA" "$LOGGING_CONFIG" $JAVA_OPTS \
#START JMXREMOTE OPTIONS
-Dcom.sun.management.jmxremote.port=8080 \
-Dcom.sun.management.jmxremote.ssl=false \
-Dcom.sun.management.jmxremote.authenticate=true \
#END JMXREMOTE OPTIONS
$CATALINA_OPTS \
-Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS" -classpath "$CLASSPATH" \
-Dcatalina.base="$CATALINA_BASE" \
-Dcatalina.home="$CATALINA_HOME" \
-Djava.io.tmpdir="$CATALINA_TMPDIR" \
org.apache.catalina.startup.Bootstrap "$@" start \
>> "$CATALINA_BASE"/logs/catalina.out 2>&1 &
if [ ! -z "$CATALINA_PID" ]; then
echo $! > $CATALINA_PID
fi
fi
-----------------------------------------------------------------------------------------------------------------------------------------------
In JRE_Home/management i modified jmxremote.password and added rights
passwords for access roles.
My Tomcat version is 6 and Java1.5. In server.xml I disabled HTTP connector
in order to free use 8080 port for jmx.
I hope you can help me, thanks.

The general building-from-source instructions are here:
http://tomcat.apache.org/tomcat-6.0-doc/building.html
It's easy and fairly quick, but you will need an active internet connection to allow the build script to download jars that Tomcat needs.
I haven't built the new listener yet, but the following should work:
1) Download the Tomcat source and untar/unzip it.
2) Download the two new .java and one .properties files from SVN and place them in:
apache-tomcat-6.0.20-src/java/org/apache/catalina/mbeans
3) Optionally, download the one new and one updated .xml files from SVN and place them in:
apache-tomcat-6.0.20-src/webapps/docs/config
4) Build Tomcat using the ant script that comes with the source download.
You'll need to at least look at the listeners.xml file to see how to configure the new JMX one.
You could also hand-compile the two new .java files, but that's probably harder than just letting ant do it.

Many thanks Chuck, I think this can solve my problem. How can I integrate
this Listener in my production Tom?

Unfortunately, JMX requires an additional, dynamically assigned port, making it difficult to use through a firewall. There is a new listener available for Tomcat that you can configure for a specific secondary port; search the archives for "JMX firewall", or look here:
http://marc.info/?l=tomcat-user&m=123688600013694&w=2

http://marc.info/?l=tomcat-user&m=122216618925359&w=2
AFAIK, the JMX listener has not made it into a Tomcat release, but it should be available from SVN:
http://svn.apache.org/viewvc?rev=699523&view=rev

thanks for all answer, but problem doesn't solve. I tested at last JConsole

I believe the monitor port has to be a different one from the http
request port, so if 8080 is the one your app is listening on, it won't
work for monitoring.

I use 8080 port because it's sure open on server (I used it for tomcat
direct access).

Re: remote monitoring JVM by VisualVM
Posted by trucbinh <tr...@gmail.com>.
Hi,
I think you should add this line
-Djava.rmi.server.hostname=192.168.1.12 like this
-Dcom.sun.management.jmxremote.port=8080 \
-Dcom.sun.management.jmxremote.ssl=false \
-Dcom.sun.management.jmxremote.authenticate=true \
-Djava.rmi.server.hostname=192.168.1.12
192.168.1.12 is your tomcat server address.
Regards,
Binh.
