Tomcat enabling JMX Remote

Wiki uses JMX for survival monitoring

cat/opt/wiki/work/bin/setenv.sh | grep jmxremote
Catalina_opts= "-dcom.sun.management.jmxremote-dcom.sun.management.jmxremote.port=8410- dcom.sun.management.jmxremote.ssl=false-dcom.sun.management.jmxremote.authenticate=false-duser.timezone=asia/ Shanghai ${catalina_opts} "

For information on how to enabling JMX Remote, refer to the following:

Http://tomcat.apache.org/tomcat-5.5-doc/monitoring.html#Enabling_JMX_Remote

The Sun website includes the list of options and how to configure JMX Remote on Java 5:http://java.sun.com/j2se/1.5.0/docs /guide/management/agent.html.

For quick installation, find here a short installation guide:

ADD the following parameters to your Tomcat startup script:

	set  catalina_opts=-dcom.sun.management.jmxremote     - dcom.sun.management.jmxremote.port=%my.jmx.port%     - dcom.sun.management.jmxremote.ssl=false     - Dcom.sun.management.jmxremote.authenticate=false

1. When you think authorization are a good, add and change this:

   	- dcom.sun.management.jmxremote.authenticate=true     - Dcom.sun.management.jmxremote.password.file=. /conf/jmxremote.password     -dcom.sun.management.jmxremote.access.file=. /conf/jmxremote.access \

2. Edit the access allow file $CATALINA _base/conf/jmxremote.access :

   	Monitorrole Readonlycontrolrole ReadWrite

3. Edit the password file $CATALINA _base/conf/jmxremote.password :

   	Monitorrole Tomcatcontrolrole Tomcat

   Tip: Password File must is readonly and not accessible from every other user! Remove all and users under Windows to access the this file.

Note: The JSR Jmx-adaptor opens a second data protocol port. That was a problem when you had installed a local firewall. However, there is at least one possible workaround:using a custom jmxconnectorserver.

Start a JMX Adaptor with fix data port are supported with Tomcat 5.5.25 SRC release:

	<Server ...>...< Listener classname= "Org.apache.catalina.mbeans.JMXAdaptorLifecycleListener"            namingport= "8083"  port= "8084"  host= "Myhost" &NBSP;/>&NBSP;&NBSP; </server>

You can use all JMX System Properties (com.sun.management.jmxremote.xxx) to configure the adaptor:-)
At your remote Jconsole call the JMX adaptor with following command
Jconsole Service:jmx:rmi://myhost:8084/jndi/rmi://myhost:8083/server

Activate JMX mx4j Http Adaptor with Java 1.4:

2. Install the Tomcat Compat package

4. Install the Mx4j-tools.jar at Common/lib. Please, use the same mx4j version as your Tomcat release

5. Configure a mx4j JMX HTTP Adaptor at your AJP Connector

   	<connector port= "${AJP. PORT} "handler.list=" MX "mx.enabled=" true "mx.httphost=" ${jmx. HOST} "mx.httpport=" ${JMX. PORT} "protocol=" ajp/1.3 "/>

   Tip: With ${AJP. Port}=0 No AJP connection where started.

   Note: mx4j JSR Adaptor to support JDK 1.4 currently not integrated.

7. Start your Tomcat and look with a browser at HTTP://${JMX. Host}:${jmx. PORT}

9. With the MX connector parameter you mx.authMode="basic" mx.authUser="tomcat" mx.authPassword="strange" can control the access!
