Monitor JMX memory running on the server

Use JDK jconsole to monitor JMX

 

First, set the monitoring object port configuration Catalina. Sh

# Vi/usr/tomcat/bin/Catalina. Sh

Note:/usr/tomcat/bin/Catalina. Sh is the bin directory of the Tomcat directory (in Linux)

Add content before # OS specific support. $ VaR _ must _ be set to either true or false.

 

# Java_opts set memory

Java_opts = "-xms2g-xmx2g-XX: + useconcmarksweepgc-XX: + cmsincrementalmode-XX: newsize = 512 M-XX: maxpermsize = 256 m"

 

# Set JMX port information for catalina_opts

Catalina_opts = "$ catalina_opts-DCOM. Sun. Management. jmxremote-DCOM. Sun. Management. jmxremote. Port = 9004"

Catalina_opts = "$ catalina_opts-DCOM. Sun. Management. jmxremote. SSL = false-DCOM. Sun. Management. jmxremote. Authenticate = false"

 

Then, start the corresponding Tomcat and view the port running

[[Email protected] ~] # Netstat-antp | grep 9004
TCP 0 0: 9004: * Listen 2288/Java

Finally, verify that the local JDK has been installed.

Open CMD and run the following command to enter the Directory: C: \ Program Files \ Java \ jdk1.6.0 _ 43 \ bin.

C: \ Users \ shuaiqi> Cd/d c: \ Program Files \ Java \ jdk1.6.0 _ 43 \ bin

Execute the jconsole.exe File

C: \ Program Files \ Java \ jdk1.6.0 _ 43 \ bin> jconsole.exe

Now the JMX connection is enabled.

You can select local and remote processes.

Enter the remote address:

Note: you do not need to enter the user and password because the user and password are not required in the above settings. You can set it if necessary.
