This article shows you how to use JMX monitoring in zookeeper. The content is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Uname-r check the linux system version and find that it is centos 7.

CentOS 7.0 uses firewall as the firewall by default, which is changed to iptables firewall here. Firewall:systemctl start firewalld.service# start firewallsystemctl stop firewalld.service# stop firewallsystemctl disable firewalld.service# disable firewall boot

At first, you can ping the virtual machine ip, but the port is not good. The virtual machine jconsole can access the zookeeper cluster, so you can troubleshoot the firewall restrictions on the port and turn off the firewall.

Insert in zoomain

-Djava.rmi.server.hostname=192.168.31.183-Dcom.sun.management.jmxremote.port=8891-Dcom.sun.management.jmxremote.authenticate=false-Dcom.sun.management.jmxremote.ssl=false

I have three zookeeper here to avoid port occupancy

Zookeeper1 configuration

-Djava.rmi.server.hostname=192.168.31.183-Dcom.sun.management.jmxremote.port=8891-Dcom.sun.management.jmxremote.authenticate=false-Dcom.sun.management.jmxremote.ssl=false

Zookeeper2 configuration

-Djava.rmi.server.hostname=192.168.31.183-Dcom.sun.management.jmxremote.port=8892-Dcom.sun.management.jmxremote.authenticate=false-Dcom.sun.management.jmxremote.ssl=false

Zookeeper3 configuration

-Djava.rmi.server.hostname=192.168.31.183-Dcom.sun.management.jmxremote.port=8893-Dcom.sun.management.jmxremote.authenticate=false-Dcom.sun.management.jmxremote.ssl=false

After the configuration is complete, restart the zookeeper service.

In the bin directory of the local jdk installation directory, open jconsole.exe
