In this session, we will look at how to monitor tomcat running on a remote server using Java gateway and JMX.
For this i am using 2 servers.
Zabbix server : Ubuntu EC2 instance
Tomcat server : Ubuntu EC2 instance
Zabbix server is running the Zabbix monitoring tool
Tomcat server is running the Tomcat application.
Make sure your zabbix server is up and running. You will need to install the java gateway on the zabbix server.
"apt install zabbix-java-gateway -y"
Make sure you have port 10050, 10051 and 10052 are open
"netstat -tulpn"
On the remote machine where tomcat is running, create a setenv.sh file in your bin directory and add the following contents.
export CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=12345 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Djava.rmi.server.hostname=100.25.34.154 -Dcom.sun.management.jmxremote.rmi.port=10052 -Djava.net.preferIPv4Stack=true"
Djava.rmi.server.hostname=100.25.34.154 --- change the IP address with the tomcat server IP address.

stop and restart the tomcat server and make sure port number 10050, 12345 and 10052 are open on the remote machine.
