Zabbix monitors tomcat through JMX

In server.zabbix.com, we have added the --enabled-java option and arranged the java environment when compiling, so we will not describe too much

1. Configure the java gateway

cd /usr/local/zabbix/sbin/zabbix_java/

vim settings.sh

The configuration is as follows:

Second, modify the zabbix server configuration file

vim /usr/local/zabbix/etc/zabbix_server.conf

// add end line

The configuration is as follows:

Restart zabbix_server and zabbix_agentd after completion

killall -9 zabbix_server

killall -9 zabbix_agentd

zabbix_agentd

zabbix_server

sh /usr/local/zabbix/sbin/zabbix_java/startup.sh //start configuration script

netstat -anpt | grab 10052

// Check port 10052 successfully started

3. Install tomcat

(1) Download and install the tomcat software package

java -version

javac -version

which java

tar xf apache-tomcat-8.5.16.tar.gz

mv apache-tomcat-8.5.16 /usr/local/tomcat/

(2) Modify the tomcat startup script

vim /usr/local/tomcat/bin/catalina.sh

The configuration is as follows:

explain:

CATALINA_OPTS="$CATALINA_OPTS

-Dcom.sun.management.jmxremote ## Enable remote monitoring

JMX-Dcom.sun.management.jmxremote.port=12345 #jmx remote port, Zabbix must be consistent when added

-Dcom.sun.management.jmxremote.authenticate=false #Do not enable user password authentication

-Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=192.168.59.137" #Run tomcat service IP (do not fill in wrong)

(3) Start tomcat

/usr/local/tomcat/bin/catalina.sh start

netstat -anpt | grab LIST | grab java

Mainly depends on whether port 12345 is enabled
