How to configure Zabbix to monitor Tomcat?

Question

Monitoring

Good afternoon!
Please help with setting up tomcat monitoring on zabbix.
Given:
Zabbix-server ip xxxx
server with tomcat ip yyyy
What I did:
zabbix-java-gateway is installed on the zabbix server (I didn’t change anything in its config file)
in the zabbix.conf config - javagateway=127.0.0.1 javagatewayport=10033
On the server where tomcat (ip - yyyy) added CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=7777 -Dcom.sun.management.jmxremote.ssl=false -Djava to catalina.sh .rmi.server.hostname=yyyy"
In the zabbix web-face I add a server where jmx interface yyyy port 7777 and JMX does not turn green.
Where could be the problem??

Answer 1

1. Create remote.users and remote.acl files, for example, in the /conf folder
   
2. remote.user contains the user password, in the format: usename strontpassword
   
3. remote.acl contains JMX permissions e.g. username readwrite
   
4. in catalina.sh write:
   CATALINA_OPTS="$CATALINA_OPTS \
   -Dcom.sun.management.jmxremote.password.file=/<path to tomcat>/conf/remote.users \
   -Dcom.sun.management.jmxremote.access.file =/<path to tomcat>/conf/remote.acl \
   -Dcom.sun.management.jmxremote \
   -Dcom.sun.management.jmxremote.port=7777 \
   -Dcom.sun.management.jmxremote.ssl=false \
   - djava.rmi.server.hostname=yyyy"
   Personally, without a user, JMX also did not rise for me. In Zabbix, when creating items, specify the login and password for JMX. Look at the templates here: https://www.zabbix.com/integrations/tomcat
   In general, if something does not take off, you should first look at the zabbix-server and zabbix-java-gateway logs :)

If I remember correctly, there is nothing super complicated there - a template is set, configured and everything works.
