how to configure JMX monitoring?

[wifi75]

Hello!

Here is a step by step how to set up zabbix-java-gateway and monitor tomcat using built in template
Or alternatively just watch a HowTo video about it https://www.youtube.com/watch?v=h6MlF4ztekg&t=9s

Note that i am doing it on Zabbix 3.0.2 With Centos7

Frontend
1) Configuration->Hosts
You can create a dummy host or just add JMX interface to existing.



2) Add a template click on Templates tab -> Find "Template JMX Generic" click add and update.

That's all we need to do in frontend. Now lets continue in backend. In my situation it is VM with Zabbix Server 3.0.2. installed from packages.

Backend
1) yum install zabbix-java-gateway
2) yum install tomcat
3) edit Tomcat config file /etc/tomcat/tomcat.conf

Be carefull - one extra space can make lots of problems.

# Run tomcat under the Java Security Manager
SECURITY_MANAGER="false"
JAVA_OPTS="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=12345 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false "

4) edit zabbix server config /etc/zabbix/zabbix_server.conf
Count of JavaPollers on server/proxy side should be atliest same as in zabbix_java_gateway.conf

### Option: JavaGateway
# IP address (or hostname) of Zabbix Java gateway.
# Only required if Java pollers are started.
#
# Mandatory: no
# Default:
# JavaGateway=

JavaGateway=127.0.0.1

### Option: JavaGatewayPort
# Port that Zabbix Java gateway listens on.
#
# Mandatory: no
# Range: 1024-32767
# Default:
# JavaGatewayPort=10052


### Option: StartJavaPollers
# Number of pre-forked instances of Java pollers.
#
# Mandatory: no
# Range: 0-1000
# Default:
# StartJavaPollers=0

StartJavaPollers=5

SERVICES
Lets add Tomcat and zabbix-java-gateway to autostart, and start them now.

systemctl enable tomcat
systemctl enable zabbix-java-gateway
systemctl start tomcat
systemctl start zabbix-java-gateway

We need to restart zabbix-server, because we changed the config file
systemctl restart zabbix-server

Now we should see Some Latest Data in frontend under host with Java template!

Hello Dmitry,

I need to monitor apache solr , which is on a different instance than zabbix server.

I followed the document for installation of java-gateway

http://whatizee.blogspot.com/2015/02/zabbix-java-gateway-on-centos-65.html

Could you please guide me through, how to get my jmx enabled for monitoring.

I downloaded the solr template from

Kindly help, I am lost in the middle.

Thanks
