JMX Agent is used to monitor the application of java class

JMX Agent can realize the standardization and application management of various operating systems, system architectures, network protocols and applications.

Server side configuration:

JAVA Gateway needs to be started during zabbix server installation

Zabbix server configuration launches JAVA Gateway

Zabbix server configuration JAVA Gateway/JAVA GatewayPort parameters

Zabbix server configuration StartJavaPollers parameters

Ensuring IP+Port communication between zabbix server and JMX applications

Configuration of the monitored side:

Enable and correctly configure JMX

Data collection process

ZabbixServer initiates a data acquisition request to the Zabbix Java Gateway component. After receiving the request, Java Gateway will initiate a data request to the monitored Java application.

The monitored end receives the request and responds to the corresponding monitoring data. When Zabbix Java Gateway receives the data, it returns it to ZabbixServer.

Check whether JavaGateway [root @ localhost ~] # rpm-qa is installed on the server | grep zabbix

If it is not installed Installation command: yum-y install zabbix-java-gateway-4.2.6-1.el7.x86_64 can also use yum to find the installation package yum search zabbix to change the configuration file of zabbixJavaGateway [root@localhost zabbix] # grep ^ [Amurz] / etc/zabbix/zabbix_java_gateway.conf LISTEN_IP= "0.0.0.0" LISTEN_PORT=10052PID_FILE= "/ var/run/zabbix/zabbix_java.pid" START_POLLERS=5TIMEOUT=3JAVA_OPTIONS= "$JAVA_OPTIONS-Dcom.sun .management.jmxremote-Dcom.sun.management.jmxremote.port=12345 launch zabbix JavaGateway [root@localhost ~] # systemctl start zabbix-java-gateway.service [root@localhost ~] # systemctl status zabbix-java-gateway.service ● zabbix-java-gateway.service-Zabbix JavaGateway Loaded: loaded (/ usr/lib/systemd/system/zabbix-java-gateway.service) Disabled; vendor preset: disabled) Active: active (running) since II 2019-09-17 21:00:41 CST 10s ago Process: 24955 ExecStart=/usr/sbin/zabbix_java_gateway (code=exited, status=0/SUCCESS) Main PID: 24959 (java) CGroup: / system.slice/zabbix-java-gateway.service └─ 24959 java- server-Dcom.sun.management.jmxremote-Dcom.sun.management.jmxremot...9 17 21:00:39 localhost.localdomain systemd [1]: Starting Zabbix Java Gateway...9 17 21:00:41 localhost.localdomain systemd [1]: Started Zabbix Java Gateway.
