Zabbix 通过 JMX 监控 tomcat

在server.zabbix.com中我们在编译时已经添加--enabled-java选项并布置好了java环境

配置java网关

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

ls

bin  lib  settings.sh  shutdown.sh  startup.sh

vim settings.sh

9 LISTEN_IP="0.0.0.0"

17 LISTEN_PORT=10052

27 PID_FILE="/tmp/zabbix_java.pid"

35 START_POLLERS=5

cd

vim /usr/local/zabbix/etc/zabbix_server.conf   //末行追加

JavaGateway=127.0.0.1

JavaGatewayPort=10052

StartJavaPollers=5

bash /usr/local/zabbix/sbin/zabbix_java/startup.sh    //启动配置脚本

netstat -anpt | grep 10052      //查看10052端口装态 启动成功

tcp6       0      0 :::10052                :::*                    LISTEN      19451/java 

安装tomcat

java -version

java version "1.8.0_91"

Java(TM) SE Runtime Environment (build 1.8.0_91-b14)

Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)

javac -version

javac 1.8.0_91

which java

/usr/local/java/bin/java

tar xf apache-tomcat-8.5.16.tar.gz

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

修改tomcat启动脚本

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

#!/bin/sh     //添加如下信息

CATALINA_OPTS="$CATALINA_OPTS

-Dcom.sun.management.jmxremote

-Dcom.sun.management.jmxremote.port=12345

-Dcom.sun.management.jmxremote.authenticate=false

-Dcom.sun.management.jmxremote.ssl=false

-Djava.rmi.server.hostname=192.168.200.123"

 

解释

CATALINA_OPTS="$CATALINA_OPTS

-Dcom.sun.management.jmxremote # #启用远程监控

JMX-Dcom.sun.management.jmxremote.port=12345 #jmx远程端口,Zabbix添加时必须一致

-Dcom.sun.management.jmxremote.authenticate=false #不开启用户密码认证

-Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=192.168.200.123" #运行tomcat服务IP(不要填写错了)

启动tomcat

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

netstat -anpt | grep LISTEN | grep java

tcp6       0      0 :::1028                 :::*                    LISTEN      31310/java         

tcp6       0      0 :::10052                :::*                    LISTEN      19451/java         

tcp6       0      0 127.0.0.1:8005          :::*                    LISTEN      31310/java         

tcp6       0      0 :::8009                 :::*                    LISTEN      31310/java         

tcp6       0      0 :::17806                :::*                    LISTEN      31310/java         

tcp6       0      0 :::8080                 :::*                    LISTEN      31310/java         

tcp6       0      0 :::12345                :::*                    LISTEN      31310/java  

Zabbix-web端配置

添加JMX信息

 

导入模板

 

 

 

 

为server.zabix.com添加模板

 

 

 

 

等待一会效果如下（1-2分钟）

如变红色 查看在tomcat的启动脚本中配置的端口后是否启动 为下面状态

[root@agent ~]# netstat -antp | grep java

tcp6       0      0 :::21406                :::*                    LISTEN      11385/java         

tcp6       0      0 127.0.0.1:8005          :::*                    LISTEN      11385/java         

tcp6       0      0 :::8009                 :::*                    LISTEN      11385/java         

tcp6       0      0 :::8080                 :::*                    LISTEN      11385/java         

tcp6       0      0 :::25464                :::*                    LISTEN      11385/java         

tcp6       0      0 :::12345                :::*                    LISTEN      11385/java         

tcp6       0      0 192.168.200.112:12345   192.168.200.111:39274   ESTABLISHED 11385/java          

tcp6       0      0 192.168.200.112:21406   192.168.200.111:26844   ESTABLISHED 11385/java         

tcp6       0      0 192.168.200.112:21406   192.168.200.111:26846   ESTABLISHED 11385/java

如果没有脚本中配置的端口重启tomcat即可 

查看tomcat出图情况

 

其他JVM项出垃圾回收均可出图
