zabbix使用zabbix-java-gateway监控jvm/tomcat性能

JAVA-GATEWAY

 Zabbix本身不支持直接监控Java，在zabbix 1.8以前，只能使用Zapcat来做代理监控，而且要修改源代码，非常麻烦。所有后来为了解决这个监控问题，Zabbix和Java双方应运生成了各自的代理监控程序：zabbix 2.0以后添加了服务进程zabbix-java-gateway；Java有了JMX,全称是Java Management Extensions,即Java管理扩展。

  

双方的工作原理

 技术分享

比如：当Zabbix-Server需要知道java应用程序的某项性能的时候，会启动自身的一个Zabbix-JavaPollers进程去连接Zabbix-JavaGateway请求数据，而ZabbixJavagateway收到请求后使用“JMXmanagementAPI”去查询特定的应用程序，而前提是应用程序这端在开启时需要“-Dcom.sun.management.jmxremote”参数来开启JMX远程查询就行。Java程序会启动自身的一个简单的小程序端口12345向Zabbix-JavaGateway提供请求数据。

  

开始监控部署  

从上面的原理图中我们可以看出，配置Zabbix监控Java应用程序的关键点在于：配置Zabbix-JavaGateway、让Zabbix-Server能够连接Zabbix-JavaGateway、Tomcat开启JVM远程监控功能等

  

1）环境准备

系统环境

[[email protected] ~]# cat /etc/redhat-release 
CentOS Linux release 7.2.1511 (Core) 
[[email protected] ~]# /application/zabbix/sbin/zabbix_server -V
zabbix_server (Zabbix) 3.0.3

特别注意：

编译安装zabbix server需要加上--enable-java以支持jmx监控，如果之前的zabbix server没加，那么请重新编译安装，参考编译参数

./configure --prefix=/application/zabbix-3.0.3 --enable-server --enable-agent --enable-java --enable-ipv6 --with-mysql=/application/mysql-5.5.49/bin/mysql_config  --with-net-snmp --with-libcurl --with-libxml2 --with-openipmi --with-unixodbc --with-openssl

由于要使用到tomcat作为监控示例，所以简单部署一个tomcat环境

[[email protected] tools]# tar xf jdk-8u73-linux-x64.gz
[[email protected] tools]# tar xf apache-tomcat-8.0.36.tar.gz
[[email protected] tools]# mv jdk1.8.0_73 /application/
[[email protected] tools]# ln -s /application/jdk1.8.0_73/ /application/jdk
[[email protected] tools]# sed -i.ori ‘$a export JAVA_HOME=/application/jdk\nexport PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH\nexport CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar‘ /etc/profile
[[email protected] tools]# source /etc/profile
[[email protected] tools]# java -version
java version "1.8.0_73"
Java(TM) SE Runtime Environment (build 1.8.0_73-b02)
Java HotSpot(TM) 64-Bit Server VM (build 25.73-b02, mixed mode)
[[email protected] ~]# ln -s /application/apache-tomcat-8.0.36/ tomcat
[[email protected] ~]# echo ‘export TOMCAT_HOME=/application/tomcat‘>>/etc/profile
[[email protected] ~]# source /etc/profile
[[email protected] ~]# chown -R root.root /application/jdk/ /application/tomcat/
[[email protected] ~]# tail -4 /etc/profile
export JAVA_HOME=/application/jdk
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar
export TOMCAT_HOME=/application/tomcat
[[email protected] ~]# /application/tomcat/bin/startup.sh #开启tomcat
[[email protected] ~]# lsof -i:8080
COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
java    40859 root   47u  IPv6  71038      0t0  TCP *:webcache (LISTEN)

   

2）安装软件

yum install -y java java-devel zabbix-java-gateway

  

3）配置zabbix_java_gateway端口10052

[[email protected] zabbix]# vim /etc/zabbix/zabbix_java_gateway.conf
#zabbix_java_gateway配置文件里有默认端口等设置，这里我们保持默认即可
[[email protected] zabbix]# systemctl start zabbix-java-gateway.service
[[email protected] ~]# lsof -i:10052
USER   FD   TYPE  DEVICE SIZE/OFF NODE NAME
java    92222 root   11u  IPv6 1360516      0t0  TCP *:10052 (LISTEN)

   

4）配置zabbix-server访问gateway

[[email protected] ~]# vim /application/zabbix/etc/zabbix_server.conf
JavaGateway=172.16.2.150 #gateway地址
StartJavaPollers=5  #预启动进程轮训个数
[[email protected] ~]# systemctl restart zabbix_server.service

   

5）开启JMX远程监控

[[email protected] application]# vim /application/tomcat/bin/catalina.sh #tomcat的远程调用脚本
CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote #开启远程监控
  -Dcom.sun.management.jmxremote.port=12345 #远程监控端口
  -Dcom.sun.management.jmxremote.ssl=false #远程ssl验证为false
  -Dcom.sun.management.jmxremote.authenticate=false #关闭权限认证
  -Djava.rmi.server.hostname=172.16.2.150" #提供数据的的主机地址（由于我是用的一台机器，所以IP相同，如果是生产环境不同的机器，这个地址是部署了tomcat的主机地址）
[[email protected] application]# /application/tomcat/bin/shutdown.sh
[[email protected] application]# /application/tomcat/bin/startup.sh
[[email protected] application]# lsof -i:12345 #JVM监听端口
COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
java    41062 root   20u  IPv6  72478      0t0  TCP *:ddi-tcp-1 (LISTEN)

注意：

如果端口起不来，看日志

[[email protected] logs]# tail /application/tomcat/logs/catalina.out
…
Error: Exception thrown by the agent : java.net.MalformedURLException: Local host name unknown: java.net.UnknownHostException: linux-node1.lichengbing.cn: linux-node1.lichengbing.cn: unknown error

添加主机名解析解决

[[email protected] logs]# cat /etc/hosts
172.16.2.150 linux-node1.lichengbing.cn

  

6）此时我们就也可以使用windowsJava工具JConsole测试（提前安装好java）
