Zabbix 3.2 通过JMX监控Tomcat性能状态

一. 服务端(zabbix_server)配置

1.由于zabbix_java_gateway插件需要依赖于jdk，故首先安装jdk

#tar -zxf jdk-7u80-linux-x64.tar.gz
#mv /root/jdk-7u80-linux /usr/local/java
#vi /etc/profile 添加如下内容:
　　   export JAVA_HOME=/usr/local/java
      export PATH=$JAVA_HOME/bin:$PATH
      export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
#java -version
java version "1.7.0_80"
Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)

2.下载并安装对应zabbix版本的zabbix-java-gateway插件

#rpm -Uvh http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-java-gateway-3.2.4-1.el7.x86_64.rpm

3. 由于此次zabbix_server与java_gateway在同一台机器上，故IP设置均为本地,编辑/etc/zabbix/zabbix_java_gateway.conf

# This is a configuration file for Zabbix Java Gateway.
# It is sourced by startup.sh and shutdown.sh scripts.

### Option: zabbix.listenIP
#       IP address to listen on. 
#
# Mandatory: no
# Default:
LISTEN_IP="127.0.0.1"   #设置IP地址

### Option: zabbix.listenPort
#  Port to listen on. 
#
# Mandatory: no
# Range: 1024-32767
# Default:
LISTEN_PORT=10052   #设置监听端口

### Option: zabbix.pidFile
#       Name of PID file.
#       If omitted, Zabbix Java Gateway is started as a console application.
#
# Mandatory: no
# Default:
# PID_FILE=

PID_FILE="/var/run/zabbix/zabbix_java.pid"

### Option: zabbix.startPollers
#       Number of worker threads to start.
#
# Mandatory: no
# Range: 1-1000
# Default:
START_POLLERS=5    #设置工作线程

### Option: zabbix.timeout
#       How long to wait for network operations.
#
# Mandatory: no
# Range: 1-30
# Default:
# TIMEOUT=3

TIMEOUT=3

4.查看zabbix-java-gateway安装后的启动脚本/配置文件位置等

# rpm -ql zabbix-java-gateway-3.2.4-1.el7.x86_64

/etc/zabbix/zabbix_java_gateway.conf
/etc/zabbix/zabbix_java_gateway_logback.xml
/usr/lib/systemd/system/zabbix-java-gateway.service
/usr/lib/tmpfiles.d/zabbix-java-gateway.conf
/usr/sbin/zabbix_java_gateway                   #启动脚本
/usr/share/doc/zabbix-java-gateway-3.2.4

/usr/share/zabbix-java-gateway/lib/slf4j-api-1.6.1.jar
/var/log/zabbix
/var/run/zabbix

5.修改/app/zabbix/etc/zabbix_server.conf中java_gateway部分的配置项

### Option: JavaGateway
#       IP address (or hostname) of Zabbix Java gateway.
#       Only required if Java pollers are started.
#
# Mandatory: no
# Default:
JavaGateway=127.0.0.1              #配置java gateway的机器IP
### Option: JavaGatewayPort
#       Port that Zabbix Java gateway listens on.
#
# Mandatory: no
# Range: 1024-32767
# Default:
JavaGatewayPort=10052                #java gateway监听端口
### Option: StartJavaPollers
#       Number of pre-forked instances of Java pollers.
#
# Mandatory: no
# Range: 0-1000
# Default:
StartJavaPollers=5

6.服务端配置后可直接启动java gateway

#sh /usr/sbin/zabbix_java_gateway
#netstat -antlp | grep :10052

二. 客户端(Tomcat)配置

1.编辑/usr/local/tomcat/bin/catalina.sh 添加如下内容:

CATALINA_OPTS="$CATALINA_OPTS
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=12345          #JMX端口
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-Djava.rmi.server.hostname=<tomcat server IP>"     #Tomcat Server IP

2.重启Tomcat

#/usr/local/tomcat/bin/shutdown.sh
#/usr/local/tomcat/bin/startup.sh

3.测试java gataway 通过客户端工具jmxcmd，有正常输出即为配置正确

#java -jar cmdline-jmxclient-0.10.3.jar - 172.16.3.126:12345 java.lang:type=Memory NonHeapMemoryUsage

07/19/2017 10:11:16 +0800 org.archive.jmx.Client NonHeapMemoryUsage: 
committed: 185073664
init: 2555904
max: -1
used: 179324752

三. zabbix配置

1.由于使用系统默认自带模板Template JMX Generic/Template JMX Tomcat会出现很多item项无数据中，经分析后发现默认定义的application/item项与实际tomcat部署的版本中关于Catalina MBean Name存在差异,故需要进行修改

2.如何查看不同Tomcat版本中支持的MBean Object Name以及属性值

　　①. 可通过使用jconsole远程连接jmx接口，查看对应的MBean Name/Attribute值
