zabbix 添加jvm监控

1.
zabbix 服务端安装,监控jmx 需要--enable-java

zabbix 客户端不需要 --enable-java

2.zabbix_server端安装jdk

安装jdk

[root@nginx tmp]# tar xf jdk-7u9-linux-x64.tar.gz -C /usr/local/
[root@nginx tmp]# ls /usr/local/jdk1.7.0_09/
bin        jre      README.html                         THIRDPARTYLICENSEREADME.txt
COPYRIGHT  lib      release
db         LICENSE  src.zip
include    man      THIRDPARTYLICENSEREADME-JAVAFX.txt

3.修改zabbix_java相关选项

然后进入到下面的目录下面进行seeting.sh脚本编辑

zabbix:/usr/local/sbin/zabbix_java# pwd
/usr/local/sbin/zabbix_java

zabbix:/usr/local/sbin/zabbix_java# chmod +x settings.sh 

zabbix:/usr/local/sbin/zabbix_java# ls
bin  lib  settings.sh  shutdown.sh  startup.sh

LISTEN_IP="0.0.0.0"
LISTEN_PORT=10052
PID_FILE="/tmp/zabbix_java.pid"
START_POLLERS=5

zabbix:/usr/local/sbin/zabbix_java# ./startup.sh
-------------------
5
zabbix:/usr/local/sbin/zabbix_java# cat startup.sh
#!/bin/bash

cd $(dirname $0)
source settings.sh
echo "-------------------"
echo $START_POLLERS

其中 LISTEN_PORT 和 LISTEN_IP 可以不配置，zabbix_java 会采用默认值。但是 PID_FILE 和 START_POLLERS 必须配置，尤其主意 START_POLLERS，若不配置 zabbix_java 依旧可以启动但是是不工作的。

[root@nginx zabbix_java]#

4.修改配置选项:在zabbix服务端上配置
/etc/zabbix/zabbix_server.conf

添加:
JavaGateway=127.0.0.1  ##这个地址是服务端的地址
JavaGatewayPort=10052
StartJavaPollers=5

zabbix:/usr/local/sbin/zabbix_java# netstat -nap | grep 10052
tcp        0      0 127.0.0.1:54229             127.0.0.1:10052             TIME_WAIT   -

5.启动zabbix_java

找到zabbix_java目录路径，然后执行命令./startup.sh

[root@nginx zabbix-2.2.0]# find / -name zabbix_java
/usr/local/sbin/zabbix_java

tomcat 端配置:

6.调整tomcat端,安装catalina-jmx-remote.jar

wget  http://archive.apache.org/dist/tomcat/tomcat-7/v7.0.8/bin/extras/catalina-jmx-remote.jar

[tomcat@wx01 lib]$ mv /home/tomcat/catalina-jmx-remote.jar .
[tomcat@wx01 lib]$ ls -ltr  catalina-jmx-remote.jar
-rw-rw-r-- 1 tomcat tomcat 9533 Feb  5  2011 catalina-jmx-remote.jar

7.修改catalina.sh文件

修改catalina.sh文件，添加

# -----------------------------------------------------------------------------

JAVA_OPTS='-Xms8192m -Xmx8192m'
export JAVA_HOME=/usr/java/jdk1.8.0_20
CATALINA_OPTS="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=10085"

10085端口自定义,自定义端口号

[tomcat@wx01 bin]$ netstat -na | grep 10085
tcp        0      0 0.0.0.0:10085                0.0.0.0:*                   LISTEN  

8.重启启动tomcat服务和zabbix_agentd服务

9.zabbix服务器端测试是否能正常获取信息
zabbix:/root# java -jar /root/cmdline-jmxclient-0.10.3.jar  - 120.55.118.32:5566 java.lang:type=Memory NonHeapMemoryUsage
