背景说明:
由于zabbix监控使用自带的模版,只能监控主机上只有1个tomcat的场景适合,虽然网上很多朋友都是在每个监控项上面添加一个空格来解决问题。但是个人感觉这种方法还是蛮麻烦的,所以写一篇使用自动发现tomcat并监控。
1,在一台主机上安装2个tomcat,安装完1个tomcat,复制1个即可。复制完之后修改tomcat的端口即可。
https://www.cnblogs.com/lin1/p/5689622.html
2,进入到apache-tomcat1目录,开启jmxport端口。
在被监控的apache-tomcat1应用程序的找到catalina.sh,添加如下内容
CATALINA_OPTS="$CATALINA_OPTS
-Djavax.management.builder.initial=
-Dcom.sun.management.jmxremote=true
-Dcom.sun.management.jmxremote.port=12345
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Djava.rmi.server.hostname=127.0.0.1"
在被监控的apache-tomcat2应用程序的找到catalina.sh,添加如下内容
CATALINA_OPTS="$CATALINA_OPTS
-Djavax.management.builder.initial=
-Dcom.sun.management.jmxremote=true
-Dcom.sun.management.jmxremote.port=12346
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Djava.rmi.server.hostname=127.0.0.1"
2个tomcat应用程序启动jmx端口后,重启tomcat.
3,下载获取数据的测试工具
cd /etc/zabbix/zb_monitor_script
wget https://coding.net/s/73ce6ac2-a902-45f3-b781-d97d5cbc79d1
简单测试:
java -jar jmxcmd.jar - 127.0.0.1:12345
java -jar jmxcmd.jar - 127.0.0.1:12346
4,定义自动发现脚本
cd /etc/zabbix/zb_monitor_script
vim tomcat_discovery.py
#!/usr/bin/env python
# -*- coding: utf-8 -*-
# @Time : 2018/9/17 下午9:13
# @Author : lin
# @File : discovery tomcat.py import json,subprocess args="sudo /bin/find /usr/local/ -name 'server.xml'|awk -F '/' '{print $4}'|sort|uniq" t=subprocess.Popen(args,shell=True,stdout=subprocess.PIPE).communicate()[0] tomcats=[] for tomcat in t.split('\n'):
if len(tomcat) != 0:
tomcats.append({'{#TOMCAT_NAME}':tomcat}) print json.dumps({'data':tomcats},indent=4,separators=(',',':'))
chmod a+x tomcat_discovery.py
测试,自动发现,看看能不能发现tomcat,如下说明无问题。
python tomcat_discovery.py
5,配置监控tomcat的脚本
vim tomcat_monitor.sh
#!/bin/bash
source /etc/profile
[ $# -ne ] && echo 'The scripts need 2 parameters'&&exit
TOMCAT_NAME=$
ITEM=$ JMX_PORT=`ps -ef|grep $|grep -vE 'grep|sh'|awk -F '=' '{print $6}'|awk '{print $1}'`
#读取server.xml配置文件,获取端口
xml=/usr/local/$/conf/server.xml PORT=`sed -n ''p $xml |awk -F '[= " ]+' '{print $4}' `

6,定义监控配置文件
cd /etc/zabbix/zabbix_agentd.d/
vim userparameter_tomcat.conf
UserParameter=tomcat.discovery,/usr/bin/python /etc/zabbix/zb_monitor_script/tomcat_discovery.py
UserParameter=tomcat.status[*],/bin/bash /etc/zabbix/zb_https://coding.net/s/03996946-8b2c-4b42-9bdf-957f17800315monitor_script/tomcat_monitor.sh $ $
7,重启zabbix-agent服务
/etc/init.d/zabbix-agent restart
8,web界面添加主机,导入模版。
