背景說明：html

因爲zabbix監控使用自帶的模版，只能監控主機上只有1個tomcat的場景適合，雖然網上不少朋友都是在每一個監控項上面添加一個空格來解決問題。可是我的感受這種方法仍是蠻麻煩的，因此寫一篇使用自動發現tomcat並監控。java

1,在一臺主機上安裝2個tomcat，安裝完1個tomcat，複製1個便可。複製完以後修改tomcat的端口便可。python

http://www.javashuo.com/article/p-eoiugjke-gp.htmlweb

2，進入到apache-tomcat1目錄，開啓jmxport端口。shell

在被監控的apache-tomcat1應用程序的找到catalina.sh,添加以下內容apache

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"

在被監控的apache-tomcat2應用程序的找到catalina.sh,添加以下內容json

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個tomcat應用程序啓動jmx端口後，重啓tomcat.vim

3,下載獲取數據的測試工具緩存

cd /etc/zabbix/zb_monitor_scripttomcat

wget https://coding.net/s/73ce6ac2-a902-45f3-b781-d97d5cbc79d1

簡單測試：

java -jar jmxcmd.jar - 127.0.0.1:12345

java -jar jmxcmd.jar - 127.0.0.1:12346

4,定義自動發現腳本

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

測試，自動發現，看看能不能發現tomcat,以下說明無問題。

python tomcat_discovery.py

5,配置監控tomcat的腳本

vim tomcat_monitor.sh

#!/bin/bash
source /etc/profile
[  $# -ne 2 ] && echo 'The scripts need 2 parameters'&&exit 1 
TOMCAT_NAME=$1
ITEM=$2

JMX_PORT=`ps -ef|grep $1|grep -vE 'grep|sh'|awk -F '=' '{print $6}'|awk '{print $1}'`
#讀取server.xml配置文件，獲取端口
xml=/usr/local/$1/conf/server.xml

PORT=`sed -n '69'p $xml |awk -F '[= " ]+' '{print $4}' `
cmd=/etc/zabbix/zb_monitor_script/cmdline-jmxclient-0.10.3.jar
logdir=/tmp/zabbix_tmp
[ ! -d "$logdir" ] && mkdir -p $logdir && chmod 777 $logdir
cd $logdir

6,定義監控配置文件

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  $1 $2

7,重啓zabbix-agent服務

/etc/init.d/zabbix-agent restart

8,web界面添加主機，導入模版。
