zabbix监控自动发现监控tomcat(V1)

时间：2022-03-06 16:22:20

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}' `

cmd=/etc/zabbix/zb_monitor_script/cmdline-jmxclient-0.10..jar

logdir=/tmp/zabbix_tmp

[ ! -d "$logdir" ] && mkdir -p $logdir && chmod  $logdir

cd $logdir

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。
