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(' '): 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 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}'` #读取server.xml配置文件,获取端口 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 function HeapMemoryUsage() { java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=Memory HeapMemoryUsage 2> $ITEM.$JMX_PORT } function EdenSpaceUsage() { java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=MemoryPool,name=Eden Space Usage 2> $ITEM.$JMX_PORT } function SurvivorSpaceUsage() { java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=MemoryPool,name=Survivor Space Usage 2> $ITEM.$JMX_PORT } function TenuredGenUsage() { java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=MemoryPool,name=Tenured Gen Usage 2> $ITEM.$JMX_PORT } function NonHeapMemoryUsage() { java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=Memory NonHeapMemoryUsage 2> $ITEM.$JMX_PORT } function MetaspaceUsage() { java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=MemoryPool,name=Metaspace Usage 2> $ITEM.$JMX_PORT } function CodeCacheUsage() { java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=MemoryPool,name=Code Cache Usage 2> $ITEM.$JMX_PORT } function CompressedClassSpaceUsage() { java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=MemoryPool,name=Compressed Class Space Usage 2> $ITEM.$JMX_PORT } function TotalLoadedClassCount() { java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=ClassLoading TotalLoadedClassCount 2> $ITEM.$JMX_PORT } function LoadedClassCount() { java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=ClassLoading LoadedClassCount 2> $ITEM.$JMX_PORT } function UnloadedClassCount() { java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=ClassLoading UnloadedClassCount 2> $ITEM.$JMX_PORT } function TotalStartedThreadCount() { java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=Threading TotalStartedThreadCount 2> $ITEM.$JMX_PORT } function ThreadCount() { java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=Threading ThreadCount 2> $ITEM.$JMX_PORT } function PeakThreadCount() { java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=Threading PeakThreadCount 2> $ITEM.$JMX_PORT } function maxThreads() { java -jar $cmd - 127.0.0.1:$JMX_PORT Catalina:name="http-nio-$PORT",type=ThreadPool maxThreads 2> $ITEM.$JMX_PORT } function currentThreadCount() { java -jar $cmd - 127.0.0.1:$JMX_PORT Catalina:name="http-nio-$PORT",type=ThreadPool currentThreadCount 2>$ITEM.$JMX_PORT } function currentThreadsBusy() { java -jar $cmd - 127.0.0.1:$JMX_PORT Catalina:name="http-nio-$PORT",type=ThreadPool currentThreadsBusy 2>$ITEM.$JMX_PORT } function GlobalRequestProcessor_bytesReceived() { java -jar $cmd - 127.0.0.1:$JMX_PORT Catalina:name="http-nio-$PORT",type=GlobalRequestProcessor bytesReceived 2>$ITEM.$JMX_PORT } function GlobalRequestProcessor_bytesSent() { java -jar $cmd - 127.0.0.1:$JMX_PORT Catalina:name="http-nio-$PORT",type=GlobalRequestProcessor bytesSent 2>$ITEM.$JMX_PORT } function requestCount() { java -jar $cmd - 127.0.0.1:$JMX_PORT Catalina:name="http-nio-$PORT",type=GlobalRequestProcessor requestCount 2>$ITEM.$JMX_PORT } function errorCount() { java -jar $cmd - 127.0.0.1:$JMX_PORT Catalina:name="http-nio-$PORT",type=GlobalRequestProcessor errorCount 2>$ITEM.$JMX_PORT } function jvmUptime() { java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=Runtime Uptime 2> $ITEM.$JMX_PORT } # function collectdata() # { # java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=Memory HeapMemoryUsage 2> $ITEM.$JMX_PORT # java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=MemoryPool,name=Eden Space Usage 2> $ITEM.$JMX_PORT # java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=MemoryPool,name=Survivor Space Usage 2> $ITEM.$JMX_PORT # java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=MemoryPool,name=Tenured Gen Usage 2> $ITEM.$JMX_PORT # java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=Memory NonHeapMemoryUsage 2> $ITEM.$JMX_PORT # java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=MemoryPool,name=Metaspace Usage 2> $ITEM.$JMX_PORT # java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=MemoryPool,name=Code Cache Usage 2> $ITEM.$JMX_PORT # java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=MemoryPool,name=Compressed Class Space Usage 2> $ITEM.$JMX_PORT # java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=ClassLoading TotalLoadedClassCount 2> $ITEM.$JMX_PORT # java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=ClassLoading LoadedClassCount 2> $ITEM.$JMX_PORT # java -jar $cmd - 127.0.0.1:$JMX_PORT java.lang:type=ClassLoading UnloadedClassCount 2> $ITEM.$JMX_PORT # } case $ITEM in #统计堆空间堆 HeapMemoryUsage.max) HeapMemoryUsage sed -n '4p' $ITEM.$JMX_PORT|awk '{print $2}' ;;

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 $1 $2
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。
