单一实例手动部署：
注释：参考的一位博主的博客后续做的修改，那个博主的网址找不到了！！！！
背景：
1、每台测试机上已经有十几个tomcat实例，需要添加tomcat的监控端口,监控端口12345后记累加计算；
2、后续会加新服务器开新的tomcat实例，规划tomcat的监控端口为：30000~300300；
主要应对多实例（第一种情况）
约定：
zbbix配置文件：/etc/zabbix/
脚本文件：/etc/zabbix/scripts/
其他文件：/tmp/
1、下载catalina-jmx-remote.jar
放置到/tmp/目录下：（需墙）
下载地址：http://archive.apache.org/dist/tomcat/tomcat-8/v8.5.30/bin/extras/catalina-jmx-remote.jar
2、第一个脚本
cd /etc/zabbix/scripts
vim add_service_tomcat.sh
#!/bin/bash #修改为对应的tomcat的目录 t_datadir=`find /usr/local/webserver/*/bin/ -name catalina.sh|awk -F "/bin/catalina.sh" '{print $1}'` tomcat_no=`find /usr/local/webserver/*/bin/ -name catalina.sh|awk -F "/bin/catalina.sh" '{print $1}'|wc -l` #监控的端口启始端口n_port=12345 #修改为对应的接入网卡local_ip=`ifconfig eth2 |awk -F '[ :]+' 'NR==2 {print $3}'` for tomcat in $t_datadirdo m_no=`cat -n $tomcat/bin/catalina.sh|grep 'Execute The Requested Command'|awk '{print $1}'` #在该行的下边插入如下几行 cp $tomcat/bin/catalina.sh $tomcat/bin/catalina.sh_bak #先备份原文件 #把catalina-jmx-remote.jar放置/tmp目录下，方便拷贝 cp /tmp/catalina-jmx-remote.jar $tomcat/lib/catalina-jmx-remote.jar #注意这个地方，需要把软件包拷贝到对应的目录下 sed -i ''$m_no'a CATALINA_OPTS="-Dcom.sun.management.jmxremote=true' $tomcat/bin/catalina.sh #插入配置 let "m_no=m_no+1" #切换到新的行 sed -i ''$m_no'a -Djava.rmi.server.hostname='$local_ip'' $tomcat/bin/catalina.sh let "m_no=m_no+1" sed -i ''$m_no'a -Dcom.sun.management.jmxremote.port='$n_port'' $tomcat/bin/catalina.sh let "m_no=m_no+1" sed -i ''$m_no'a -Dcom.sun.management.jmxremote.ssl=false' $tomcat/bin/catalina.sh let "m_no=m_no+1" sed -i ''$m_no'a -Dcom.sun.management.jmxremote.authenticate=false"' $tomcat/bin/catalina.sh let "n_port=n_port+1" done #以下为测试环境添加的配置，忽略！ ##server.mxl##M_mxlfind=`find /application/tomcat*/conf/server.xml -name server.xml | awk -F "/conf/server.xml" '{print $1}'`##Smxl_no=`find /application/tomcat*/conf/server.xml -name server.xml | awk -F "/conf/server.xml" '{print $1}'|wc -l`#for Mxl in $t_datadir#do# S_hc=`cat -n $Mxl/conf/server.xml|grep 'ThreadLocalLeakPreventionListener'|awk '{print $1}'`## let "Smxl_no=Smxl_no+1" # cp $Mxl/conf/server.xml $Mxl/conf/server.xml_bak# sed -i ''$S_hc'a \\ 注释：脚本的主要目的是，逐一修改每个Tomcat实例的/bin/catalina.sh文件;只需执行一次即可；分别添加如下内容
export CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote"export CATALINA_OPTS="$CATALINA_OPTS -Djava.rmi.server.hostname=122.114.200.185"export CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote.ssl=false"export CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote.authenticate=false"
3、第二个脚本
[root@agent scripts]#pwd/etc/zabbix/scripts[root@localhost scripts]# vim jmx_discovery.sh #!/bin/basht_datadir=`find /usr/local/webserver/*/bin/ -name catalina.sh|awk -F "/bin/catalina.sh" '{print $1}'`tomcat_no=`find /usr/local/webserver/*/bin/ -name catalina.sh|awk -F "/bin/catalina.sh" '{print $1}'|wc -l`local_ip1=`ifconfig eth2 |awk -F '[ :]+' 'NR==2 {print $3}'`n_port=12345i=1printf '{"data":[\n'for tomcat in $t_datadirdo t_service=`echo "$tomcat"|awk -F"/" '{print $(NF)}'` if [ "$i" != ${tomcat_no} ];then printf "\t\t{ \n" printf "\t\t\t\"{#LOCAL_IP1}\":\"${local_ip1}\",\n" printf "\t\t\t\"{#JMX_PORT}\":\"${n_port}\",\n" printf "\t\t\t\"{#JAVA_NAME}\":\"${t_service}\"},\n" else printf "\t\t{ \n" printf "\t\t\t\"{#LOCAL_IP1}\":\"${local_ip1}\",\n" printf "\t\t\t\"{#JMX_PORT}\":\"${n_port}\",\n" printf "\t\t\t\"{#JAVA_NAME}\":\"${t_service}\"}]}\n" fi let "n_port=n_port+1" let "i=i+1"done 注释：输出json格式的数据。
效果如下：
4、zabbix_agentd.conf 添加如下内容：
#Tomcat UnsafeUserParameters=1UserParameter=java.jmx.discovery,/etc/zabbix/scripts/jmx_discovery.sh#UserParameter=java.Runtime.status[*],/usr/local/jdk1.8/bin/java -jar /lib/cmdline-jmxclient-0.10.3.jar - $1:\$2 java.lang:type=Runtime \$3 2>&1 |grep \$3 |awk '{print $NF}'UserParameter=java.Memory.status[*],/usr/local/jdk1.8/bin/java -jar /lib/cmdline-jmxclient-0.10.3.jar - $1:\$2 java.lang:type=Memory \$3 2>&1 |grep \$3 |awk '{print $NF}'UserParameter=java.System.status[*],/usr/local/jdk1.8/bin/java -jar /lib/cmdline-jmxclient-0.10.3.jar - $1:\$2 java.lang:type=OperatingSystem \$3 2>&1 |grep \$3 |awk '{print $NF}'UserParameter=java.HeapMemoryUsage.status[*],/usr/local/jdk1.8/bin/java -jar /lib/cmdline-jmxclient-0.10.3.jar - $1:\$2 java.lang:type=Memory HeapMemoryUsage 2>&1 |grep \$3 |awk '{print $NF}'UserParameter=java.NonHeapMemoryUsage.status[*],/usr/local/jdk1.8/bin/java -jar /lib/cmdline-jmxclient-0.10.3.jar - $1:\$2 java.lang:type=Memory NonHeapMemoryUsage 2>&1 |grep \$3 |awk '{print $NF}'UserParameter=java.LoadClass.status[*],/usr/local/jdk1.8/bin/java -jar /lib/cmdline-jmxclient-0.10.3.jar - $1:\$2 java.lang:type=ClassLoading \$3 2>&1 |awk '{print $NF}'UserParameter=java.Threading.status[*],/usr/local/jdk1.8/bin/java -jar /lib/cmdline-jmxclient-0.10.3.jar - $1:\$2 java.lang:type=Threading \$3 2>&1 |awk '{print $NF}' 如有其他监控的项，可以按此方式添加即可，注意模板也要更改哦！
注释：
第一行是开启接受自定义的变量；
第二行是给zabbix-server模板使用的变量宏，在模板中定义key的变量。
其他行是key和key值
5、其他操作
#权限设置 chmod +s /usr/bin/findchmod 550 /etc/zabbix/scripts/jmx_discovery.sh chown zabbix.zabbix /etc/zabbix/scripts/ #重启agent服务systemctl restart zabbix-agent.service systemctl enable zabbix-agent.service
6、server端测试agent端设置是否成功
zabbix_get -s 122.114.100.15 -p 10050 -k java.jmx.discovery zabbix_get -s 122.114.100.15 -p 10050 -k "java.HeapMemoryUsage.status[122.114.100.15,12345,used]" #必须要有返回值
6.1、agent自己测试自己
[root@localhost ~]# java -jar /lib/cmdline-jmxclient-0.10.3.jar - 120.120.19.14:12345 java.lang:type=Runtime Uptime 2>&1 |grep Uptime |awk '{print $NF}'183465827 java -jar /lib/cmdline-jmxclient-0.10.3.jar - 120.120.19.14:12345 java.lang:type=Memory HeapMemoryUsage
注释：必须要有返回值
7、实例测试
#重启单个Tomcat实力/application/tomcat/bin/startup.sh/application/tomcat/bin/shutdown.sh
8、模板3.0以上的

注释：导入到zabbix3.0以上的server中，套到相关主机撒上即可
9、其他故障问题
10、一个成功的栗子！
有规划的添加tomcat（第二种情况）
1、还是在#vim /application/tomcat8_1/bin/catalina.sh的
# ----- Execute The Requested Command -----------------------------------------CATALINA_OPTS="-Dcom.sun.management.jmxremote=true-Djava.rmi.server.hostname=10.220.129.140-Dcom.sun.management.jmxremote.port=300000-Dcom.sun.management.jmxremote.ssl=false-Dcom.sun.management.jmxremote.authenticate=false"
2、/etc/zabbix/scripts/prot.sh内容如下
#!/bin/bashServer_Ip=`ifconfig eth0 |awk -F '[ :]+' 'NR==2 {print $3}'`declare -a port_scan=()declare -i j=0scan(){ nc -vz -w 1 127.0.0.1 $1 2> /dev/null if [ $? -eq 0 ];then return 0 else return 1 fi}for i in `seq 30000 30010`do scan $i if [ $? -eq 0 ];then# echo "j=$j" port_scan[$j]=$i j=$((j+1))# echo "$i success." fidonelength=${#port_scan[@]}#printf "{\n"printf '{"data":[\n'for ((i=0;i<$length;i++))do if [ $i -lt $[$length-1] ];then printf "\t\t{ \n" printf "\t\t\t\"{#SERVER_IP}\":\"${Server_Ip}\",\n" printf "\t\t\t\"{#JMX_PORT}\":\"${port_scan[$i]}\"},\n" else printf "\t\t{ \n" printf "\t\t\t\"{#SERVER_IP}\":\"${Server_Ip}\",\n" printf "\t\t\t\"{#JMX_PORT}\":\"${port_scan[$i]}\"}]}\n"# if [ $i -lt $[$length-1] ];then# printf ',' fidone#printf "\n\t]\n"#printf "}\n"
3、#vim /etc/zabbix/zabbix_agentd.conf
#TomcatUserParameter=java.jmx.discovery,/etc/zabbix/scripts/prot.shUserParameter=java.Runtime.status[*],/application/jdk/bin/java -jar /lib/cmdline-jmxclient-0.10.3.jar - $1:\$2 java.lang:type=Runtime \$3 2>&1 |grep \$3 |awk '{print $NF}'UserParameter=java.Memory.status[*],/application/jdk/bin/java -jar /lib/cmdline-jmxclient-0.10.3.jar - $1:\$2 java.lang:type=Memory \$3 2>&1 |grep \$3 |awk '{print $NF}'UserParameter=java.System.status[*],/application/jdk/bin/java -jar /lib/cmdline-jmxclient-0.10.3.jar - $1:\$2 java.lang:type=OperatingSystem \$3 2>&1 |grep \$3 |awk '{print $NF}'UserParameter=java.HeapMemoryUsage.status[*],/application/jdk/bin/java -jar /lib/cmdline-jmxclient-0.10.3.jar - $1:\$2 java.lang:type=Memory HeapMemoryUsage 2>&1 |grep \$3 |awk '{print $NF}'UserParameter=java.NonHeapMemoryUsage.status[*],/application/jdk/bin/java -jar /lib/cmdline-jmxclient-0.10.3.jar - $1:\$2 java.lang:type=Memory NonHeapMemoryUsage 2>&1 |grep \$3 |awk '{print $NF}'UserParameter=java.LoadClass.status[*],/application/jdk/bin/java -jar /lib/cmdline-jmxclient-0.10.3.jar - $1:\$2 java.lang:type=ClassLoading \$3 2>&1 |awk '{print $NF}'UserParameter=java.Threading.status[*],/application/jdk/bin/java -jar /lib/cmdline-jmxclient-0.10.3.jar - $1:\$2 java.lang:type=Threading \$3 2>&1 |awk '{print $NF}'
4、测试结果：
[root@zabbix-server ~]#zabbix_get -s 122.114.200.185 -p 10050 -k java.jmx.discovery{ "data":[ { "{#SERVER_IP}":"122.114.200.185", "{#JMX_PORT}":"30001"}, { "{#SERVER_IP}":"122.114.200.185", "{#JMX_PORT}":"30002"}]}[root@zabbix-server ~]#zabbix_get -s 122.114.200.185 -p 10050 -k "java.HeapMemoryUsage.status[122.114.200.185,30001,used]" 15899208[root@zabbix-server ~]#
5、zabbix模板（各位根据上班的模板修改下对应的宏）
