zabbix 自定义监控服务配置

zabbix 自定义监控服务配置

注：本文基于/]# mkdir /zabbix # 个人习惯，可忽略 [root@agent /]# cd /zabbix/ [root@agent /]# rz [root@agent zabbix]# tar zxf zabbix-3.2.1.tar.gz [root@agent zabbix]# cd zabbix-3.2.1/ [root@agent zabbix-3.2.1]# useradd -M -s /sbin/nologin zabbix [root@agent zabbix-3.2.1]# ./configure --prefix=/usr/local/zabbix --enable-agent && make && make install [root@agent zabbix-3.2.1]# cp misc/init.d/fedora/core/zabbix_agentd /etc/init.d/ [root@agent /]# sed -i 's/BASEDIR=\/usr\/local/BASEDIR=\/usr\/local\/zabbix/g' /etc/init.d/zabbix_agentd [root@agent /]# sed -i 's/PIDFILE=\/tmp\/$BINARY_NAME.pid/PIDFILE=$BASEDIR\/logs\/$BINARY_NAME.pid/g' /etc/init.d/zabbix_agentd [root@agent /]# chmod +x /etc/init.d/zabbix_agentd [root@agent /]# sed -i 's/# PidFile=\/tmp\/zabbix_agentd.pid/PidFile=\/usr\/local\/zabbix\/logs\/zabbix_agentd.pid/g' /usr/local/zabbix/etc/zabbix_agentd.conf [root@agent /]# sed -i 's/LogFile=\/tmp\/zabbix_agentd.log/LogFile=\/usr\/local\/zabbix\/logs\/zabbix_agentd.log/g' /usr/local/zabbix/etc/zabbix_agentd.conf [root@agent /]# sed -i 's/Server=127.0.0.1/Server=192.168.171.133/g' /usr/local/zabbix/etc/zabbix_agentd.conf [root@agent /]# sed -i 's/# ListenPort=10050/ListenPort=10050/g' /usr/local/zabbix/etc/zabbix_agentd.conf [root@agent /]# sed -i 's/ServerActive=127.0.0.1/ServerActive=192.168.171.133/g' /usr/local/zabbix/etc/zabbix_agentd.conf [root@agent /]# sed -i 's/Hostname=Zabbix server/Hostname=192.168.171.134/g' /usr/local/zabbix/etc/zabbix_agentd.conf [root@agent /]# sed -i 's/# Timeout=3/Timeout=15/g' /usr/local/zabbix/etc/zabbix_agentd.conf [root@agent /]# sed -i 's/# Include=\/usr\/local\/etc\/zabbix_agentd.conf.d\//Include=\/usr\/local\/zabbix\/etc\/zabbix_agentd.conf.d\//g' /usr/local/zabbix/etc/zabbix_agentd.conf [root@agent /]# sed -i 's/# UnsafeUserParameters=0/UnsafeUserParameters=1/g' /usr/local/zabbix/etc/zabbix_agentd.conf [root@agent /]# egrep -v '^$|^#' /usr/local/zabbix/etc/zabbix_agentd.conf PidFile=/usr/local/zabbix/logs/zabbix_agentd.pid LogFile=/usr/local/zabbix/logs/zabbix_agentd.log Server=192.168.171.133 ListenPort=10050 ServerActive=192.168.171.133 Hostname=192.168.171.134 Timeout=15 Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/ UnsafeUserParameters=1 [root@agent /]# mkdir -p /usr/local/zabbix/logs # 创建日志存放路径 [root@agent /]# chown -R zabbix:zabbix /usr/local/zabbix/ # 赋予权限 [root@agent /]# /etc/init.d/zabbix_agentd start # 启动agent Reloading systemd: [ OK ] Starting zabbix_agentd (via systemctl): [ OK ] [root@agent /]# cat > /tmp/memavailable.sh << EOF > #!/bin/bash > free -m | grep Mem | awk '{print $NF}' > EOF [root@agent /]# chmod +x /tmp/memavailable.sh [root@agent /]# cat > /usr/local/zabbix/etc/zabbix_agentd.conf.d/memtest.conf << EOF > UserParameter=memtest,sh /tmp/memavailable.sh > EOF [root@agent zabbix]# /etc/init.d/zabbix_agentd restart Restarting zabbix_agentd (via systemctl): [ OK ]

#服务端测试： [root@zabbix /]# zabbix_get -s 192.168.171.134 -p 10050 -k "memtest" 1307

#再原有的配置文件基础上再添加几行 [root@agent /]# echo 'UserParameter=nginx.info[*],/usr/local/zabbix/scripts/nginx.sh $1' >> /usr/local/zabbix/etc/zabbix_agentd.conf [root@agent /]# echo "UserParameter=nginx.ping[*],netstat -anput | grep -w 80 | grep -w LISTEN | wc -l" >> /usr/local/zabbix/etc/zabbix_agentd.conf [root@agent /]# egrep -v '^$|^#' /usr/local/zabbix/etc/zabbix_agentd.conf PidFile=/usr/local/zabbix/logs/zabbix_agentd.pid LogFile=/usr/local/zabbix/logs/zabbix_agentd.log Server=192.168.171.133 ListenPort=10050 ServerActive=192.168.171.133 Hostname=192.168.171.134 Timeout=15 Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/ UnsafeUserParameters=1 UserParameter=nginx.info[*],/usr/local/zabbix/scripts/nginx.sh $1 UserParameter=nginx.ping[*],netstat -anput | grep -w 80 | grep -w LISTEN | wc -l

2、在Nginx服务器上编写Nginx脚本

[root@agent /]# mkdir /usr/local/zabbix/scripts [root@agent /]# cd /usr/local/zabbix/scripts/ [root@agent scripts]# vim nginx.sh #!/bin/bash case $1 in index) RS=`curl -s -I 192.168.171.134/index.html |head -n1 |awk '{print $2}'` echo $RS ;; WorkerProcesses) RS=`ps aux |grep nginx | grep -w worker |wc -l` echo $RS ;; bps) RS=`ab -q -n 1000 -c 1000 |grep Request | awk '{print $4}'` echo $RS ;; Current) LINES=`cat /usr/local/nginx/logs/access.log |wc -l` sleep 1 NOW_LINES=`cat /usr/local/nginx/logs/access.log |wc -l` echo $NOW_LINES $LINES | awk '{print $1 -$2}' ;; IP) RS=`cat /usr/local/nginx/logs/access.log | awk '{print $1}' |sort -u | wc -l` echo $RS ;; VirtualHost) RS=`cat /usr/local/nginx/conf/nginx.conf |grep -v '#' | grep server_name | wc -l` echo $RS ;; MD5) RS=`md5sum /usr/local/nginx/conf/nginx.conf |awk '{print $1}'` echo $RS ;; PV) RS=`wc -l /usr/local/nginx/logs/access.log | awk '{print $1}'` echo $RS ;; esac #调整相应权限，需要所有用户都可以执行netstat命令 [root@agent scripts]# chmod +s /usr/bin/netstat [root@agent scripts]# chmod +x nginx.sh [root@agent scripts]# /etc/init.d/zabbix_agentd restart Restarting zabbix_agentd (via systemctl): [ OK ]

3、配置Zabbix-Server Web界面在配置web界面前，可现在Zabbix-Server端测试一下相关信息是否可以获得，以便验证脚本的正确性（同时ab压力测试是必须要有的，Server端和Agent端都要装该命令）

[root@zabbix /]# yum -y install httpd-tools [root@zabbix /]# ab -q -n 1000 -c 1000 | grep Request | awk '{print $4}' 7665.77 #有信息返回则表示正常

[root@zabbix /]# cat a.sh #!/bin/bash while true do ab -n 1000 -c 100 192.168.171.134/index.html &> /dev/null done [root@zabbix /]# sh a.sh

如果需要开启监控Tomcat功能，在编译zabbix server端时，需要添加--enable_java 参数。1、Zabbix Server安装zabbix_java_gateway程序zabbix_java_gateway程序既可以安装在zabbix server端，也可以安装在被监控端，不过一般都是安装在Zabbix server端，这里我就安装在Zabbix Server端。

[root@zabbix /]# cd /zabbix/ [root@zabbix zabbix]# rpm -ivh zabbix-java-gateway-3.2.1-1.el7.x86_64.rpm [root@zabbix zabbix]# cd /etc/zabbix/ [root@zabbix zabbix]# sed -i 's/# LISTEN_IP="0.0.0.0"/LISTEN_IP="0.0.0.0"/g' zabbix_java_gateway.conf [root@zabbix zabbix]# sed -i 's/# LISTEN_PORT=10052/LISTEN_PORT=10052/g' zabbix_java_gateway.conf [root@zabbix zabbix]# egrep -v '^$|^#' zabbix_java_gateway.conf LISTEN_IP="0.0.0.0" LISTEN_PORT=10052 PID_FILE="/var/run/zabbix/zabbix_java.pid" TIMEOUT=3 #启动zabbix-java [root@zabbix zabbix]# systemctl start zabbix-java-gateway.service [root@zabbix zabbix]# netstat -anput | grep 10052 # 确定端口在接听 tcp6 0 0 :::10052 :::* LISTEN 15501/java [root@zabbix zabbix]# cd / [root@zabbix /]# sed -i 's/# JavaGateway=/JavaGateway=192.168.171.133/g' /usr/local/zabbix/etc/zabbix_server.conf [root@zabbix /]# sed -i 's/# JavaGatewayPort=10052/JavaGatewayPort=10052/g' /usr/local/zabbix/etc/zabbix_server.conf [root@zabbix /]# sed -i 's/# StartJavaPollers=0/StartJavaPollers=5/g' /usr/local/zabbix/etc/zabbix_server.conf [root@zabbix /]# /etc/init.d/zabbix_server restart Restarting zabbix_server (via systemctl): [ OK ]

2、测试端配置Tomcat这里我安装在了nginx那台服务器上

[root@agent /]# rpm -qa | grep jdk java-1.8.0-openjdk-headless-1.8.0.242.b08-0.el7_7.x86_64 java-1.8.0-openjdk-devel-1.8.0.242.b08-0.el7_7.x86_64 java-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64 java-1.7.0-openjdk-1.7.0.111-2.6.7.8.el7.x86_64 java-1.7.0-openjdk-headless-1.7.0.111-2.6.7.8.el7.x86_64 copy-jdk-configs-3.3-10.el7_5.noarch [root@agent /]# rpm -e --nodeps java-1.8.0-openjdk-headless-1.8.0.242.b08-0.el7_7.x86_64 [root@agent /]# rpm -e --nodeps java-1.7.0-openjdk-headless-1.7.0.111-2.6.7.8.el7.x86_64 [root@agent /]# mkdir tomcat [root@agent /]# cd tomcat/ [root@agent tomcat]# rz [root@agent tomcat]# ls apache-tomcat-8.5.35.tar.gz jdk-8u211-linux-x64.tar.gz [root@agent tomcat]# tar zxf jdk-8u211-linux-x64.tar.gz -C /usr/local/ [root@agent tomcat]# tar zxf apache-tomcat-8.5.35.tar.gz [root@agent tomcat]# mv apache-tomcat-8.5.35 /usr/local/tomcat [root@agent tomcat]# vim /etc/profile export JAVA_HOME=/usr/local/jdk1.8.0_211 export JRE_HOME=/usr/local/jdk1.8.0_211/jre export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH [root@agent tomcat]# . /etc/profile [root@agent tomcat]# java -version java version "1.8.0_211" Java(TM) SE Runtime Environment (build 1.8.0_211-b12) Java HotSpot(TM) 64-Bit Server VM (build 25.211-b12, mixed mode) #kaiqi开启tomcat的JMX远程管理功能 [root@agent /]# vim /usr/local/tomcat/bin/catalina.sh export JDK_JAVA_OPTIONS # 跳转到306行，添加如下内容 CATALINA_OPTS=" $CATALINA_OPTS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=8888 -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=192.168.171.134 -Dcom.sun.management.jmxremote.authenticate=false" #注：上面的IP为Tomcat本机的IP，端口“8888”可以自定义，不要冲突即可 [root@agent /]# /usr/local/tomcat/bin/startup.sh [root@agent /]# netstat -anput | grep 8888 tcp6 0 0 :::8888 :::* LISTEN 70730/java [root@agent /]# netstat -anput | grep 8080 tcp6 0 0 :::8080 :::* LISTEN 70730/java

3、回到Zabbix-server进行JMX连接测试注：该测试需要系统支持图形化桌面，若没有图形化桌面，此验证过程可以省略。

[root@zabbix ~]# jconsole #执行此命令，此命令是Java-gateway提供的。
