Zabbix实现对Tomcat的监控
Zabbix实现对Tomcat的监控
环境准备
三台机器：
zabbix_agent 5.0（已安装） Zabbix_java_gateway 5.0 10.0.0.7
zabbix_server 5.0（已安装） 10.0.0.17
Tomcat-8.5（已安装） 10.0.0.27
1. Tomcat开启JMX监控
[root@tomcat ~]#vim /usr/local/tomcat/bin/catalina.sh # USE_NOHUP (Optional) If set to the string true the start command will # use nohup so that the Tomcat process will ignore any hangup # signals. Default is "false" unless running on HP-UX in which # case the default is "true" # ----------------------------------------------------------------------------- #以下为添加内容，添加时注释要去掉 CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote #启动远程监控JMX -Dcom.sun.management.jmxremote.port=12345 #默认启动的JMX端口号，要和zabbix添加主机时候的端口一致即可 -Dcom.sun.management.jmxremote.authenticate=false #不使用用户名密码 -Dcom.sun.management.jmxremote.ssl=false #不使用ssl认证 -Djava.rmi.server.hostname=10.0.0.27" #tomcat主机自己的IP地址，不要写zabbix服务器的地址 #最终添加内容如下（分行写有时候服务会起不来）： CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=12345 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=10.0.0.27" [root@tomcat ~]#systemctl restart tomcat.service #出现8080端口和12345端口，说明服务已正常启动 [root@tomcat ~]#ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 *:22 *:* LISTEN 0 100 127.0.0.1:25 *:* LISTEN 0 100 [::]:8080 [::]:* LISTEN 0 128 [::]:22 [::]:* LISTEN 0 50 [::]:12345 [::]:* LISTEN 0 100 [::1]:25 [::]:* LISTEN 0 50 [::]:34689 [::]:* LISTEN 0 50 [::]:37610 [::]:*- 1

2. 二进制安装Zabbix Java gateway
环境准备
#关闭selinux [root@zabbix_java_gateway ~]#sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config #关闭防火墙 [root@zabbix_java_gateway ~]#systemctl disable --now firewalld #重启生效 [root@zabbix_java_gateway ~]#reboot- 1

2.1 安装zabbix rpm源
[root@zabbix_java_gateway ~]#rpm -Uvh https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm [root@zabbix_java_gateway ~]#sed -i 's#http://repo.zabbix.com#https://mirrors.aliyun.com/zabbix#' /etc/yum.repos.d/zabbix.repo [root@zabbix_java_gateway ~]#yum clean all- 1

2.2 安装Zabbix Java gateway
[root@zabbix_java_gateway ~]#yum list all |grep zabbix-java-gateway zabbix-java-gateway.x86_64 5.0.25-1.el7 zabbix [root@zabbix_java_gateway ~]#yum -y install zabbix-java-gateway.x86_64- 1

2.3 修改Zabbix Java gateway配置文件
[root@zabbix_java_gateway ~]#vim /etc/zabbix/zabbix_java_gateway.conf LISTEN_IP="0.0.0.0" #监听地址 LISTEN_PORT=10052 #Java gateway默认监听10052端口 PID_FILE="/var/run/zabbix/zabbix_java.pid" #PID_FILE文件 START_POLLERS=5 #开启的工作线程数 TIMEOUT=30 #超时时间 [root@zabbix_java_gateway ~]#grep "^[a-Z]" /etc/zabbix/zabbix_java_gateway.conf LISTEN_IP="0.0.0.0" LISTEN_PORT=10052 PID_FILE="/var/run/zabbix/zabbix_java.pid" START_POLLERS=5 TIMEOUT=30- 1

2.4 启动Zabbix Java gateway服务
[root@zabbix_java_gateway ~]#systemctl enable --now zabbix-java-gateway.service [root@zabbix_java_gateway ~]#systemctl status zabbix-java-gateway.service ● zabbix-java-gateway.service - Zabbix Java Gateway Loaded: loaded (/usr/lib/systemd/system/zabbix-java-gateway.service; enabled; vendor preset: disabled) Active: active (running) since Tue 2022-06-28 11:47:32 CST; 6min ago Process: 2486 ExecStart=/usr/sbin/zabbix_java_gateway (code=exited, status=0/SUCCESS) Main PID: 2489 (java) CGroup: /system.slice/zabbix-java-gateway.service └─2489 java -server -Dlogback.configurationFile=/etc/zabbix/zabbix_java_gateway_logback.xml -classpath l...

3. 配置zabbix server调用java gateway
[root@zabbix_server ~]#vim /etc/zabbix/zabbix_server.conf JavaGateway=10.0.0.7 #JavaGateway的所在服务器IP地址 JavaGatewayPort=10052 #JavaGateway的服务端口 StartJavaPollers=5 #从javaGateway采集数据的进程数 #建议让StartJavaPollers选项的值小于或等于START_POLLERS [root@zabbix_server ~]#grep "^[a-Z]" /etc/zabbix/zabbix_server.conf ListenPort=10051 LogType=file LogFile=/var/log/zabbix/zabbix_server.log LogFileSize=500 DebugLevel=3 PidFile=/var/run/zabbix/zabbix_server.pid SocketDir=/var/run/zabbix DBHost=10.0.0.17 DBName=zabbix DBUser=zabbix DBPassword=zabbix DBPort=3306 StartPollers=2 StartPreprocessors=3 StartPollersUnreachable=2 StartTrappers=5 StartPingers=5 StartHTTPPollers=3 StartTimers=3 StartEscalators=1 StartAlerters=3 JavaGateway=10.0.0.7 JavaGatewayPort=10052 StartJavaPollers=5 SNMPTrapperFile=/var/log/snmptrap/snmptrap.log StartSNMPTrapper=1 HousekeepingFrequency=4 MaxHousekeeperDelete=1000000 CacheSize=128M CacheUpdateFrequency=60 StartDBSyncers=6 HistoryCacheSize=128M HistoryIndexCacheSize=32M TrendCacheSize=16M ValueCacheSize=16M Timeout=30 UnavailableDelay=60 AlertScriptsPath=/usr/lib/zabbix/alertscripts ExternalScripts=/usr/lib/zabbix/externalscripts FpingLocation=/usr/sbin/fping LogSlowQueries=3000 TmpDir=/var/run/zabbix/ StartProxyPollers=3 ProxyConfigFrequency=60 ProxyDataFrequency=60 AllowRoot=1 User=root [root@zabbix_server ~]#systemctl restart zabbix-server.service [root@zabbix_server ~]#ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 *:22 *:* LISTEN 0 100 127.0.0.1:25 *:* LISTEN 0 128 *:10050 *:* LISTEN 0 128 *:10051 *:* LISTEN 0 128 127.0.0.1:9000 *:* LISTEN 0 80 [::]:3306 [::]:* LISTEN 0 128 [::]:80 [::]:* LISTEN 0 128 [::]:22 [::]:* LISTEN 0 100 [::1]:25 [::]:* LISTEN 0 128 [::]:10050 [::]:* LISTEN 0 128 [::]:10051 [::]:*- 1

4. zabbix server添加JMX监控
点击【配置-主机-10.0.0.7-web1-添加JMX接口】
5. zabbix server关联模板
6. 验证当前JMX状态及数据
#【JMX绿色】表示JMX主机可用，监控指标检查已成功
