Zabbix监控Tomcat操作

Posted 2022-05-30 一点点积累

Zabbix版本：3.2.4

介绍

zabbix监控tomcat，需要zabbix_server开启java poller，zabbix_java开启javaGateway，端口10052，Tomcat JMX开启12345端口，提供性能数据。

数据获取流程为：java poller<-->javaGateway:10052<-->Tomcat:12345

1.1 配置Tomcat JMX

这里需要注意，必须增加-Djava.rmi.server.hostname选项，并且后面的IP就是tomcat服务器的IP

#配置jmx，在需要监控的tomcat服务器上，编辑catalina.sh，加入如下配置
[root@Tomcat bin]# sed -n 249p /usr/local/tomcat/bin/catalina.sh 
CATALINA_OPTS="-server -Xms256m -Xmx512m -XX:PermSize=64M -XX:MaxPermSize=128m -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=192.168.0.224 -Dcom.sun.management.jmxremote.port=12345"

1.2 重启Tomcat

[root@Tomcat bin]# /usr/local/tomcat/bin/shutdown.sh 
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/jdk
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
[root@Tomcat ~]# netstat -antup | grep java
[root@Tomcat bin]# /usr/local/tomcat/bin/startup.sh 
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/jdk
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
[root@Tomcat zabbix]# netstat -antup | grep java
tcp        0      0 :::54031                    :::*                        LISTEN      1521/java           
tcp        0      0 :::8080                     :::*                        LISTEN      1521/java           
tcp        0      0 :::53881                    :::*                        LISTEN      1521/java           
tcp        0      0 :::12345                    :::*                      LISTEN      1521/java          #新增端口 
tcp        0      0 ::ffff:127.0.0.1:8005       :::*                        LISTEN      1521/java           
tcp        0      0 :::8009                     :::*                        LISTEN      1521/java

1.3 编译zabbix，加入java支持

在zabbix server服务器上，编译安装zabbix-server，需要加上--enable-java，以支持jmx监控，如果之前的zabbix server没加此选项，那么需要重新编译安装，编译参数如下：

./configure --prefix=/usr/local/zabbix --with-mysql --with-net-snmp --with-libcurl --enable-server --enable-agent --enable-proxy --enable-java --with-libxml2

特别提示： 在启用--enable-java编译zabbix之前，zabbix server服务器上需要安装JDK，并需要设置JAVA_HOME,以让系统能够识别到jdk的路径

1.3.1 在zabbix-server端安装JDK

#解压jdk
[root@Zabbix_Server ~]# tar xf jdk-8u60-linux-x64.tar.gz -C /usr/local/
[root@Zabbix_Server ~]# ln -s /usr/local/jdk1.8.0_60/ /usr/local/jdk
#配置java环境变量
[root@Zabbix_Server ~]# sed -i.ori $a export JAVA_HOME=/usr/local/jdk\\nexport PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH\\nexport CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar /etc/profile
[root@Zabbix_Server ~]# tail -3 /etc/profile
export JAVA_HOME=/usr/local/jdk
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar
#让环境变量立刻生效
[root@Zabbix_Server ~]# source /etc/profile
#检查java环境变量情况
[root@Zabbix_Server ~]# which java
/usr/local/jdk/bin/java
[root@Zabbix_Server ~]# java -version
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

1.3.2 重新编译zabbix-server服务器端

#重新编译zabbix-server服务器端之前
[root@Zabbix_Server ~]# ll /usr/local/zabbix/sbin/
total 8604
-rwxr-xr-x 1 root root 1165774 Jan 20 15:16 zabbix_agentd
-rwxr-xr-x 1 root root 3672055 Jan 20 15:16 zabbix_proxy
-rwxr-xr-x 1 root root 3966037 Jan 20 15:16 zabbix_server
#开始重新编译zabbix-server服务器端
[root@Zabbix_Server ~]# 
[root@Zabbix_Server ~]# /etc/init.d/zabbix_server stop
Shutting down zabbix_server:                               [  OK  ]
[root@Zabbix_Server ~]# cd /usr/src/zabbix-3.2.4/
[root@Zabbix_Server zabbix-3.2.4]# ./configure --prefix=/usr/local/zabbix --with-mysql --with-net-snmp --with-libcurl --enable-server --enable-agent --enable-proxy --enable-java --with-libxml2
[root@Zabbix_Server zabbix-3.2.4]# make && make install
#重新编译zabbix-server服务器端之后
[root@Zabbix_Server zabbix-3.2.4]# cd /usr/local/zabbix/sbin/
[root@Zabbix_Server sbin]# ll

[root@Zabbix_Server sbin]# cd zabbix_java/
[root@Zabbix_Server zabbix_java]# ll
total 20
drwxr-xr-x 2 root root 4096 Jan 25 22:22 bin

-rwxr-xr-x 1 root root  545 Jan 25 22:22 shutdown.sh    #停止java gateway服务
-rwxr-xr-x 1 root root 2025 Jan 25 22:22 startup.sh     #启动java gateway服务

提示： java gateway服务的配置脚本settings.sh不需要修改任何配置。

1.3.3 启动java Gateway服务

[root@Zabbix_Server zabbix_java]# /usr/local/zabbix/sbin/zabbix_java/startup.sh 
[root@Zabbix_Server zabbix_java]# netstat -antup | grep 10052
tcp        0      0 :::10052                    :::*                        LISTEN      13126/java

1.4 修改zabbix server 配置

默认的情况下，zabbix server未启用javaPollers，需要修改zabbix_server.conf的如下配置

[root@Zabbix_Server zabbix]# cd /usr/local/zabbix/etc/
#修改以下配置文件的内容
[root@Zabbix_Server etc]# cat -n zabbix_server.conf | sed -n 215p;223p;231p
   215  # JavaGateway=
   223  # JavaGatewayPort=10052
   231  # StartJavaPollers=0
#将上述配置文件内容修改成如下
[root@Zabbix_Server etc]# cat -n zabbix_server.conf | sed -n 215p;223p;231p
   215  JavaGateway=127.0.0.1   #JavaGateway的地址
   223  JavaGatewayPort=10052
   231  StartJavaPollers=5
#查看已经打开的java poller进程
[root@Zabbix_Server ~]# ps -ef | grep "java poller" | grep -v grep
zabbix    13233  13172  0 Jan25 ?        00:00:00 /usr/local/sbin/zabbix_server: java poller #1 [got 0 values in 0.000001 sec, idle 5 sec]
zabbix    13234  13172  0 Jan25 ?        00:00:00 /usr/local/sbin/zabbix_server: java poller #2 [got 0 values in 0.000015 sec, idle 5 sec]
zabbix    13235  13172  0 Jan25 ?        00:00:00 /usr/local/sbin/zabbix_server: java poller #3 [got 0 values in 0.000001 sec, idle 5 sec]
zabbix    13236  13172  0 Jan25 ?        00:00:00 /usr/local/sbin/zabbix_server: java poller #4 [got 0 values in 0.000001 sec, idle 5 sec]
zabbix    13237  13172  0 Jan25 ?        00:00:00 /usr/local/sbin/zabbix_server: java poller #5 [got 0 values in 0.000001 sec, idle 5 sec]

1.5 重启zabbix_server服务

[root@Zabbix_Server ~]# /etc/init.d/zabbix_server start
Starting zabbix_server:                                    [  OK  ]
[root@Zabbix_Server ~]# netstat -antup | grep 10051
tcp        0      0 0.0.0.0:10051               0.0.0.0:*                   LISTEN      13172/zabbix_server 
tcp        0      0 192.168.0.220:10051         192.168.0.221:56752         TIME_WAIT   -                   
tcp        0      0 192.168.0.220:10051         192.168.0.221:56754         TIME_WAIT   -                   
tcp        0      0 192.168.0.220:10051         192.168.0.221:56751         TIME_WAIT   -                   
tcp        0      0 192.168.0.220:10051         192.168.0.220:47162         TIME_WAIT   -
