zabbix日常监控项java(四)

yum install net-tools      netstat命令
yum -y install bash-completion 命令自动补全包

https://github.com/qiueer/zabbix

  

基本监控流程:被监控端开启snmp或安装agent-----》zabbix端添加主机监控------》添加模板----》添加触发器

 

 

一、使用JMX(使用Zabbix Java Gateway代理)监控java应用

1、zabbix-server端安装:

#安装服务包
yum install -y http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-java-gateway-3.4.1-1.el7.x86_64.rpm
yum -y install java-1.8.0

#配置文件
vim /etc/zabbix/zabbix_java_gateway.conf      #配置文件,默认不需要修改

#启动服务
systemctl start zabbix-java-gateway.service

#查看状态
[root@zabbix ~]# netstat -luntp|grep java
tcp6       0      0 :::10052                :::*                    LISTEN      2352/java


#配置zabbix-server文件
vim /etc/zabbix/zabbix_server.conf   
JavaGateway=10.0.0.200   #JavaGateay地址(zabbix-server地址)
JavaGatewayPort=10052    #监控端口
StartJavaPollers=5       #监控JavaGateway的轮询进程

#重启zabbix-service
systemctl restart zabbix-server.service

 

  

 2、因是实验环境,故简单安装java应用,便于监控测试(实验使用)

详细安装过程请移步:http://blog.oldboyedu.com/java-tomcat/ 

约定:

  软件放置目录:/usr/local/src
      安装路径:/etc/应用名

 

 

  2.1、下载jdk(这里选择jdk8)

下载地址:http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

  2.2、安装jdk

[root@tomcat src]# pwd
/usr/local/src
[root@tomcat src]# tar xf jdk-8u171-linux-x64.tar.gz /etc/
[root@tomcat src]# ln -s /etc/jdk1.8.0_171/ /jdk

sed -i.ori '$a export JAVA_HOME=/etc/jdk\nexport PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH\nexport CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar' /etc/profile

source /etc/profile

[root@tomcat src]# java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)
[root@tomcat src]#

 

 

  2.3、安装tomcat

  下载地址:https://tomcat.apache.org/download-80.cgi

  

 

 

#安装tomcat应用
cd /usr/local/src/  wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-8/v8.5.28/bin/apache-tomcat-8.5.28.tar.gz
tar xf apache-tomcat-8.5.28.tar.gz
mv apache-tomcat-8.5.28 /usr/local/
ln -s /usr/local/apache-tomcat-8.5.28/ /usr/local/tomcat

#启动服务
[root@localhost src]# /usr/local/tomcat/bin/startup.sh 

#查看服务状态
[root@localhost src]# netstat -luntp|grep 8080
tcp6 0 0 :::8080 :::* LISTEN 10420/java

 


#下载安装 catalina-jmx-remote.jar 这个文件放置到Tomcat/lib目录下
[root@tomcat lib]# ll /etc/tomcat/lib/catalina-jmx-remote.jar 
-rw-r--r-- 1 root root 13607 Jun  5  2018 /etc/tomcat/lib/catalina-jmx-remote.jar

 

#修改server.xml配置文件
[root@tomcat lib]# vim  /etc/tomcat/conf/server.xml
 22 <Server port="8005" shutdown="SHUTDOWN">
 23   <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
 24   <!-- Security listener. Documentation at /docs/config/listeners.html
 25   <Listener className="org.apache.catalina.security.SecurityListener" />
 26   -->
 27   <!--APR library loader. Documentation at /docs/apr.html -->
 28   <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
 29   <!-- Prevent memory leaks due to use of particular java/javax APIs-->
 30   <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
 31   <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
 32   <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />
 33   <Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener"   
 34             rmiRegistryPortPlatform="12345" rmiServerPortPlatform="12346" />
注释:33和34行内容是新添加的内容,其他均不用修改

#开启JMX远程监控
vim /etc/tomcat/bin/catalina.sh
添加到Execute The Requested Command 位置下,在最后添加不生效!!!!!!!!!
 
CATALINA_OPTS="$CATALINA_OPTS
-Djava.rmi.server.hostname=122.114.10.146
-Dcom.sun.management.jmxremote=true
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false"

#重启进程
/etc/tomcat/bin/shutdown.sh
/etc/tomcat/bin/startup.sh

#查看端口
[root@tomcat ~]# netstat -luntp              
tcp6       0      0 :::8080              :::*                LISTEN   26311/java                    
tcp6       0      0 :::12345             :::*                LISTEN      26311/java                  
tcp6       0      0 :::12346             :::*                LISTEN      26311/java          
tcp6       0      0 :::45628             :::*                LISTEN      26311/java          
tcp6       0      0 :::10050             :::*                LISTEN      24935/zabbix_agentd 
tcp6       0      0 127.0.0.1:8005       :::*                LISTEN      26311/java          
tcp6       0      0 :::8009              :::*                LISTEN      26311/java  

 

   3、修改防火墙

firewall-cmd --zone=public --add-port=12345/tcp --permanent
firewall-cmd --zone=public --add-port=12346/tcp --permanent
firewall-cmd --reload

 

 

下载测试:

测试法1:

1)下载cmdline-jmxclient-0.10.3.jar文件,下载地址http://crawler.archive.org/cmdline-jmxclient/downloads.html2)本地执行如下命令查看tomcat的堆内存信息
java -jar cmdline-jmxclient-0.10.3.jar - 122.114.10.146:12345 java.lang:type=Memory HeapMemoryUsage
06/05/2018 11:27:46 +0800 org.archive.jmx.Client HeapMemoryUsage: 
committed: 30724096
init: 16777216
max: 253427712
used: 20617872

 

测试方法2:

  

 3、zabbix-server服务web端配置

配置--》主机---添加主机

 

 

注:显示添加完成后,注意看出图情况,我的显示正常出图,再次就不截图了!!!!

自此监控就添加完成,但监控java或tomcat的模板大部分是没有用的,需要我们自己修改,请查 zabbix日常监控项java(四又分之一)
