zabbix通过JMX监控Tomcat

一、zabbix java gateway编译参数如下

如果没有zabbix的jmx封装的话,自己来写自定义脚本监控tomcat也是可以的,只是很麻烦。通过zabbix的jmx,监控tomcat就变得很简单。

java环境安装:

yum install java-1.7.0-openjdk java-1.7.0-openjdk-devel -y

要使用java gateway需要在源码安装zabbix的时候,在./configure的时候加入

--enable-java

以下是我的zabbix server编译参数:

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

看下有没有成功:

ll -h /usr/local/zabbix/sbin/zabbix_java/

二、zabbix server启动java gateway

/usr/local/zabbix/sbin/zabbix_java/startup.sh

三、看下java gateway的监控端口(10052)

ps auxfw|grep JavaGateway

四、zabbix server配置vim /usr/local/zabbix/etc/zabbix_server.conf

JavaGateway=192.168.1.106
JavaGatewayPort=10052
StartJavaPollers=5

zabbix server --> zabbix java gateway --> 访问tomcat服务器

五、tomcat服务器加入如下配置(vim /usr/local/tomcat/bin/catalina.sh)

CATALINA_OPTS="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=12345 -Djava.rmi.server.hostname=192.168.1.106"
重启tomcat:
/usr/local/tomcat/bin/startup.sh 

需要先下载一个cmdline-jmxclient-0.10.3.jar,用来测试jmx获取监控数据,获取没问题后再在zabbix网页上添加监控项目。

六、自定义添加

jmx一般监控,都适用,讲讲自定义监控tomcat:
cd /usr/local/tomcat/
java -jar cmdline-jmxclient-0.10.3.jar - 192.168.1.106:12345 java.lang:type=Memory HeapMemoryUsage
java -jar cmdline-jmxclient-0.10.3.jar - 192.168.1.106:12345 java.lang:type=OperatingSystem ProcessCpuLoad

zabbix上添加监控:

先添加主机,使用jmx的接口进行监控。

jmx["java.lang:type=Memory",HeapMemoryUsage.used]默认(单位B)
jmx["java.lang:type=Memory",HeapMemoryUsage.max]默认(单位B)
jmx["java.lang:type=Memory",NonHeapMemoryUsage.max]  默认(单位B)
jmx["java.lang:type=Memory",NonHeapMemoryUsage.used]  默认(单位B)
jmx["java.lang:type=ClassLoading",UnloadedClassCount]  默认
jmx["java.lang:type=ClassLoading",LoadedClassCount]  默认
jmx["java.lang:type=ClassLoading",TotalLoadedClassCount] 默认
jmx["java.lang:type=OperatingSystem",OpenFileDescriptorCount] 默认
jmx["java.lang:type=OperatingSystem",MaxFileDescriptorCount] 默认
jmx["java.lang:type=OperatingSystem",ProcessCpuLoad]浮点数 % 自定义倍数100
jmx["java.lang:type=Runtime",Uptime] 默认 探测是否存活(nodata3分钟)

tomcat监控:

java -jar cmdline-jmxclient-0.10.3.jar - 192.168.1.106:12345 |grep -i Catalina
java -jar cmdline-jmxclient-0.10.3.jar - 192.168.1.106:12345 "Catalina:name=\"http-bio-8080\",type=GlobalRequestProcessor" requestCount

zabbix上添加如下:

jmx["Catalina:name=\"http-bio-8080\",type=GlobalRequestProcessor",requestCount] 每秒的请求数
jmx["Catalina:name=\"http-bio-8080\",type=ThreadPool",maxThreads]

七、使用模板

jmx generic
jmx tomcat 默认的很多不能用,得改下

tomcat的安装脚本:

#!/bin/sh
LANG=C

if [ -d "/usr/local/tomcat/" ];then
    echo "tomcat is install"
    exit 1
else
    echo "tomcat in not install"
fi

my_gcc=`rpm -qa gcc`
if [[ -n "$my_gcc" ]];then
    echo "$my_gcc" 
else
    yum -y install gcc
fi

my_make=`rpm -qa make`
if [[ -n "$my_make" ]];then
    echo "$my_make"
else
    yum -y install make 
fi

my_tar=`rpm -qa tar`
if [[ -n "$my_tar" ]];then
    echo "$my_tar"
else
    yum -y install tar
fi

my_openssl=`rpm -qa openssl`
if [[ -n "$my_openssl" ]];then
    echo "$my_openssl"
else
    yum -y install openssl
fi

my_openssl_devel=`rpm -qa openssl-devel`
if [[ -n "$my_openssl_devel" ]];then
    echo "$my_openssl_devel"
else
    yum -y install openssl-devel
fi

my_jdk=`rpm -qa java-1.7.0-openjdk`
if [[ -n "$my_jdk" ]];then
    echo "$my_jdk"
else
    yum -y install java-1.7.0-openjdk
fi

cd /usr/local/src
tar -zxvf apache-tomcat-7.0.63.tar.gz
mv apache-tomcat-7.0.63 /usr/local/tomcat
echo "install tomcat success. tomcat is in /usr/local/tomcat"
exit 0
