zabbix JMX监控Tomcat及错误解决方法

1.修改zabbix_java相关选项

[[email protected] zabbix]# cd  /usr/local/sbin/zabbix_java
[[email protected] zabbix_java]# vim settings.sh
[[email protected] zabbix_java]# sed -e '/^#/d;/^$/d' settings.sh   #该文件默认全部注释，启用下面几项即可
LISTEN_IP="0.0.0.0"
LISTEN_PORT=10052
PID_FILE="/tmp/zabbix_java.pid"
START_POLLERS=5

2.修改zabbix_server文件

[[email protected] zabbix_java]# sed -e '/^#/d;/^$/d' /usr/local/etc/zabbix_server.conf
LogFile=/tmp/zabbix_server.log
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
[[email protected] zabbix_java]# vim  /usr/local/etc/zabbix_server.conf
[[email protected] zabbix_java]# sed -e '/^#/d;/^$/d' /usr/local/etc/zabbix_server.conf
LogFile=/tmp/zabbix_server.log
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
JavaGateway=127.0.0.1
JavaGatewayPort=10052
StartJavaPollers=5

3.执行startup.sh

[[email protected] zabbix_java]# sh startup.sh &
[[email protected] ~]# netstat -tnlup | grep 10052
tcp        0      0 :::10052                    :::*                        LISTEN      29326/java

4.tomcat端，安装catalina-jmx-remote.jar

[[email protected] ~]# wget  http://archive.apache.org/dist/tomcat/tomcat-7/v7.0.8/bin/extras/catalina-jmx-remote.jar
[[email protected] ~]# mv catalina-jmx-remote.jar /usr/share/java/tomcat6 #yum路径
mv catalina-jmx-remote.jar /usr/local/tomcat/lib/   #源码路径

5.修改catalina.sh文件

[[email protected] tomcat6]# vim /usr/share/tomcat6/bin/catalina.sh
[[email protected] tomcat6]# cat  /usr/share/tomcat6/bin/catalina.sh
CATALINA_OPTS="$CATALINA_OPTS
-Dcom.sun.management.jmxremote
-Djava.rmi.server.hostname=192.168.16.253
-Dcom.sun.management.jmxremote.port=12345
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false"
#tomcat端的IP和指定JMX端口，在/bin/sh下面添加此段

7.重启服务

[[email protected] tomcat6]# /etc/init.d/tomcat6 restart
[[email protected] tomcat6]# /etc/init.d/zabbix-agent restart

8.服务端测试（jar包在附件）

[[email protected] ~]# java -jar /root/cmdline-jmxclient-0.10.3.jar - 192.168.16.251:12345 java.lang:type=Memory NonHeapMemoryUsage

错误一：

[[email protected] ~]# java -jar /root/cmdline-jmxclient-0.10.3.jar - 192.168.16.251:18090 java.lang:type=Memory NonHeapMemoryUsageException in thread "main" java.io.IOException: Failed to retrieve RMIServer stub: javax.naming.ServiceUnavailableException [Root exception is java.rmi.ConnectException: Connection refused to host: 192.168.16.251; nested exception is:     java.net.ConnectException: Connection refused]    at javax.management.remote.rmi.RMIConnector.connect(RMIConnector.java:369)    at javax.management.remote.JMXConnectorFactory.connect(JMXConnectorFactory.java:270)    at org.archive.jmx.Client.execute(Client.java:225)    at org.archive.jmx.Client.main(Client.java:154)Caused by: javax.naming.ServiceUnavailableException [Root exception is java.rmi.ConnectException: Connection refused to host: 192.168.16.251; nested exception is:     java.net.ConnectException: Connection refused]    at com.sun.jndi.rmi.registry.RegistryContext.lookup(RegistryContext.java:122)    at com.sun.jndi.toolkit.url.GenericURLContext.lookup(GenericURLContext.java:205)    at javax.naming.InitialContext.lookup(InitialContext.java:417)    at javax.management.remote.rmi.RMIConnector.findRMIServerJNDI(RMIConnector.java:1955)    at javax.management.remote.rmi.RMIConnector.findRMIServer(RMIConnector.java:1922)    at javax.management.remote.rmi.RMIConnector.connect(RMIConnector.java:287)    ... 3 more

解决：

 cat  /usr/share/tomcat6/bin/catalina.sh
CATALINA_OPTS="$CATALINA_OPTS
-Dcom.sun.management.jmxremote
-Djava.rmi.server.hostname=192.168.16.253
-Dcom.sun.management.jmxremote.port=12345
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false"

错误二：

解决：

sh startup.sh  &   #放入后台启动
