"Zabbix"-tomcat monitoring and failure restart service

First, monitoring the Tomcat principle

Zabbix_server Open the Java Poller,zabbix_java Open Javagateway, the port is: 10052,tomcat JMX on 12345 provides performance data.

Data acquisition: Java poller--javagateway:10052-tomcat:12345

Ii. installation of Tomcat

Tomcat installs many tutorials on the web.

Third, configure Tomcat JMX

Need to edit Tomcat under/bin/catalina.sh, add configuration:

[Email protected] bin]# cd/usr/local/tomcat-8.0. -/bin[[email protected] bin]# vim catalina.sh# logging_manager="-djava.util.logging.manager=org.apache.juli.classloaderlogmanager"# -----------------------------------------------------------------------------# Insert the following code Java_home=/usr/local/jdk1.8. 0_77java_bin= $JAVA _home/BinPath=$PATH: $JAVA _binclasspath= $JAVA _home/lib/dt.jar: $JAVA _home/lib/tools.jarexport java_home java_bin PATH classpathcatalina_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- dcom.sun.management.jmxremote.port=12345"

Start Tomcat

[[email protected] bin]# sh startup.sh Using catalina_base:/usr/local/tomcat-8.0. -Using catalina_home:/usr/local/tomcat-8.0. -Using Catalina_tmpdir:/usr/local/tomcat-8.0. -/tempusing jre_home:/usr/local/jdk1.8. 0_77using CLASSPATH:/usr/local/tomcat-8.0. -/bin/bootstrap.jar:/usr/local/tomcat-8.0. -/bin/tomcat-Juli.jartomcat started. [Email protected] bin]# netstat-ntplu | Grep12345TCP0      0:::12345:::* LISTEN52472/java# Startup Success

Zabbix_server Configuration

Java Support

Compile and install Zabbix server needs to add--enable-java to support JMX monitoring

Zabbix Basic Installation: http://www.cnblogs.com/hukey/p/5458622.html

Start Zabbix_java

[Email protected] zabbix_java]# cd/usr/local/zabbix-2.4. 8/sbin/10052tcp        0      0 :::10052                    :::*                        LISTEN      52733/java     # Start success

zabbix_server.conf Configuration

[[email protected] ~]# grep java/usr/local/zabbix-2.4.8/etc/zabbix_server.conf | grep =Javagateway=127.0.0.1Javagatewayport=10052startjavapollers=5
[[Email protected] ~]# service zabbix_server Restart # restart Zabbix_server
Shutting down zabbix_server: [OK]
Starting zabbix_server: [OK]

Iv. Import Templates

Because the Zabbix original template is not compatible with Tomcat and so on. The template needs to be re-imported.

Configuration--Hosts

Click Update Submission

Configuration--Templates---Import

Template: Link: http://pan.baidu.com/s/1b0Hm02 Password: 631h

On--Import template imports complete.

Configuration--Hosts--Templates

Customtomcat is the imported template, which is used here.

Here you can find that JMX also turns green, indicating a successful connection.

Data has been generated and tomcat monitoring is complete.

Five, tomcat failure automatic restart

Modify the agentd.conf configuration file, change the restart to take effect

[[email protected] bin]# grep enableremotecommands/usr/local/zabbix-2.4. 8/etc/zabbix_agentd.conf### option:enableremotecommandsenableremotecommands=1    # Modified to 1
[Email protected] bin]# service Zabbix_agentd restart
Shutting down ZABBIX_AGENTD: [OK]
Starting ZABBIX_AGENTD: [OK]

Configure sudo to give permissions to Zabbix users, or zabbix_agent cannot execute commands.

[email protected] bin]# Visudo root    all =(All)       Allzabbix  all =nopasswd:   Allzabbix  all =nopasswd:   /usr/ local/tomcat-8.0. /bin/- Zabbix    /home/zabbix:no such file or directory    -bash- 4.1$     

Server-side configuration:

Create Item

Add

Create Trigger

Add

The place with the red box is the place to be adjusted.

Update submission.

So far, the Zabbix_server configuration is complete.

Turn off Tomcat for the test restart function.

[email protected] bin]# pwd/usr/local/tomcat-8.0. -/bin[[email protected] bin]# sh shutdown.sh Using catalina_base:/usr/local/tomcat-8.0. -Using catalina_home:/usr/local/tomcat-8.0. -Using Catalina_tmpdir:/usr/local/tomcat-8.0. -/tempusing jre_home:/usr/local/jdk1.8. 0_77using CLASSPATH:/usr/local/tomcat-8.0. -/bin/bootstrap.jar:/usr/local/tomcat-8.0. -/bin/tomcat-juli.jar

[[email protected] bin]# visudo#defaults    Requiretty in Visudo comment out this is the weight of the heavy, remember. Otherwise, viewing the status of Zabbix on the web is sent. But the agent does not actually execute the command.

8080 TCP         0      0 0.0. 0.0:8080                0.0.  0.0:*                   LISTEN      4179/java

Auto start successful.
