How to monitor multiple JVM processes in Zabbix

1. Scenario description:

Our environment uses microservices. Each program has a separate process and a separate port number. However, some results from the jps query may have duplicate names, so some scripts are not suitable for this scenario.

2. Requirements:

Zabbix-server needs to be used to monitor the jvm process on each Agent (the monitoring items are specifically displayed in the template)

3. Prepare the environment:

1.jvm.py script (not original, copied directly from Github, the Github address is attached here, you can go directly to the target address to view the relevant instructions)

2. https://github.com/qiueer/zabbix/blob/master/Tomcat/usage.txt (zabbix/Tomcat/{jvm.py|Qiueer-Template JMX Generic.xml} template and script address)

3.jdk-8u201-linux-x64.tar.gz

4.Configure or disable iptables

4. Formal Installation

1. Install JDK on each Agent and configure environment variables (upload to the specified directory first). Each Agent performs the following operations.

~]# tar zxvf jdk-8u201-linux-x64.tar.gz
~]# vim /etc/profile // Add the following content #JAVA environment variable export JAVA_HOME=/usr/local/jdk1.8.0_201
  export JRE_HOME=${JAVA_HOME}/jre
  export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib:$CLASSPATH
  export JAVA_PATH=${JAVA_HOME}/bin:${JRE_HOME}/bin
  export PATH=$PATH:${JAVA_PATH}
~]# source /etc/profile
~]# ln -s /usr/local/jdk1.8.0_201/bin/java /bin/java // If you don't make this link, you won't be able to get some information about jvm

2. Upload cmdline and jvm.py to the specified directory for testing (each Agent needs to do this)

zabbix_agentd.d]# pwd
  /etc/zabbix/zabbix_agentd.d
zabbix_agentd.d]# mkdir script
script]#ll
  -rw-r--r-- 1 wenkai person 20124 Sep 10 18:55 cmdline-jmxclient-0.10.3.jar // Upload to the /etc/zabbix/zabbix_agentd.d/script directory -rw-r-xr-x 1 root root 13941 Sep 10 18:57 jvm.py
script]# python jvm.py --list // If data in JSON format can be found, the script is available script]# python jvm.py -b 'java.lang:type=Memory' -k 'HeapMemoryUsage.committed' -p 30497
1020067840

3. Configure the web interface template, download the Qiueer-Template JMX Generic.xml template to the local computer and import it into Zabbix to form a new template. The template is equipped with automatic discovery rules, various monitoring items and triggers;

4. After the configuration is completed, wait for a while to find the data on the monitored host, as follows...

Note: Some monitoring items in the template are not applicable to our services and can be disabled here.
