Install the Zabbix Agent on the ElasticSearch Server
• IP – 192.168.100.10
• Operational System – Ubuntu 20.04
• Hostname – ELASTICSEARCH
Install the required packages on the computer running the ElasticSearch service.
Download and install the GOLANG package.
The GOLANG software was installed on the following directory: /usr/local
In order to work properly, the GO software expects the system to have a set of environment variables.
Let’s create a file to automate the required environment variables configuration.
Here is the file content.
Reboot your computer.
Verify if the required environment variables were created automatically.
Here is the correct output:
Download the Zabbix installation package.
Extract the Zabbix installation package, compile and install the Zabbix agent.
Find the configuration file named: zabbix_agentd.conf.
Edit the file named zabbix_agentd.conf.
Here is the original file, before our configuration.
Here is the new file with our configuration.
The agent was configured to allow the connection from a Zabbix server using the IP address 192.168.100.9.
The Localhost was allowed to request and receive information from the local agent.
Start the Zabbix Agent.
You have finished the Zabbix agent installation.
Now, you can use the Zabbix dashboard to monitor the ElasticSearch service installed on this computer.
Zabbix – Monitor the ElastisSearch service
Access the Zabbix server dashboard and add the Linux computer running the ElasticSearch service as a Host.
Open your browser and enter the IP address of your web server plus /zabbix.
In our example, the following URL was entered in the Browser:
• http://192.168.100.9/zabbix
On the login screen, use the default username and default password.
• Default Username: Admin
• Default Password: zabbix
After a successful login, you will be sent to the Zabbix Dashboard.
On the dashboard screen, access the Configuration menu and select the Host option.
On the top right of the screen, click on the Create host button.
Enter the following information:
• Host Name – Enter a Hostname to identify the ElasticSearch server.
• Visible Hostname – Repeat the hostname.
• Group – Select the name of a group to identify similar devices.
• Interfaces – Enter the IP address of the Linux server.
Here is the new image with our configuration.
Next, we need to associate the host to a monitoring template.
Access the Templates tab on the top of the screen.
Click on the Select button and locate the template named: Template App Elasticsearch Cluster by HTTP
Click on the Add button.
After a few minutes, you will be able to see the initial result on the Zabbix Dashboard.
In order to test your configuration, access the Monitoring menu, and click on the option named: Latest data.
Find your server and click on the Apply button.
Congratulations! You have configured the Zabbix server to monitor an ElasticSearch server.
