Zabbix: The Ultimate Open-Source Monitoring Solution for Your Infrastructure

Monitoring and managing your networks, systems, and applications can be a challenging task without the right tools. However, with Zabbix, a powerful open-source monitoring solution, you can keep track of your infrastructure and ensure everything is up and running at all times.

In this article, we will explore Zabbix’s various features, including how to install and configure it on CentOS 7, monitor metrics, set up notification alerts, and much more. Let’s dive in!

Installing and Configuring Zabbix Server on CentOS 7

First things first, you need to install Zabbix on your CentOS 7 machine. Here’s what you need to do:

Creating MySQL Database

Before you install Zabbix, you need to create a MySQL database. You can use either MariaDB or MySQL, whichever you are comfortable with.

Here’s how you can do it using the SQL command:

– Log in to MySQL: “mysql -u root -p”

– Create a database: “CREATE DATABASE zabbixdb;”

– Create a user: “GRANT ALL PRIVILEGES ON zabbixdb.* TO zabbixuser@localhost IDENTIFIED BY ‘password’;”

– Exit MySQL: “exit”

Installing Zabbix on CentOS

Next, you need to add the Zabbix repository and install the packages. Here’s how you can do it:

– Add the repository: “rpm -ivh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm”

– Install Zabbix server, frontend and agent: “yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent”

Configuring PHP for Zabbix frontend

To run the Zabbix frontend, you need to configure PHP. Here’s how you can do it:

– Open the PHP configuration file: “vi /etc/php.ini”

– Find “date.timezone” and set it to your timezone: “date.timezone = America/New_York”

– Save and exit the file

Configuring the MySQL Database for Zabbix Server

After installing Zabbix, you must configure the MySQL database for the Zabbix server. Here’s how you can do it:

– Import the schema and data: “zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbixuser -p zabbixdb”

– Configure your database details in the Zabbix configuration file: “vi /etc/zabbix/zabbix_server.conf”

– Enter the username, password, and database name for the MySQL server

– Save and exit the file

Installing and Configuring Zabbix Frontend

Finally, you can install and configure the Zabbix frontend using these steps:

– Edit the Apache configuration file: “vi /etc/httpd/conf.d/zabbix.conf”

– Add the following line: “php_value max_execution_time 300” (This increases the maximum execution time for PHP scripts to 300 seconds)

– Restart Apache: “systemctl restart httpd”

– Visit the Zabbix web interface on your web browser: “http://ip-address/zabbix”

– Follow the pre-installation summary to complete the installation

– Login to the user profile page to set up alerts, notifications, and more

Adding a New Host to Zabbix Server

Now that you have installed and configured Zabbix, it’s time to add a new host. Here’s how you can do it:

– Install the Zabbix agent on the host you want to monitor

– Set the PSK method for the Zabbix agent

– Set up a firewall rule on the host to allow the Zabbix server to connect via port 10050

– Register the new host on the Zabbix server

Zabbix Features

Now that you have set up Zabbix, you can start monitoring your networks, systems, and applications. Let’s explore some of Zabbix’s key features:

Monitoring Metrics

Zabbix allows you to monitor various metrics, including network devices, systems, and applications. You can see whether everything is working correctly, whether they need maintenance or upgrade, and whether they are exceeding their threshold levels.

Notification Alerts

Zabbix can send notification alerts to your email, SMS, or any other preferred method. Once you set it up, you can receive alerts whenever a problem arises to ensure you can address it quickly.

Agent-based and Agent-less Monitoring

Zabbix offers both agent-based and agent-less monitoring options. You can use the Zabbix agent, which has a small footprint, on systems or applications, or opt for agent-less monitoring, which is ideal for network devices.

Platform Compatibility

Zabbix is compatible with various platforms, including Linux, UNIX, macOS, and even Windows. Hence, you can monitor your entire infrastructure regardless of the operating system in use.

Open-source Monitoring Software

Lastly, Zabbix is an open-source monitoring software, which means anyone can use it. It’s also completely free and customizable, allowing you to tailor it to your exact needs and preferences.
