What is Zabbix?

Zabbix is an all-in-one monitoring solution designed to track the availability, performance, and health of IT infrastructure. It collects and analyzes metrics from hardware, software, and services, providing actionable insights through graphs, reports, and notifications. Zabbix operates in real time, ensuring that businesses can detect and address problems before they escalate.

The platform supports both agent-based and agentless monitoring, allowing users to gather metrics from various sources using native Zabbix agents or standard protocols such as SNMP, IPMI, and JMX. With a highly customizable interface, Zabbix enables teams to create dashboards tailored to their specific needs. It is suitable for environments of all sizes, from small setups to large-scale enterprise deployments.

10. Enhanced Security Features
    Implement role-based access control (RBAC), encrypted communications, and secure authentication to protect sensitive data.

How Zabbix Works and Architecture

How It Works:
Zabbix collects performance data from monitored devices and compares it against predefined thresholds. Alerts are triggered when these thresholds are breached, and data is stored for analysis and visualization.

Architecture Overview:

1. Zabbix Server:
   Acts as the core of the system, responsible for data collection, storage, and processing.
2. Database:
   Stores configuration data, metrics, events, and historical data for analysis.
3. Zabbix Agents:
   Installed on monitored devices to collect detailed metrics and send them to the Zabbix server.
4. Proxies:
   Used to scale monitoring by offloading data collection and preprocessing in distributed environments.
5. Frontend (Web Interface):
   Provides a user-friendly dashboard for configuring monitoring, visualizing data, and managing alerts.
6. Alerting System:
   Configures triggers and actions to notify users of critical issues.

How to Install Zabbix

Steps to Install Zabbix on Linux:

1. Update the System:

sudo apt update && sudo apt upgrade

2. Add Zabbix Repository: Download and add the Zabbix repository to your package manager:

wget https://repo.zabbix.com/zabbix/6.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_6.0-1+ubuntu20.04_all.deb
sudo dpkg -i zabbix-release_6.0-1+ubuntu20.04_all.deb
sudo apt update

3. Install Zabbix Server, Frontend, and Agent:

sudo apt install zabbix-server-mysql zabbix-frontend-php zabbix-apache-conf zabbix-agent

4. Configure Database:

• Create a Zabbix database:

CREATE DATABASE zabbix CHARACTER SET utf8mb4 COLLATE utf8mb4_bin;
CREATE USER 'zabbix'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON zabbix.* TO 'zabbix'@'localhost';
FLUSH PRIVILEGES;

• Import the database schema:

zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -u zabbix -p zabbix

5. Start Zabbix Services:

sudo systemctl start zabbix-server zabbix-agent apache2
sudo systemctl enable zabbix-server zabbix-agent apache2

6. Access Zabbix Dashboard: Open your browser and navigate to http://<server_ip>/zabbix. Complete the installation wizard by connecting to the database and setting an admin password.
