Zabbix Installation
Zabbix installation is relatively straightforward and well-documented on the official Zabbix website. It can be deployed in different configurations, depending on your needs. The two primary deployment models are:
Single-node deployment (AIO - All In One): In this setup, all Zabbix components are installed on a single machine. This is suitable for smaller environments or for those who prefer a simpler, less complex installation.
Multinode deployment: This approach is more suitable for larger environments where scalability, fault tolerance, and security are important. In a multinode deployment, Zabbix components are distributed across multiple servers, each handling a specific function. Below are the key components of a multinode Zabbix deployment:
Zabbix Dashboard: This is the web-based interface where system administrators can monitor the status of IT infrastructure, configure the monitoring system, and review performance metrics, alerts, and logs. The Zabbix Dashboard is typically deployed on a public-facing server, and only ports 443 (HTTPS) and 80 (HTTP) are exposed to the public network to ensure secure access. This instance provides access to the main Zabbix interface for users to interact with.
Zabbix Server: This is the core component of the Zabbix monitoring system. The Zabbix server is responsible for processing and storing the monitoring data collected from different hosts. It handles alert generation, event management, and log processing. The Zabbix server interacts with Zabbix agents, proxies, and the database to manage and analyze the collected data, generate reports, and trigger alerts based on predefined thresholds.
Zabbix Database (MySQL): Zabbix uses a relational database to store all monitoring data, configuration settings, and event logs. The database holds historical data for reporting and data retention purposes. In larger deployments, the database can be configured for high availability and redundancy to ensure that data is always accessible and not at risk of being lost. Common database systems used with Zabbix include MySQL, MariaDB, and PostgreSQL.
Zabbix Proxy: In a distributed environment, Zabbix proxies are deployed to offload some of the monitoring workload from the central Zabbix server. Proxies are especially useful for monitoring remote locations or networks that are geographically distributed. They collect data locally from monitored hosts and forward it to the central Zabbix server. Proxies help reduce network load and ensure continuous monitoring, even in cases where direct communication with the central server might be interrupted.
Zabbix Agents: Zabbix agents are installed on the monitored hosts (servers, devices, or virtual machines). These agents collect detailed performance and status data from the host systems, such as CPU usage, memory utilization, disk space, network traffic, and custom application metrics. The Zabbix agents then send this data to the Zabbix server or proxies for further processing and analysis. Agents can run on multiple operating systems, including Linux, Windows, and macOS, and they provide real-time monitoring information to the Zabbix system.
