Zabbix is a comprehensive open-source monitoring solution designed to monitor and track the status of various network services, servers, and other network hardware. This tool plays a pivotal role in the DevOps methodology, providing real-time monitoring of thousands of metrics collected from different types of servers and supporting the dynamic environments that are characteristic of DevOps.
DevOps, a portmanteau of 'development' and 'operations', is a set of practices that combines software development and IT operations. It aims to shorten the system development life cycle and provide continuous delivery with high software quality. Zabbix, as a monitoring tool, fits seamlessly into this framework, providing the necessary visibility and feedback loops that DevOps principles advocate for.
Definition of Zabbix
Zabbix is an enterprise-class open-source distributed monitoring solution designed to monitor and track performance and availability of network servers, devices, services and other IT resources. It is capable of monitoring millions of metrics, such as CPU load, network utilization and disk space consumption from tens of thousands of servers, virtual machines and network devices simultaneously.
Developed by Alexei Vladishev, Zabbix uses MySQL, PostgreSQL, SQLite, Oracle or IBM DB2 to store data. Its backend is written in C and the web frontend is written in PHP. Zabbix offers several monitoring options, including checking if a specific service response on a specific port, pinging the system, or checking for specific values (like CPU usage, disk usage, etc.) in the system's SNMP tree.
Zabbix Architecture
Zabbix operates on a client-server model. The Zabbix server actively checks Zabbix agents (software modules installed on IT assets that need to be monitored) and collects data. The server can check standard parameters like network utilization, CPU load, etc., but also can check custom parameters based on user-defined scripts. The server is the central component to which agents report availability or any issues they encounter.
The Zabbix web interface is a part of the Zabbix software. It is used to manage resources under monitoring and view monitoring results. Zabbix web interface is written in PHP and JavaScript. It communicates with the backend API to retrieve and send data to the database.
DevOps and Zabbix
DevOps is a set of practices that combines software development (Dev) and IT operations (Ops), with the goal of shortening the system development life cycle and providing continuous delivery with high software quality. Zabbix, as a monitoring tool, fits seamlessly into this framework, providing the necessary visibility and feedback loops that DevOps principles advocate for.
Monitoring is a crucial aspect of the DevOps approach. It provides the visibility required for maintaining the performance and availability of the applications and infrastructure that DevOps teams are responsible for. Zabbix, with its real-time monitoring capabilities, provides this visibility, making it an essential tool in a DevOps environment.
Continuous Monitoring with Zabbix
Continuous monitoring is a method to detect, report, respond, and prevent security issues in a timely manner. It provides transparency into IT infrastructure, enabling teams to detect and fix issues faster. Zabbix's comprehensive set of features allows for continuous monitoring of servers, virtual machines, networks, and cloud services, providing teams with real-time information about their IT infrastructure.
With Zabbix, teams can set up automated alerts to notify them of any issues or anomalies. This allows for quick resolution of issues, minimizing downtime and ensuring the smooth operation of services. Furthermore, Zabbix's performance metrics and trend prediction features allow teams to proactively manage their IT infrastructure, preventing issues before they occur.
History of Zabbix
Zabbix was created by Alexei Vladishev, who currently serves as the CEO of Zabbix LLC, which provides a wide range of professional services such as technical and consultative support, Zabbix integration, implementation and customized development services as well as Zabbix professional training. The first public version of Zabbix was released in 2001 and it has been in active development ever since.
Over the years, Zabbix has grown and evolved to meet the changing needs of businesses. It has expanded its functionality to include service monitoring, SLA, reporting, and more. Today, it is used by businesses of all sizes, from small startups to large enterprises, and is recognized as a leading open-source monitoring solution.
Notable Milestones in Zabbix History
In 2005, Zabbix 1.0 was released, marking the first stable release of the software. This version included basic monitoring capabilities, such as checking availability and responsiveness of standard services like HTTP, FTP, SMTP, POP3.
In 2007, Zabbix 1.4 was released, introducing a host of new features, including a web monitoring module for end-to-end web application monitoring and network discovery functionality. In 2010, Zabbix 1.8 was released, which included new features like JMX monitoring, web scenario support, and expanded SNMP monitoring.
Use Cases of Zabbix
Zabbix is used in a wide variety of contexts, due to its flexibility, scalability, and comprehensive feature set. Some common use cases include network monitoring, server monitoring, cloud monitoring, application monitoring, and service level agreement (SLA) monitoring.
For network monitoring, Zabbix provides tools to visualize your network on the map and use the map to track statuses of various network devices. In addition, Zabbix supports SNMP, TCP and ICMP checks, and allows you to configure IP range to scan your network and automatically add network devices to the system.
Server Monitoring
For server monitoring, Zabbix can collect metrics from servers, such as CPU usage, memory usage, disk I/O, network traffic, and more. This data can be displayed in a variety of formats, including graphs, charts, and tables. In addition, Zabbix can send notifications and alerts based on predefined thresholds, ensuring that you are aware of any potential issues before they become critical.
Zabbix supports both polling and trapping methods for collecting data from monitored hosts. Polling is a method where Zabbix server or proxy requests certain information from a device, and the device responds with the requested information. Trapping is a method where a device sends information to Zabbix server or proxy on its own initiative without any request.
Cloud Monitoring
With the rise of cloud computing, Zabbix has also become a popular tool for monitoring cloud services. It can monitor various aspects of your cloud infrastructure, including virtual machines, databases, storage, network traffic, and more. This can help you ensure that your cloud services are performing optimally and are available when needed.
Zabbix provides out-of-the-box templates for monitoring popular cloud services such as Amazon AWS, Google Cloud, and Microsoft Azure. These templates include checks for a wide variety of metrics, allowing you to monitor the health and performance of your cloud services in a comprehensive manner.
Examples of Zabbix in Action
Zabbix has been successfully used in various industries and for various purposes. Here are a few examples of how Zabbix has been used to monitor and manage IT infrastructures.
