1 Introduction
Linux system monitoring has always been a difficult problem. Many companies or organizations choose to set up their own monitoring systems for application performance monitoring, server resource monitoring, etc. However, this undoubtedly increases the cost and workload of operation and maintenance personnel, and also limits the Monitoring performance and scalability. In order to reduce the complexity of Linux system monitoring, improve efficiency, and improve accuracy, more and more companies, organizations, and individuals are beginning to pay attention to full-stack monitoring solutions based on open source solutions, open source data collection tools, and open source monitoring systems, such as Zabbix, Prometheus, Grafana, Fluentd, ELK Stack, Nagios, etc.
Today I will combine the author's many years of system monitoring experience to introduce the architecture and core components of Linux system monitoring from a macro perspective. I will also introduce the various levels and corresponding functions of the monitoring system based on Zabbix, the most well-known monitoring system in the open source community. I hope to be able to Give readers a more comprehensive understanding.
2. System architecture
2.1 Zabbix Overview
Zabbix is an open source monitoring system based on the GPLv2 protocol. It was developed by Zabbix SIA, a German IT consulting company. It is currently one of the most popular open source monitoring systems in the world. It has powerful features and stability and is widely deployed in enterprise environments. Its main features include:
- Supports many mainstream hardware monitoring (such as server hardware, network equipment, storage devices, etc.), and provides a rich template library to support various forms of automated management;
- Provides a WEB front-end interface to facilitate users to view monitoring information;
- Supports user rights management, allowing fine-grained control of user access rights to various types of data;
- Supports multiple data collection methods, including SNMP, IPMI, JMX and other protocols;
- Supports multiple data sources and can collect different data sources to the same platform to achieve a unified monitoring view;
- Support graphic report display &
