This article is enough for monitoring systems! Common monitoring tutorials such as Zabbix and Prometheus

Monitoring is commonly known as the "third eye". It is a system that we deal with almost every day. As the saying goes: no monitoring, no operation and maintenance. The status of monitoring is self-evident, especially in operation and maintenance. In the era of automation, traditional operation and maintenance, DevOps, or SRE, monitoring is a necessary skill.

Let’s first get to know the mainstream open source monitoring systems, Zabbix, Open-Falcon, Prometheus, etc. Today we will briefly introduce them[ Zabbix] [Prometheus] [Cacti] [Nagios] [Garafana] and other 5 mainstream monitoring systems for your reference when choosing. In addition, I also share with you the learning materials for these five monitoring systems, so that you can freely learn and refer to them.

All information has been organized into compressed packages

##Prometheus

Prometheus is an open source monitoring system officially released by former Google employees in 2015. Developed using Go language. Not only does it have a cool name, but it also has strong support from Google and k8s, and the open source community is extremely popular.

This Prometheus official Chinese document is suitable for beginners to get started and for students with a certain foundation to advance. This document is divided into seven parts. It starts with the most basic introduction to the installation and startup of Prometheus, and compares the advantages and disadvantages of different monitoring systems, such as Graphite, OpenTSDB, Nagios, etc. In addition, it also includes some practical projects: Grafana combined with Prometheus for visualization, Instrumenting, writing customer libraries, pushing metrics, etc. In short, it is full of useful information!

Part One: LearnPrometheusPreparation

#What is Prometheus? What are the applicable scenarios of Prometheus? PrometheusInstallation and startup, detailed comparison of monitoring system products, this section also lists the Prometheus learning roadmap and vocabulary overview, and recommends some authoritative Prometheus learning medium.

second Part: Detailed explanation of important concepts of Prometheus

In this part, some basic concepts are introduced in detail. Only by studying this part can we truly understand the working principle of Prometheus.

• metrics and labels
• Notation (symbol)
• metrics type
• ##Gauge(measurer)
• Histogram( Bar chart)
• ##Jobs and Instances

Part 3: Query and startup of Prometheus

The next step starts slowly Let’s slowly enter the practical training part. The third part mainly talks about the query and startup of Prometheus,basic concept practical training, and really enters the practical part!

Part 4: Visualization

The main content of this part is to realize the visualization of Prometheus. Teach you step by step how to create a Prometheus Graph using Grafana!

#Zabbix

##Zabbix is ​​a Enterprise-grade, open source, distributed monitoring suite used to monitor the availability and performance of IT infrastructure.

Compared with the above various monitoring systems, Zabbix stands out among the others with its powerful advantages. Its rich functions, scalable capabilities, secondary development capabilities and simple and easy-to-use features greatly enable readers to reduce costs. With no learning costs, you can easily build your own monitoring system.

The Zabbix practical document shared today was compiled by Marco himself and has a total of 141 pages. The content is detailed, theoretical and practical, and full of useful information. I believe that everyone will have a deeper understanding of zabbix after reading it.

#Cacti

##Cacti is a network developed based on PHP, MySQL, SNMP and RRDTool Traffic monitoring graphical analysis tool. Simply put, Cacti is a PHP program. cacti is a very old monitoring tool. In fact, it is more suitable to say that it is a traffic monitoring tool. It is more accurate in traffic monitoring, but it has many shortcomings. The pictures are not good-looking and it does not support distribution.

Regarding the Cacti monitoring system, today I will share a user manual. Including [Use templates to add basic monitoring items for response hosts][Add and monitor custom scripts]
and other contents.
