Zabbix implements Web monitoring based on Proxy distributed deployment
Preface

In daily O & M work, it is inevitable that one or more failures will occur. How can we find the fault in the first place and locate the Fault Cause in time to ensure that the business is not affected, I think this should be a skill that must be mastered in O & M. However, human resources cannot control system changes in real time, so the monitoring system emerged. monitoring is the eye of O & M. After monitoring and performance management are completed, O & M is a very easy task. Currently, popular open-source monitoring tools include Cacti, Nagios (Icinga), and Zabbix. In this article, Zabbix implements Web monitoring based on Proxy distributed deployment.

Zabbix Introduction

Zabbix is an enterprise-level open-source solution that provides distributed system monitoring and network monitoring functions based on the Web interface. It monitors various network parameters, ensures secure operation of server systems, and provides a flexible notification mechanism for system administrators to quickly locate and solve various problems.

Basic functions

Data collection methods: zabbix agent, agent (active), SNMP, SSH, etc.

Data Storage Methods: RDBMS, such as MySQL and Pgsql

Data Presentation Methods: php, web, and gui

Alarm function: supports alarm escalation

Components and infrastructure

Zabbix consists of zabbix server and zabbix agent.

The server collects monitoring data from the agent, stores the data in the database, analyzes and displays the data, and triggers related alarms.

The agent collects monitoring data and sends it to the server.

In addition to deploying the agent program on the monitored host, the data collection method can also monitor network devices through ICMP, IPMI, SNMP, and other protocols, you can also configure the web monitoring method to monitor important parameters such as the download rate and response time on the web page.

Zabbix proxy is a layered structure used to share the pressure on the server in large-scale distributed monitoring scenarios. The Proxy is only responsible for data collection in a certain area, then, the data is periodically sent to the server at a time, which greatly reduces the load pressure on the server and supports large-scale monitoring.

Some Zabbix Tutorials:

Compile and install Zabbix2.4.5 source code in Ubuntu 14.04

Install and deploy the distributed monitoring system Zabbix 2.06

Install and deploy the distributed monitoring system Zabbix 2.06

Install and deploy Zabbix in CentOS 6.3

Zabbix distributed monitoring system practice

Under CentOS 6.3, Zabbix monitors apache server-status

Monitoring MySQL database Parameters Using Zabbix in CentOS 6.3

Install Zabbix 2.0.6 in 64-bit CentOS 6.2

Implement Process Experiment Topology

# System environment: CentOS6.6 # Zabbix Server is LAMP environment # Zabbix Proxy requires database support # Zabbix Server and Zabbix Proxy need time synchronization, all nodes have been synchronized

The logon interface is as follows. The default user is admin and the password is zabbix.

Zabbix2.4 disables Chinese display by default.
