Zabbix implementation of web monitoring based on proxy distributed deployment

Objective

In the daily operation and maintenance work, will inevitably encounter such or such a failure, how to find fault in the first time, and timely locate the cause of the failure, to ensure that the business is not affected, I think this should be a good operation must master the skills. But the human can't control the change of the system in real time, so the monitoring system came into being, the monitoring is the eye of operation and maintenance, the operation and maintenance is a very easy thing after the monitoring and performance management is done. At present, the more popular open-source monitoring tools are cacti, Nagios (Icinga), Zabbix and so on. This article brings the Zabbix based on proxy distributed deployment to implement web monitoring.

Zabbix Introduction

Zabbix is an enterprise-class open source solution that provides distributed system monitoring and network monitoring capabilities based on a web interface. It can monitor various network parameters, ensure the safe operation of the server system, and provide a flexible notification mechanism to enable system administrators to quickly locate/solve various problems.

Basic functions

Data acquisition Method: Zabbix agent,agent (Active), SNMP,SSH, etc.

Data storage methods: RDBMS, such as mysql,pgsql, etc.

Data Display method: Php,web,gui

Alarm function: Support alarm Upgrade

Components and infrastructure

Zabbix consists mainly of Zabbix server and Zabbix agent

The server is responsible for collecting monitoring data from the agent and storing it in the database, analyzing and displaying the data, and triggering related alarms.

The agent side is responsible for monitoring the data collection, and sent to the server side

Data acquisition method In addition to the monitoring host on the deployment of the agent program, but also through the ICMP/IPMI/SNMP and other protocols to monitor network equipment, and configure the Web monitoring mode can monitor the Web page download rate and response time and other important parameters

Zabbix Proxy is in a large-scale distributed monitoring scenario, the use of a hierarchical structure to share server pressure, proxy only responsible for a certain area of the data collection, and then periodically sent to the server, which greatly reduces the server load pressure, Enables larger-scale monitoring needs to be supported

Add monitoring

Add Agent

Add monitoring host, select agent monitoring

Add a template

#两台监控主机都执行以上添加操作

Check the monitoring chart to verify that it is monitored

Can already obtain the information of monitoring host, proxy distributed monitoring deployment is successful

Create Web Monitoring

Click Apply Set (applications) to create an app set

Click the Web scene to customize the scene

Create related steps
