zabbix presentation

If you want to know the running status of the server in real time and solve problems in time, using monitoring software is a good choice, and zabbix monitoring system stands out among many monitoring software.

Zabbix is an enterprise-level open source monitoring software based on web interface. Zabbix server requires LAMP environment or LNMP environment to provide distributed system monitoring and network monitoring functions. With host performance monitoring, network equipment performance monitoring, database performance monitoring, a variety of alarm methods, detailed reports, charts and other functions. Monitoring objects can be Linux or Windows servers, routers, switches and other network devices, through SNMP, zabbix Agent, PING, port monitoring and other methods to provide remote network servers and other monitoring, data collection and other functions.

zabbix monitoring architecture:

In the production environment, zabbix is divided into three architectures according to external factors such as network environment and monitoring scale: server-client (direct connection), master-node-client (Node architecture) and server-proxy-client (proxy architecture), as shown in the following figure:

1. Server-client architecture: Server-client architecture is the simplest architecture of zabbix. There is no agent between the monitoring machine and the monitored machine, and data interaction is directly carried out between zabbix server (monitoring server) and zabbix agent (agent: deployed on the monitored end, used to collect data). It is suitable for monitoring environments with simple network and few devices. Master-node-client architecture: master-node-client architecture is zabbix's most complex monitoring architecture, suitable for large-scale environments with cross-network, cross-computer room and more equipment. Each node is also a server, node can be connected to proxy, can also be directly connected to client. Node has its own configuration files and database, and all it has to do is synchronize configuration information and monitoring data to master. When the master goes down, nodes ensure the integrity of the architecture. Server-proxy-client architecture: proxy is a bridge between server and client, proxy itself has no front end, and it does not store data, but temporarily stores the data sent by agent d, and then submits it to server. This architecture is often compared to master-node-client architecture, which is generally suitable for monitoring medium-sized network architectures across computer rooms and networks. Zabbix role component Zabbix agent: responsible for deploying on the monitored host and transmitting the monitored host data to zabbix serverZabbix server: responsible for receiving information sent by the agent, organizing configuration information, statistical configuration information and operation data, etc. Zabbix database: database used to store all configuration information of zabbix and monitoring data Zabbix web: zabbix web interface, management can manage zabbix configuration and view zabbix monitoring information through zabbix web interface, can be deployed alone on a server Zabbix proxy: used in distributed environment, zabbix proxy on behalf of the server side manages information collection in this area, and finally unified to zabbix server zabbix communication agent: monitoring through dedicated proxy ssh/Telnet: SNMP: Communication with monitored objects via SNMP protocol, routers and switches support SNMP, which is actually an agentIPMI: Monitoring via IPMI interface, monitoring voltage, temperature, fan, and power status via IPMI hardware interfaces JMX: Monitoring JVM virtual machines via Java management extensions Distributed monitoring architecture: Monitoring data is submitted to zabbix proxy and then submitted to zabbix server

Zabbix working mode Active mode: the agent side actively collects information and sends it to the server side. The tool is zabbix_sender Passive mode: the server side actively pulls information. The tool is zabbix_get.
