zabbix

Basic introduction to Zabbix:

Zabbix is ​​an enterprise-level open source solution that provides distributed system monitoring and network monitoring functions based on a WEB interface. It can monitor various network parameters to ensure the safe operation of the server system; and provides a soft notification mechanism to allow system administrators to quickly locate/solve various problems.

Zabbix consists of 2 parts, zabbix server and optional component zabbix agent.
zabbix server: It can provide monitoring of remote server/network status, data collection and other functions through SNMP, zabbix agent, ping, port monitoring, etc. It can run on Linux, Solaris, HP-UX, AIX, Free BSD, Open BSD , OS X and other platforms.

zabbix agent: It needs to be installed on the monitored target server. It mainly completes the collection of hardware information or operating system-related memory, CPU and other information. zabbix agent can run on Linux, Solaris, HP-UX, AIX, Free BSD, Open BSD, OS X, Tru64/OSF1, Windows NT4.0, Windows 2000/2003/XP/Vista and other systems.

Server: refers to the server where the zabbix service is installed (hereinafter referred to as the server side), which is the most important part. It is mainly installed on the linux system (supporting multiple operating systems), using mysql to store monitoring data and using apache+php. render.

　　Agent: refers to the zabbix agent (hereinafter referred to as the agent) installed on the monitored device. The data on the monitored device is collected by the agent and then uploaded to the server for collection, arrangement and presentation by the server.

　　SNMP: It is also a kind of agent, which refers to a device (or a server) that supports the SNMP protocol. By setting the parameters of SNMP, the relevant monitoring data is transmitted to the server (most network devices such as switches and firewalls support it). SNMP protocol).

　　IPMI: Another method of Agent, which is mainly used for monitoring the physical performance of devices, such as device temperature and fan speed.
