I. overview
zabbix is an enterprise-level open source solution based on WEB interface to provide distributed system monitoring and network monitoring functions. zabbix can monitor all kinds of network parameters to ensure the safe operation of the server system, and provide flexible notification mechanism to enable system administrators to quickly locate and solve various problems. zabbix consists of two parts, zabbix server and optional component zabbix agent. zabbix server can provide remote server/network status monitoring, data collection and other functions through SNMP, zabbix agent, ping, port monitoring and other methods. It can run on Linux, Solaris, HP-UX, AIX, Free BSD, Open BSD, OS X and other platforms.

The method of groupid determination:
Click on linux servers
groupid appears in the browser address bar
Tempeid determination method is the same (search filtering can also be used)
Second, monitor apache services
1. Add Host
2, click server2
3, Template > Selection
Add > Update
3. Monitoring database
