Zabbix deployment details

Introduction:
Zabbix is an enterprise-level open-source solution that provides distributed system monitoring and network monitoring functions based on the Web interface.
Zabbix can monitor various network parameters to ensure secure operation of server systems. It also provides a flexible notification mechanism for system administrators to quickly locate and solve various problems.
Zabbix consists of two parts: zabbix server and the 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 in Linux, Solaris, HP-UX, aix, Free BSD, open BSD, OS X, and other platforms.
Features:
Main features of zabbix:

• Simple installation and configuration, low learning cost
• Supports multiple languages (including Chinese)
• Free Open Source
• Automatically discover servers and network devices
• Distributed monitoring and centralized web management
• Can be monitored without Agent
• User security authentication and soft authorization Methods
• Set or view monitoring results on the web interface
• Email and other notification functions
  Function:
• CPU load
• Memory usage
  -Disk usage
• Network Conditions
• Port Monitoring
• Log monitoring
  Lab environment:Centos7 (two servers: Monitoring Server and monitored server)
