Zabbix Automation for Host discovery & removal

Zabbix offers automatic network discovery functionality that is effective and very flexible.

With network discovery properly set up you can:

speed up Zabbix deployment
simplify administration
use Zabbix in rapidly changing environments without excessive administration
Zabbix network discovery is based on the following information:

IP ranges
Availability of external services (FTP, SSH, WEB, POP3, IMAP, TCP, etc)
Information received from Zabbix agent (only unencrypted mode is supported)
Information received from SNMP agent
It does NOT provide:

Discovery of network topology
Network discovery basically consists of two phases: discovery and actions.

Discovery
Zabbix periodically scans the IP ranges defined in network discovery rules. The frequency of the check is configurable for each rule individually.

Note that one discovery rule will always be processed by a single discoverer process. The IP range will not be split between multiple discoverer processes.

Each rule has a set of service checks defined to be performed for the IP range.
