Network discovery rule is a rule used by Zabbix to discover hosts and services.
Parameters of network discovery rule:
|Name||Name of the rule. For example, "Local network".|
|IP range||Range of IP addresses for discovery. It may have the following formats:
Single IP: 192.168.1.33
Range of IP addresses: 192.168.1.1-255
IP mask: 192.168.4.0/24
supported IP masks:
/16 - /30 for IPv4 addresses
/112 - /128 for IPv6 addresses
|Delay (in sec)||This parameter defines how often Zabbix should execute this rule.|
|Checks||Zabbix will use this list of checks for discovery of hosts and services.
List of supported checks: SSH, LDAP, SMTP, FTP, HTTP, POP, NNTP, IMAP, TCP, ZABBIX Agent, SNMPv1 Agent, SNMPv2 Agent, SNMPv3 Agent
Parameter Ports may be one of following:
Single port: 22
Range of ports: 22-45
|Device uniqueness criteria||Uniqueness criteria may be:
IP address (no processing multiple-IP devices)
One of discovery check of the rule. Will be based either on a SNMP or Zabbix Agent check.
|Status||Active – the rule is active and will be execute by Zabbix server
Disabled – the rule is not active. It won't be executed.
Each IP address should be included only once, having multiple rules for a single IP address can have unexpected behaviour such as having deadlocks and/or duplicate hosts in the database. The same could happen if two hosts having the same DNS name are included in separate discovery rules.
