4 Network discovery rule
Network discovery rule is a rule used by Zabbix to discover hosts and services.
Parameters of network discovery rule:
| Parameter | Description |
|---|---|
| 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 List: 192.168.1.1-255,192.168.2.1-100,192.168.2.200,192.168.4.0/24 |
| 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 List: 22-45,55,60-70 |
| 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.
