Key values

[MichaelF]

Hello!
While learning the snmp discovery I've seen (both in the book and on the site) only the examples with discovering network interfaces and creating the interface item prototypes (Discovery rule: Key: snmp.interface.discovery and the item prototype: ifInOctets[{#IFDESCR}] / OID:IF-MIB::ifInOctets.{#SNMPINDEX}). But many Zabbix templates contain discovery rules for many other hardware: fans, psu etc, for example, the discovery rule - fan.discovery, psu.discovery, item prototypes: sensor.fan.status[swFanStatus.{#SNMPINDEX}], sensor.psu.status[swPowerStatus.{#SNMPINDEX}].

The question: how can I know which keys may be used in the discovery rules and the item prototypes?

Thank you in advance,
Michael

I don't know if i understood you ...
But have you checked the Discovery item on your template?

If we are talking about low level discovery - all discovery rules supported by zabbix agent are documented under https://www.zabbix.com/documentation...s/zabbix_agent.
Items used as for discovery are named *.discovery. Usually they receive JSON from agent.
You can check what these rules return by using zabbix agent

# zabbix_agent2 -t net.if.discovery
net.if.discovery [s|[{"{#IFNAME}":"vetha0c08ca"},{"{#IFNAME}":"br-a3da5d0f6a8b"},{"{#IFNAME}":"veth0f4c96f"},{"{#IFN AME}":"docker0"},{"{#IFNAME}":"br-46138826b3d4"},{"{#IFNAME}":"br-b974bccd28be"},{"{#IFNAME}":"br-f0b94bc9fa89"},{"{#IFNAME}":"veth26dc8ab"},{"{#IFN AME}":"vethe69e59f"},{"{#IFNAME}":"br-cc0c3782c7bb"},{"{#IFNAME}":"br-74cd60776f6c"},{"{#IFNAME}":"eth0"},{"{#IFNAME}":" veth2bd39d6"},{"{#IFNAME}":"br-3131fe4ee93f"},{"{#IFNAME}":"vetheb613c6"},{"{#IFN AME}":"vethe05699a"},{"{#IFNAME}":"vethebe9c47"},{ "{#IFNAME}":"vetha32f860"},{"{#IFNAME}":"lo"}]]

Some templates receive discovery via API calls - these are device specific.
And you can create your own completely discovery rules as well.
