LLD snmp external check

[platine]

hi,

Maybe someone can help me.
I've created a template with a discovery rule by external check script (SNMP). All of that work perfectly until i associate this template with a host witch has one ip for zabbix agent and one other for snmp checks.
My script always receive only agent's ip ... i have tested with {HOST.CONN},{HOST.CONN2}, {HOST.IP2} ...
Is there a way to choose snmp ip instead of agent ip in external check's key ?

Ahhh, yes.
Your LLD rule has to be of type "SNMP v{1/2/3} agent".
Then it uses the (hopefully) defined SNMP interface.

thank you, i will test this when my zappix's project will restart

hi,
i've tested but i can't do that.
I've this problem when discovery rule is executed not when created item is checked.
Discovery rule is done with "agent's ip" instead of "SNMP's ip" and i would like to discovery with "SNMP's IP".

It is done that way by design:

since 2.2.0 the macro will use the main agent interface, however, if it is not present, the main SNMP interface will be used. If SNMP is also not present, the main JMX interface will be used. If JMX is not present either, the main IPMI interface will be used. In item key parameters the interface that is selected for the item will be used, since 2.0.3.

Sorry, I obviously don't get the point.
Zabbix items are executed against the defined "Zabbix IP" (agent interface) while SNMP checks are executed against the defined SNMP interface. So you should be able to have different IP addresses for "Zabbix agent" and "SNMP interface"
