Problem getting information in zabbix Latest data for snmp trap.

[Anton Semashka]

Hello everyone! Has anyone encountered a problem with getting information about snmp trap in Latest data?

I set up snmp trap in zabbix using a guide with a pl script. When I send a test message "snmptrap -v 2c -c linux localhost '' SNMPv2-MIB::snmpMIB IF-MIB::linkDown s ens3", then as expected I get a message in the snmptrap.log and the latest data in zabbix.

But when testing and sending from the device, I get information in snmptrap.log and zabbix.log, but not in the latest data inside zabbix. What could be the problem?

Item config?

In the settings, I disabled the community to accept all traps and configured the item host as follows:

https://www.zabbix.com/documentation...types/snmptrap Configuring SNMP traps

This item type requires the following frontend configuration.

1. Create an SNMP interface for your host

• In Data collection > Hosts, create/edit the host, and in the Interfaces field, add the interface type "SNMP", specifying the IP or DNS address.
  
  The address from each received trap will be compared to the IP and DNS addresses of all SNMP interfaces to find the corresponding hosts.

So your testing from your zabbix server works probbly because of 127.0.0.1...

and fallback does not catch those coming from outside... (That interface is 127.0.0.1 at the moment)

snmptrap.fallback

Catches all SNMP traps that were not caught by any of the snmptrap[] items for that interface.

you need to create a host with the correct IP/DNS in interface config...

I need to set up a host for the zabbix server in the interfaces not 127.0.0.1, but its address looking into the network?

Or create a host with ip from which traps are sent?

Thats what I said...

Thank you. It actually worked. There was probably a mistake in the instructions.
