From this post and the video, you will learn more about the most common troubleshooting steps to resolve any proxy issues and to detect them as sometimes you might be unaware of an ongoing issue, as well as basic performance tuning to prevent such issues in the future. (This is configured by "Log unmatched SNMP traps" in Administration General Other.). notificationtype TRAP I'm trying to create a generic Event (called Problem in zabbix) from any unmatched SNMP trap received for any device, which will basically consist only from host IP a some text like "unknown trap" or even the full text of a trap as its received by FallBack. Otherwise process traps normally untill the last one, which again should be kept in read buffer until the next attempt. is there a way to avoid this ? This is very important, since, for some reason I can't explain, if you use a HOSTNAME as the ID, Zabbix will not match the TRAP with the host and will write on Log file: "unmatched trap received from." How to use. Configuring the following fields in the frontend is specific for this item type: In Data collection Hosts, in the Host interface field set an SNMP interface with the correct IP or DNS address. Problem expression for triggering an interface down event for interface index 5 of host Switch: Recovery expression for the same trigger: Note that in order to Zabbix to link the incoming trap to the correct host the host in Zabbix needs to have an SNMP interface configured with the same IP address that the trap contains. 6.
