How to read snmptrap for monitoring

[raid3868]

Dear All

All zabbix experts need help on how to read snmptrap for monitoring in zabbix 4.
Currently one of my 8 port switch is sending out snmp trap to my zabbix 4 server and i have configured zabbix to receive trap and my trap file is stored at /tmp/zabbix_traps.tmp
at zabbix host i have created Template SNMP Trap fallback: SNMP Trap fallback and Trigger Template SNMP trap fallback: Unmatched SNMP trap received from {HOST.NAME} {192.168.1.10.switch.local.com:snmptrap.fallback.n odata(300)}=10

I can see the data at /tmp/zabbix_traps.tmp and also at monitoring but have no idea to read to zabbix for monitoring, graph .

Many thanks if experts can help.

Dear raid3868,
we can monitor the snmptrap using zabbix through SNMP Interfaces.
I would recommend you to follow the following steps:-
1. create Host by adding SNMP interfaces
2.create item with Type:- SNMP trap, key:- snmptrap.fallback, Type of information:- Log
3. change /etc/zabbix/zabbix_server.conf
StartSNMPTrapper=1
SNMPTrapperFile= [TRAP FILE]
4.Restart Zabbix service
5. Check the output in Monitoring, latest data.

Please Do let me know if your issue is not resolved.

Dear Maishk

Many Many Thank for you fast reply.

I have all done this step. I can view the data at zabbix > monitoring > latest data > mysnmptraphost -> history

This is a 8 port switch and i think IF-MIB::ifHCInOctets.30 is represent a port my question is how can i read this to zabbix with every IF-MIB::ifHCInOctets as a individual item
so i can keep their history.

example: this one of my cisco switch

			Interface gi27(): Bits sent	2019-07-25 15:26:53	436.5 Kbps	+311.62 Kbps	Graph
			Interface gi27(): Bits received	2019-07-25 15:26:53	26.6 Kbps	+10.95 Kbps	Graph

Thanks you very very much

"SNMP traps" and "SNMP get" are two big differences.

[Hamardaban]

No graph because the data is trap - string type. You can't build graphs on string values. But for example, you can make a calculated data item with the formula count("snmptrap.fallback",300) - number of traps for 5 minutes. And watch this chart.

Or use preprocessing to extract the values and convert it to numeric

Or use depended items with regex to the same purpose
