I can recevied test traps in /tmp/zabbix_traps.tmp but some traps not visable in UI.

[Denny]

When I using ` snmptrap -v2c -cpublic 127.0.0.1 '' SNMPv2-MIB::sysLocation.0 SNMPv2-MIB::sysLocation.0 s "I am here v2c"`
I can see the traps both in /tmp/zabbix_traps.tmp, looks like below output:

22:12:51 2021/07/13 ZBXTRAP 127.0.0.1

.1.3.6.1.2.1.1.6.0 type=4 value=STRING: "I am here v2c"

and UI can also see the output.

But after I configured Nutanix Trap point to Zabbix Server, and click Test botton. I can only see the Test Trap in /tmp/zabbix_traps.tmp. but the traps can not presented in zabbix UI.




I have troubleshooted for couple of days. hope somebody can help.Many Thanks.

Increase the logging level and see what will be in the server (proxy) log when a trap arrives.
(I hope you have a check in the settings to log unmached traps?)

I set debug mode to 3, and I can see below logs:

[Denny]

I have checked the unmatched traps box, but the I still can not see the traps sent from Nutanix Cluster.

[Denny]

attached is the debug log. too many logs. I can't read. I try the Test trap from Nutanix Cluster first then try ` snmptrap -v2c -cpublic 127.0.0.1 '' SNMPv2-MIB::sysLocation.0 SNMPv2-MIB::sysLocation.0 s "I am here v2c"`.

[Hamardaban]

Is there a host "x.x.x.x"? For this, you need to configure the snmp failback or normal snmp item.

[Denny]

x.x.x.x is my prism central. A Prism Central manager many cluster. prism central just like VMware vCenter. I have configure snmpfailbck to catchs all log from prism central.

[Hamardaban]

unmatched trap received from "x.x.x.x"
^^^^^^^^^^

This means that zabbix could not understand which host this trap is intended for.

[Denny]

Is this the root cause why UI can not present traps?
