Hi,
It seems SNMP trap receiver truncates some values

Above is log from netxms. Below i am attaching snap from trapviewer software. Which shows correct values .
I can see the hex values are cut/discarded in netxms

It's not the trap receiver, but event processing. Currently event's message size limited to 255 characters. Because default event just put everything into message it gets truncated. Usually you will create separate events for traps of interest, and you can carry trap arguments as event parameters, and then use them in actions, for example, without length limitations.

To receive Traps, i hadnt configure any event .
Does it automatically calls Default Event?

Can you give an example for argument passing ?
