[erlang-questions] Troubles Bridging SNMP and Mnesia

[Martin Bjorklund]

Hi,

Hmm, I didn't look too closely at the error message you got...

This looks weird.  You have a really strange atom
'reporter_server@REDACTED '.  But maybe the <mailto..> part was added
by a clever email program?

Aha!  You cannot use the 2-tuple {node, process} when you store MIB
data.  The erlang data type must match the type defined in the MIB.
If the second column in your MIB is a string, you must store a string
in the Mnesia table.

Hope this helps.
