SNMP protocol in Logic Machine

[DGrandes]

This happens because there's no error check for get() calls.

Use this code:

Code:

for _, item in ipairs(OID_NAS) do
 vbind, err = ups1:get(item[2])
 if vbind then
   grp.update(item[1], vbind.value)  
 else
   alert('error reading from snmp: ' .. tostring(err))
 end
end

Ok, I´ll try it.

Thanks!!
