This means it failed to get all the information via SNMP (the
$session->get_request() failed).

.1.3.6.1.3.94.1.6.1.20.1 is just one part of %apcoids, listed in the
source as;

  'name' => '.1.3.6.1.3.94.1.6.1.20.1',
  # RFC1155-SMI::experimental.94.1.6.1.20.1
  # string: full name of the UPS

You're not making sense and not reading the source correctly.

%apcoids stores all the OIDs and gives them a named reference so they
are more human readable and can be changed or updated easily.

The $session->get_request() call requests the information stored at
the listed OIDs, into $apcoids{} and from there it is parsed and tested.


My source for the OIDs was, as listed in the source;
  http://www.apcc.com/tools/download/software_comp.cfm?sw_sku=sdw99.3.6.1
along with snmpwalk-ing the UPS to see what was there.

The error you listed comes from a failure to get the SNMP data for all
the OIDs listed in %apcoid (there are 10 of them, not just
.1.3.6.1.3.94.1.6.1.20.1). I can't tell you why that failure is
happening with that little information, could be any one of a dozen
different things...

If your UPS doesn't have some of the OIDs used (which is impossible
for me to tell, you'd have to test) then take them out of the list and
remove the checks on them. Or upgrade your UPS's network card firmware
(which I'd strongly advise anyway since there have been lots of
problems with older firmware) to see if they get added.
