That's probably because icmp is not defined in this mib file.  It will
be defined in mib2 which is included by default.


Check the first line of the log file (1.2.3.4-icmp.log) to see if that
changes.  If it doesn't, data collection fails.  If it does change, there
is something wrong in your configuration file.  Failure to collect the
data can happen under several circumstances as described further on (one
other reason, connectivity problems, you have already ruled out).

Perhaps you need to specify the full OIDs but I think this isn't necessary
anymore with recent versions of the SNMP package used by MRTG.

I may be wrong on this but I think "perminute" and "gauge" should not
be combined.  If you want to display the value of the counter, you
should use "gauge".  If you want to display the increase of the counter
(the delta) you should NOT use "gauge".  The "perminute" option is used
to change the default behaviour from "increase per second" into per
minute and is therefore incompatible with "gauge".

Wouldn't this discard any value > 192000?
