this is the right answer. The mib autodetection hasn't yet been
implemented in snmp-ups.

Moreover, you have to know that snmp-ups is still experimental for one
main reason (at least for MGE): the manager mode, which allows a
manager (like snmp-ups) to register itself in the agent (ie the card)
so that the card knows there are client(s) connected when it comes to
shutdown time.
This means that you will have to launch the shutdown a bit earlier
before battery.charge = battery.charge.low (using upssched).
Otherwise, the UPS will cut its output, and crash the protected

I hope this will answer your questions.
