Hello
We have an Socomec Sicon Netys PR3000 UPS equipped with NetVision
Web/SNMP adaptor. I try to monitor the ups using snmp-ups driver and
netvision mibs set. The snmp-ups driver starts correctly and connects to
the UPS, upsd confirms it, but upsmon constantly shows "No
communication" error
I think the cause is the SNMP adapter reports the UPS status as "ECO
mode" (snmpget .1.3.6.1.4.1.4555.1.1.1.1.4.1.0 returns 9), but snmp-ups
does not correctly process this. Here is output of 'snmp-ups -a socomec
-u nut -D':

And 'upsmon -u nut -DDD' output:
Network UPS Tools upsmon 2.6.1
0.000000 UPS: socomec@localhost (master) (power value 1)
0.000090 Using power down flag file /etc/killpower
0.000213 debug level is '3'
0.000705 Trying to connect to UPS [socomec@localhost]

0.001209 do_notify: ntype 0x0005 (COMMBAD)
0.001220 Communication with the UPS is lost
In netvision-mib.c I see that ups.status field is constructed from
NETVISION_OID_BATTERYSTATUS (.1.3.6.1.4.1.4555.1.1.1.1.2.1.0) and
NETVISION_OID_OUTPUT_SOURCE (.1.3.6.1.4.1.4555.1.1.1.1.4.1.0).
Battery status is normal (value 2), value for netvision_batt_info is ""
(empty string). Good.
Output status has value 9, netvision_output_info is empty string too.
Looks false because the UPS is on and works in high-efficiency UPS mode.
The result is that ups.status get an empty string value, which confuses
upsmon.
