Oh, I know. But it should give the UPS a better idea of how long it can *actually* support that load, and for this purpose that's good enough for me. >> In particular, no load, no input or output voltage.

This is Gentoo Linux so it's built from the latest source version in the repository. I would tend to make the same assumption about the RM205 vs. the RM202. > You can also use snmpwalk to see what other values might be available. > Since there is already a skeleton MIB mapping in NUT, the only two > things needed are probably the snmpwalk outputs described at the end of > this > section: > https://networkupstools.org/docs/developer-guide.chunked/ar01s04.html#snmp-subdrivers > >> (Also, I can so far connect only using snmpv1, but I don't know whether >> I should expect to get any additional data from snmpv3 anyway.) > > Again, not my area of expertise, but as far as NUT is concerned, I think > the different versions are for authentication methods (SNMPv1 is cleartext). I actually switched to the usbhid-ups driver, and it is working far better than the snmp driver did. I just need a small USB hub now, because there's only two back-panel USB ports on this server and I now need three (KVM, GPS receiver, and UPS). -- Phil Stracchino Babylon Communications ph...@caerllewys.net p...@co.ordinate.org Landline: +1.603.293.8485 Mobile: +1.603.998.6958 _______________________________________________ Nut-upsuser mailing list Nut-upsuser@alioth-lists.debian.net https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
