Nut upsdev - Nov 2011 - Adding power devices support to OCS Inventory NG

Dear OCS fellows,

I've been thinking about working on adding power devices knowledge to OCS
for years.
Following the last Ubuntu Developer Summit, I know have an "excuse" to
do
so:
https://blueprints.launchpad.net/ubuntu/+spec/servercloud-p-cloud-power-management

My below proposition is related to the above blueprint. So please keep in
mind that the target is also to be able to provide these info to OCS, so
that it can in turn provide these to Cobbler / Orchestra.

Power devices are UPS, PDU, server power supplies and solar controllers, as
supported by the Network UPS Tools (NUT) project.
NUT is the major free software for dealing with such devices:
http://www.networkupstools.org/

NUT has some internal automation that allows to extract these information
(USB IDs, SNMP sysOIDs, IPMI PSU,...) from the drivers (so no declaration
redundancy), in order to generate support files (udev, upower, ...) or
tools such as the NUT scanner:
http://www.networkupstools.org/docs/man/nut-scanner.html

So, would you be interested in working with me on this topic?
How can we proceed?
Which kind of integration would be best, ie providing a formated files, or
using languages binding or program calls?

cheers,
Arnaud

Hi Arnaud,

Thanks a lot for your email. Of course, we are interested to work with you on
this. It could be really interesting to get this kind of informations in OCS
Inventory.

If the "nut-scanner" command can use SNMP, an idea could be to
integrate it directly in OCS SNMP scans steps. A special perl module could be
create to make OCS agent able to scan NUT devices during its SNMP scans. I think
it could be easily integrated. If you want, you can take a look at OCS Unix
agent trunk branch on launchpad
(https://code.launchpad.net/~ocsinventory-dev/ocsinventory-unix-agent/trunk) and
take a look to lib/Ocsinventory/Agent/Modules/Snmp* files to give you an idea on
how SNMP scans work.

Of course, it is a first idea and there is surely an other way to do this :) :).

Kind regards,

Guillaume
