Re: [eman] EMAN-REQ: the notion of importance

-1

If you remove context variables such as role: what a device is use for,
and a way to compare devices (importance) how will you determine which
ones you can shed power usage from in times of peak.

I agree this is something that should be in general network management.
Fault correlation and problem tracking would be easier. For power
management of a system the notion of context becomes more critical. For
example if during a peak demand time you want to shed power from you
lighting system and you have no notion of context how would you
determine which lights were decorative, emergency, task, or ambient
lights? 

The argument that this should be in the management system can be said
for any attribute, it becomes more useful if the devices have these
attributes in them. 

For example compare this to location attributes. You could argue that a
device need not have  a location attribute and this is part of the NMS -
but look at the usefulness of systems that have been developed when a
standardized location is put in the devices themselves versus a central
NMS.

If you remove context you remove any notion of being able to have
devices work on their own or in concert to control power. You relegate
it to a central system which will become proprietary an intractable with
the IoT.

So if you remove this you remove the core usefulness of the system.

Hi,

I agree. I personally also think that importance can be removed. It is
ill defined in the current document, if _really_ needed it seems like a
more general concept and I wonder why it should be part of the MIB as
opposed to something that is part of the management system. Regarding
role, if it is to stay in the MIB (as opposed to the EnMS) then it also
need a better definition and a good justification why it should be
stored on the device itself.

Best,

Rolf
