This is interesting as it is a topic that I brought up just before UDS-O
with my support colleagues. This might be somewhat off-topic with Nick's
request, but close enough to the topic to be worth mentioning.

Right now, unlike other enterprise distributions, no performance data of
any kind is collected automatically. While this is understandable on a
Desktop system, such data is quite useful in on a server.

Especially when time comes to deal with customer complains on the fact
that  such and such upgrade did have a negative impact on performances.
Without historical performance data, investigation of such claims are
almost impossible.

Some distributions have used SAR, which is part of sysstat. Other
lightweight solutions exists, like collectl (L and not D) which lives at
http://collectl.sourceforge.net. Those two only take care of collecting
the data and do nothing about displaying it.

Should this be taken into account in defining a preferred performance
aggregation method ? Maybe another discussion thread is needed for that ?

Any opinion ?

Kind regards,

...Louis
