[rrd-users] Max Min and Avg RRAs

[Gellatly, Laurie]

Hi,
I'd like to store three values, being the maximum, average and minimum
response times measured. This I'm doing now. I'd then like RRAs that
use consolidation of Maximum, Average and Minimum to correspond to the
DS so that my consolidation is logically:
the maximum of the maximums
the average of the averages and
the minimum of the minimums.
Conceptually, people can understand what is then being recorded.
At present, there appears to be no way to do this within a single
rrd without storing two consolidations extra for each DS.

My only alternative is to have three RRAs. 

Extending the definition of the RRA to read:
RRA: CF[CF2,CF3..CFn]:xff:steps:rows
so you can define your consolidation factor for all or for each DS
would be great. I know that storage is cheap but when you start to
multiply up the number of RRDs that would be involved and then there 
is the processing of the data. 

Havn't looked under the hood to see how difficult this would be 
to implement OR maybe I've missed something obvious and all this
is totally unnecessary. Comments/Suggestions?

TIA.			...Laurie :{)
