Dear Ladies and Gentlmen,

About two years ago if I understand correctly, the Cricket/WebTV people
modified rrdtool to support anomaly detection with a new RRA called
HWPREDICT (Holt Winters time series prediction).

Please would you let me know of

. any experience with that version of rrdtool - does it actually
usefully detect anomalies ?

. if the modifcations are going to be incorporated into rrdtool ?

Thank you,

Yours sincerely.

'...No man is an island, entire of itself; every man is a piece of the
continent, a part of the main. If a clod be washed away by the sea,
Europe is the less, as well as if a promontory were, as well as if a
manor of thy friend's or of thine own were. Any man's death diminishes
me, because I am involved in mankind; and therefore never send to know
for whom the bell tolls; it tolls for thee...'

from Meditation 17, J Donne.
