Object
column
r/w
Unsigned32
The coefficient used by the low-pass filter procedure
to specify the relative weights applied to
(a) the increase in the rate-count value during the most
recent agingInterval and
(b) the previous low-pass filtered rate.
The former is assigned a weight of 1 and the latter a
weight of (lpCoef-1).
The value is interpreted as 2 raised to the power
specified by this attribute.
The default value is 6, giving a low-pass coefficient
of 2**6, or 64.
