[rrd-developers] Understanding HW

[Kiss Gabor (Bitman)]

Dear folks,

I try to study deep details of Holt-Winters related code.

In rrd_crate.c (1.2.15) I found that "seasonal period" and "rows" parameters
of DEVSEASONAL, SEASONAL and FAILURES RRAs are simply ignored.
These values are always overridden by "seasonal period" of HWPREDICT.

See lines like
	current_rra -> row_cnt = period;
in create_hw_contingent_rras().

Is this true or did I miss something?
