4 * change header parameters of an rrd

8 * Revision 1.6 2004/05/26 22:11:12 oetiker
9 * reduce compiler warnings. Many small fixes. -- Mike Slifcak <slif@bellsouth.net>
11 * Revision 1.5 2002/02/01 20:34:49 oetiker
12 * fixed version number and date/time
14 * Revision 1.4 2001/08/22 22:29:07 jake
15 * Contents of this patch:
16 * (1) Adds/revises documentation for rrd tune in rrd_tool.c and pod files.
17 * (2) Moves some initialization code from rrd_create.c to rrd_hw.c.
18 * (3) Adds another pass to smoothing for SEASONAL and DEVSEASONAL RRAs.
19 * This pass computes the coefficients as deviations from an average; the
20 * average is added the baseline coefficient of HWPREDICT. Statistical texts
21 * suggest this to preserve algorithm stability. It will not invalidate
22 * RRD files created and smoothed with the old code.
23 * (4) Adds the aberrant-reset flag to rrd tune. This operation, which is
24 * specified for a single data source, causes the holt-winters algorithm to
25 * forget everthing it has learned and start over.
26 * (5) Fixes a few out-of-date code comments.
28 * Revision 1.3 2001/03/07 21:21:54 oetiker
29 * complete rewrite of rrdgraph documentation. This also includs info
30 * on upcomming/planned changes to the rrdgraph interface and functionality
31 * -- Alex van den Bogaerdt <alex@slot.hollandcasino.nl>
33 * Revision 1.2 2001/03/04 13:01:55 oetiker
34 * Aberrant Behavior Detection support. A brief overview added to rrdtool.pod.
35 * Major updates to rrd_update.c, rrd_create.c. Minor update to other core files.
36 * This is backwards compatible! But new files using the Aberrant stuff are not readable
37 * by old rrdtool versions. See http://cricket.sourceforge.net/aberrant/rrd_hw.htm
38 * -- Jake Brutlag <jakeb@corp.webtv.net>
