- the result of a function over a complete time series
- of data (DEF or CDEF) such as the maximum seen, and when.
-
-2001/03/10 Jake Brutlag <jakeb@corp.webtv.net>
- Support for COMPUTE data sources (CDEF data sources). Removes the RPN
- parser and calculator from rrd_graph and puts then in a new file,
- rrd_rpncalc.c. Changes to core files rrd_create and rrd_update. Some
- clean-up of aberrant behavior stuff, including a bug fix.
- Documentation update (rrdcreate.pod, rrdupdate.pod). Change xml format.
-
-2001/03/07 Tobias Oetiker <oetiker@ee.ethz.ch>
- Integrated complete rewrite
- of rrdgraph documentation by Alex van den Bogaerdt
- <alex@ergens.op.Het.Net>. This also contains info on his planned
- changes to the rrdgraph module
-
-2001/03/02 Tobias Oetiker <oetiker@ee.ethz.ch>
- Added Aberrant Patch from Jake Brutlag <jakeb@microsoft.com>
- From now one, new rrd files use version tag 0002. They can
- NOT be read by the old 1.0.x rrdtools.
-
- Jake:
- Aberrant Behavior Detection support. A brief overview added to
- rrdtool.pod. Major updates to rrd_update.c, rrd_create.c. Minor update to
- other core files. Updated documentation: rrdcreate.pod, rrdgraph.pod,
- rrdtune.pod. This is backwards compatible (i.e. new tool can read and will
- leave the binary header unchanged for old files).
