RRDTOOL NEWS ============ Major Changes between 1.0.x and 1.2.x Graphing -------- Logging ------- * In addition to the PNG format, rrdtool can produce output in SVN, EPS and PDF format. Behind the Scenes ----------------- * In order to support Holt-Winters and Calculated Datasources, the rrdtool dataformat has changed. While the new version of rrdtool can read files created with rrdtool 1.0.x. It is not possible to read files created by rrdtool-1.2.x with rrdtool-1.0.x * External libraries are not included with rrdtool anymore. This is in line with todays trend of using shared libraries everywhere. With the exception of the cgi library most things required by rrdtool will be found on every recent system. Configure and Makefiles and accordingly. 2002/03/26 Peter Speck Contribution of an svg output routine for the new gfx graphing part 2002/03/23 Alex van den Bogaerdt Several visible changes made to rrd_graph * Pie chart support workable * Elements that are not used do not take up space on the img * Hack for the missing rotated text (see --vertical-label) * Tiny boxes in front of labels now scale with the text 2002/01/15 Tobias Oetiker The BIG graph update * Replace libgd with libart * Added freetype * Updated zlib and libpng * rrd_gfx.c intrduced as libart wrapper * LINE takes now a float as argument * RRDtool uses truetype for fonts * thanks to libart there is now full alpha transparenc and antialiasing. * the new option --font lets customize the font and size for various graph elements * Updated to -> libtool 1.4.2 automake 2.12 autoconf 2.52 * new --zoom commandline option for zoom ans shrinking ---- Still missing is rotatet text for the yaxis description ---- Still missing is tab support in the text rendere ---- Still missing is autoconf support for a default truetype font 2001/07/26 Alex van den Bogaerdt Added TOTAL to the VDEF functions. 2001/07/19 Alex van den Bogaerdt VDEF support. This is a variable containing one value and a time component. This type of variable can hold 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 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 Integrated complete rewrite of rrdgraph documentation by Alex van den Bogaerdt . This also contains info on his planned changes to the rrdgraph module 2001/03/02 Tobias Oetiker Added Aberrant Patch from Jake Brutlag 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). See http://cricket.sourceforge.net/aberrant/rrd_hw.htm
