Bug Fixes
parse numbers up to 40 characters long ..
fix install rules for Python and Lua
include missing VERSION and LICENSE file
unlink before rename in rrd_create when running on WIN32
v1.5.0
9 years ago
New Features
automatic x-axis labels that work from 1s to 30y on a single chart
librados integration
new datasource types: DCOUNTER and DDERIVE (they work the same as the original DS, except that they can deal with floatingpoint numbers).
compile without graphics libraries: ./configure --disable-rrd_graph
updated windows port (see WIN32-BUILD-TIPS.txt)
single step RRAs for MIN,MAX,LAST are generated virtually from an AVERAGE RRA
ignore updates in the past with rrdtool update --skip-past-updates
ignore a LINE when scaling a chart using the skipscale option
detect 32bit timeoverflows
massive performance boost for charts with more than 100 DEF line by switching form a linear search to a HASH when searching for data
improved cross compilation support
.Net bindings
allow rrdtool graph to silently skip non-existing source files using the --use-nan-for-all-missing-data option
restore from a pipe (rrdtool restore - y.rrd)
in rrdtool create, row count and step can be defined in absolute time
all new "create on steroids" can pull both data and configuration from existing rrd files
use rrdtool graph to chart arbitrary data via a callback function for data fetching support is integrated in the perl bindings.
re-written parser for rrdtool graph commands. It now follows a simple key value pattern, compatible with the previous syntax.
MEDIAN op for CDEF expressions
DEPTH,INDEX,COPY,ROL ops for CDEF (as seen in PostScript)
gradient AREA backgrounds
no more locale magic while reading numeric data.
