[rrd-users] Re: Division Bug with RRDTool

[Rodrigo Santos]

Hi Serge,

he forgives but I do not have much knowledge to write scripts in rrdtool
(rrdcreate, rrdupdate), but am sending it my .rrd archives and Makefile
script so that you he can try to help me...

Rrdgraph will be in this format:

/usr/local/bin/rrdtool graph  totals.png
	--interlaced
	--imgformat "PNG"
	--width 640
	--height 150
	-v 'megabits/sec'
	-t ''script': I/O by Network (Mb/s)'
	-s $(/usr/bin/perl -e '$when = time - 24*60*60; if (0 == 923671800 ||
923671800 > $when) { print "923671800" } else { print $when } ')
