I'm trying move from mrtg to rrdtool, to get more control of the graphs
This is my 12 hours graf (php-code) for data collected from a cisco router:
$rrd12 = "rrdtool graph ppp12.png --title=\"PPP Trafik over 12 timer (MAX)\"".
" --start end-12hours ".
" --x-grid MINUTE:10:HOUR:1:HOUR:2:0:%R ".
" --imgformat PNG ".
" --width 600 --height 150 ".
" --vertical-label \"Bytes per second\" ".
" DEF:in=ppp.rrd:ds0:AVERAGE ".
" LINE2:in#00FF00:\"In traffic \"".
" GPRINT:in:MAX:\"Max\\: %7.0lf bytes/s\"".
" GPRINT:in:MIN:\"Min\\: %7.0lf bytes/s\"".
" GPRINT:in:AVERAGE:\"Avg\\: %7.0lf bytes/s\"".
" GPRINT:in:LAST:\"Last\\: %7.0lf bytes/s\\l\"".
" DEF:out=ppp.rrd:ds1:AVERAGE ".
" LINE1:out#0000FF:\"Out trafffic\"".
" GPRINT:out:MAX:\"Max\\: %7.0lf bytes/s\"".
" GPRINT:out:MIN:\"Min\\: %7.0lf bytes/s\"".
" GPRINT:out:AVERAGE:\"Avg\\: %7.0lf bytes/s\"".
" GPRINT:out:LAST:\"Last\\: %7.0lf bytes/s\"";
exec("rm -f ppp12.png", $returntxt, $returnflag);
Some questions
1. I'm using GPRINT to show max, min, average and last data.
How can I make a percentage of total calculation to show for each like in MRTG ?
2. rrdtool is graphing the data in kBytes/s.
How can I make i draw the lines and scale it in kbits/s ?
3. What will happen to my data (generated my mrtg)
if I want to graph the peaks (in day, week, month and year graphs) instead of
the average?
and is it enough to write: DEF:out=ethernet.rrd:ds1:MAX ?
