Hey all,
I have a quick question. Heres the senerio:
Note: Im graphing how many pages printed per/half hour from HP
printers.
I create an rrd (filename 1.rrd).
I use perl's " use RRDs; " command to a create the graph.
Why do I get different values when I make my start and end times
over aprox 13days?
-> If I choose to graph 5 days the max value would be 140 pages.
-> If I choose to graph 20 days the max value would change to ~70
pages.
Why does this happen?
---------------Heres my create and graph script.------------------
$time equals the first time in the file.
RRDs::create("/tmp/1.rrd", "--start", "$time-1", "--step", "1800",
"DS:value:COUNTER:2100:U:U",
"RRA:AVERAGE:0.5:1:35040","RRA:MAX:0.5:1:35040","RRA:MIN:0.5:1:35040");
----------------Heres how I create the graph-----------------------
@options=("-l 0","-s $starttime","-e $endtime",
"-v pages per half hour",
"-cCANVAS#F5FFFA","-cGRID#D2B48C",
"-h $height","-w $width",
"-u 25","-aGIF",
"-t $title $currenttime");
@DEF=();
@PLOT=();
@LEGEND=();
$newstr="DEF:${i}A=$foobar:value:AVERAGE";
push(@DEF,$newstr,
"CDEF:${i}${oida}=${i}A,1800,*",
"LINE2:${i}${oida}$colors{$i}:$oida \: ","COMMENT: \t ",
"COMMENT: $printerdevices{$databasename} - AVG",
"GPRINT:${i}${oida}:AVERAGE:%4.0lf",
"COMMENT:MAX",
"GPRINT:${i}${oida}:MAX:%4.0lf",
"COMMENT:MIN",
"GPRINT:${i}${oida}:MIN:%4.0lf",
"COMMENT:LAST",
"GPRINT:${i}${oida}:LAST:%4.0lf\\n");
push(@LEGEND,
"HRULE:$FIXED#FF0590:Base Line $FIXEDLABEL pages",
"HRULE:-$FIXED#FF0590:",
"HRULE:0#000000:");
$fileOutFinal="/tmp/file.gif";
RRDs::graph(( -w $fileOutFinal)? $fileOutFinal : $fileOutFinal ,
@options,
@DEF,@PLOT,@LEGEND);
