[rrd-users] Re: graphing problem.

[Warnes, Jason SktnHR]

Like Laurie mentioned in a previous post, the 'm' in 1000m stands for milli
with is 1/1000th of a full unit.  So 1000m = 1.

What you may want to do is add:
	"--units-exponent=1" for forcing the graph to use full units
	"--upper-limit=2" for forcing the upper Y-axis boundary
	"--rigid" to make sure RRDTool doesn't auto-scale it

Subject: [rrd-users] graphing problem.




  I used to fill my rrd with small values, range from 0.00 to 2.00 
(yes, system load ;)). But, when values are small, like 0.1 - 1.00, rdd 
graphs it completely wrong, there are values from 0 to 1000m (?) on Y axis.
Why?

<source>
$_=`uptime`; chomp;
s/[a-zA-Z:\ ]+//g;
@uptime=split(/,/);

RRDs::update($db_dir.$db_file,"N:$uptime[3]:$uptime[4]:$uptime[5]");

RRDs::graph($png_dir.$png_file,
            "-v System load","-w600","-h150","-y 0.2:5","-b1000",
            "-aPNG","-t HADES - system load",
            "HRULE:1.5#FF0000:System overload.\\n",
            "COMMENT:\\n",
            "DEF:sload1=".$db_dir.$db_file.":sysload1:AVERAGE",
            "LINE1:sload1#c60f1f: 1 min.\\n",
            "DEF:sload2=".$db_dir.$db_file.":sysload5:AVERAGE",
            "LINE1:sload2#373df2: 5 min.\\n",
            "DEF:sload3=".$db_dir.$db_file.":sysload15:AVERAGE",
            "LINE1:sload3#000000: 15 min.\\n",
            "COMMENT:\\n");
