I am using drraw with rrdtool-1.0 to create these graphs. I am graphing
router "reliability" which has a max of 255, and want to make the top of the
y-axis "255" like this:
255 --------------------------------------
| |
200 | |
| |
| |
| |
| |
100 | |
| |
| |
| |
| |
0 --------------------------------------
I don't actually care about what else is in the y-axis, I just really want
that 255 at the top and the 0 at the bottom.
I have tried this:
rrdtool graph - \
--start=end-86400 \
--lower-limit=0 \
--title=Reliability Max 255 \
--vertical-label=Reliability Score \
--upper-limit=255 \
--imgformat=PNG \
--width=750 \
--base=1000 \
--height=180 \
--rigid \
--alt-y-grid \
--interlaced \
DEF:a=/data1/mrtg//CA/ssa-pitts-ca-w8cf01_fa0-24_25_reliab.rrd:ds0:AVERAGE
\
AREA:a#008080:Reliability \
GPRINT:a:MIN:Min\: %8.2lf%s \
GPRINT:a:AVERAGE:Avg\: %8.2lf%s \
GPRINT:a:MAX:Max\: %8.2lf%s \
GPRINT:a:LAST:Last\: %8.2lf%s
Which gives me a graph like this:
--------------------------------------
| |
200 | |
| |
| |
| |
| |
100 | |
| |
| |
| |
| |
0 --------------------------------------
This:
rrdtool graph - \
--start=end-86400 \
--lower-limit=0 \
--title=Reliability Max 255 \
--vertical-label=Reliability Score \
--upper-limit=255 \
--imgformat=PNG \
--width=750 \
--base=1000 \
--height=180 \
--rigid \
--alt-y-mrtg \
--interlaced \
DEF:a=/data1/mrtg//CA/ssa-pitts-ca-w8cf01_fa0-24_25_reliab.rrd:ds0:AVERAGE
\
AREA:a#008080:Reliability \
GPRINT:a:MIN:Min\: %8.2lf%s \
GPRINT:a:AVERAGE:Avg\: %8.2lf%s \
GPRINT:a:MAX:Max\: %8.2lf%s \
GPRINT:a:LAST:Last\: %8.2lf%s
Gives me this:
Inf --------------------------------------
| |
| |
Inf | |
| |
| |
Inf | |
| |
| |
Inf | |
| |
| |
Inf --------------------------------------
Which is almost right, except I want actual numbers there not "Inf". I have
no idea what the Inf is or how to fix it.
Any way to get what I want here?
