rrd graph issues

Hi all, I've been working with my graph for awhile to try to figure out why
I get values greater than 100% for my graph, which isn't possible. Here is
my graph definition
rrdtool.graph('cpu.png',
'--start','now-3600',
'--end','now',
'--upper-limit','100',
'--lower-limit', '0',
'DEF:uj=cpu.rrd:user:AVERAGE', #define number of jiffies
'DEF:nj=cpu.rrd:nice:AVERAGE',#which are the number of ticks
'DEF:sj=cpu.rrd:sys:AVERAGE',
'DEF:ij=cpu.rrd:idle:AVERAGE',
'CDEF:tj=uj,nj,+,sj,+,ij,+',
'CDEF:bo=uj,UN,0,uj,IF,0,GT,UNKN,INF,IF',
'AREA:bo#DDDDDD:',
'CDEF:usr=100,uj,*,tj,/',
'CDEF:nic=100,nj,*,tj,/',
'CDEF:sys=100,sj,*,tj,/',
'CDEF:idl=100,ij,*,tj,/',
'CDEF:tot=100,tj,*,tj,/',
'AREA:nic#0040A2:Nice',
'VDEF:maxN=nic,MAXIMUM',
'VDEF:minN=nic,MINIMUM',
'VDEF:avgN=nic,AVERAGE',
'GPRINT:maxN: Max %6.2lf%%',
'GPRINT:minN: Min %6.2lf%%',
'GPRINT:avgN: Avg %6.2lf%%\l',
'AREA:sys#90C5CC:System:STACK',
'LINE2:1#70A5AC::STACK',
'VDEF:maxS=sys,MAXIMUM',
'VDEF:minS=sys,MINIMUM',
'VDEF:avgS=sys,AVERAGE',
'GPRINT:maxS:Max %6.2lf%%',
'GPRINT:minS: Min %6.2lf%%',
'GPRINT:avgS: Avg %6.2lf%%\l',
'AREA:usr#B0E5EC:User:STACK',
'LINE2:1#90C5CC::STACK',
'VDEF:maxU=usr,MAXIMUM',
'VDEF:minU=usr,MINIMUM',
'VDEF:avgU=usr,AVERAGE',
'GPRINT:maxU: Max %6.2lf%%',
'GPRINT:minU: Min %6.2lf%%',
'GPRINT:avgU: Avg %6.2lf%%\l',
'AREA:idl#0000ff:Idle:STACK',
'VDEF:maxI=idl,MAXIMUM',
'VDEF:minI=idl,MINIMUM',
'VDEF:avgI=idl,AVERAGE',
'GPRINT:maxI: Max %6.2lf%%',
'GPRINT:minI: Min %6.2lf%%',
'GPRINT:avgI: Avg %6.2lf%%\l',
'--vertical-label','Ticks',
'--title','Hourly CPU Usage',
'COMMENT:' + cur_date + '')
As you can tell I have 4 data sources being graphed, and I contvert these
DERIVE DST into percentages so the maximum percentage is 100%, and I'm
getting a graph that graph above 100%. Also I've put a limit on the graph to
try to cope with this issue, Max 100 Min 0 and it starts off good but once
it updates then the limit doesn't apply anymore. I'm not sure what's going
on here and why, when the values aren't greated than 100 (they're about 98
or 99). Does it have anything to do with the STACK command? Please any help
would be appreciated!

OMG!
I've tried to understand you... I think I have...

You need to use the GPRINT function to print the MAX and MIN RRAs...
Something like this at you rrdtool graph command:

"GPRINT:%ds%:MIN:Minimum\:%6.0lf\l"
"GPRINT:%ds%:MAX:Maximum\:%6.0lf\l"

Overwrite "%ds%" with the desired data source

So what I've gathered from working with this, is once I removed the
stack and turned the line into an area it all seem to work out.
Therefore I assume, and please correct me if I'm wrong, but when you use
STACK the width of the line value is added so that in may case where it
should of displayed 99% instead it displayed a value above 100%, is
there a way to get around this so that I can still create the beautiful
graph I want but not have the STACK affect my final displayed values?

If you use STACK then whatever you are drawing is stacked on top of
the last plot - ie the last plot is used as the baseline and your
values are added.

If you don't use stack, then the values are plotted from 0 as a baseline.

I'm not 100% sure what you are trying to achieve - I think you are
trying to draw an area for Nice, then a line 1% above it, then an
area above that for Sys, another line 1% above that, and so on with
User and Idle. Since you are drawing three lines, each value 1
stacked on top of Nice, Sys, and User, then the total will always be
103%.

Why not draw a line at value 0 ?

If that doesn't work, then you could draw the stacked areas, then go
back and draw lines at Nice, Nice+Sys, and Nice+Sys+User.
