[rrd-users] Re: Need Help with GPRINT

[Watkins, K (Kobe)]

Hi Amir,

I think you're after something like the following: 

...
DEF:myspeed=db1.rrd:speed:AVERAGE
HRULE:80#FF0000:"Overloaded\n"
AREA:myspeed#B9B9FF:"CPU Load"
GPRINT:myspeed:LAST:"    Current\: %3.0lf %%"
GPRINT:myspeed:AVERAGE:"    Average\: %3.0lf %%"
GPRINT:myspeed:MIN:"    Min\: %3.0lf %%"
GPRINT:myspeed:MAX:"    Max\: %3.0lf %%"
...

Cheers,
Kobe

Subject: [rrd-users] Need Help with GPRINT

 Hi, Im quite new to rrdtool, and would be very grateful if you could
help me.  
  
  I have created a graph that displays the CPU load from a server for a
specific period.
  
  I have no problem creating the chart itself.  But I also want to
print the max value (also min and average) of CPU load for that period
at the bottom of graph, like the examples in the gallery.  I have
looked at the sample code and I think ive followed the right  path.  But
I get the error "ERROR: bad format for GPRINT in  '.2lf'" when I try to
run the batch file (I run the command in batch  file in windows).
  
  here is my code
  ---------------------
  rrdtool graph graphs/graph1-1.png --start N-60s --end N -S 1
       --vertical-label 'percentage' -u 100 -l 0 -w 600 -h 150 
      --title "CPU load in the past minute"
DEF:myspeed=db1.rrd:speed:AVERAGE
      VDEF:maxspeed=myspeed,MAXIMUM AREA:myspeed#B9B9FF:"CPU
      load\n" HRULE:80#FF0000:"overloaded\n" GPRINT:maxspeed:"%6.2lf"
  ------------------------
  
  i looked at the other codes and it seems im the only one having this
problem.
  
  Any help would be greatly appreciated
