Steve,

It is pretty easy!  Just follow the instructions.   But if you do not want
to read the instrucitons and do the easy way here is your answer. (Joking
around)

Go to
http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/tutorial/rrdtutorial.html
and read the tutorial :)  or read on.

Get the hint? :)

rrdtool graph seconds1.gif                       \
      --start 920804700 --end 920806200             \
      --height 200                                  \
      --upper-limit 1.05 --lower-limit 0.95 --rigid \
      DEF:seconds=seconds1.rrd:seconds:AVERAGE      \
      CDEF:unknown=seconds,UN                       \
      LINE2:seconds#0000FF                          \
      AREA:unknown#FF0000
   

Notice in here where we define the rrd?  specifically
DEF:seconds=seconds1.rrd:seconds:AVERAGE?  well take a gander at what you
need to change.  Yes thats right. The DEF.

So for your answer in an easy to read format:
rrdtool graph seconds1and2.gif                       \
      --start 920804700 --end 920806200             \
      --height 200                                  \
      --upper-limit 1.05 --lower-limit 0.95 --rigid \
      DEF:seconds=seconds1.rrd:seconds:AVERAGE      \
      DEF:seconds2=seconds2.rrd:seconds:AVERAGE      \
      LINE2:seconds#0000FF                          \
      LINE2:seconds2#FF00FF                          \

Yes there are probably some syntas errors but you should (hopefully) get the
idea.

Have a great day/night

David

Hi,

Does anyone have a sample command line to graph using RRDTOOL two rrd files
created from MRTG ping probe configs?

The idea is I want to be able to compare the two response times (in seperate
.RRD files) on the same graph, and also appy the same method for other data.

Thanks

Steve
