Possible to sum rrd into one graph ?
list Thomas Seglard
Hello, In Munin, its possible to sum several rrd into one graph (ie : to display the total bandwidth used by all your media servers). Thus, I'm asking if it's possible to do this in XYmon too ? I saw the < Metrics reports > but you can't sum graphs... Regards, Thomas SEGLARD

Yes. I posted my example on the wikibook in pretty good detail I think.

Hi Josh, Thanks for your answer. I'm afraid but I only find this on the wikibook : http://en.wikibooks.org/wiki/System_Monitoring_with_Xymon/Other_Docs/FAQ#Is_there_a_way_within_Hobbit_of_creating_a_graph_with_data_from_multiple_RRD_files_.3F There is nothing explained and the « ddraw » tool seems a little bit tricky to setup and use. Hence, I think I don't find your example. Please, could you post a link or give some clues on this subject ? Thanks. Thomas

Take a look at the man page for rrdgraph_data. That describes how to use
CDEF:
CDEF
CDEF:vname=RPN expression
This command creates a new set of data points (in memory only, not
in
the RRD file) out of one or more other data series.
After using DEF to define the variables being pulled from the various RRDs,
you should be able to combine them with a math expression. You would then
use the CDEF vname in the graph LINE, AREA, etc.

Hello, yes, you're right. But, my mistake, this is only part of answer and I don't exactly write what I wanted to know. What I want is a way to sum the RRDs from different servers and corresponding to the graph definition « ifstat ». The main problem is that the RRDs are not in the same place/directory and thus I have no way to tell rrdtool where to get these RRDs. This is the main problem and why I required some help J I could do some scrtipt which sync on a regular basis these RRDs into one server directory. It's not very elegant (but I think this will work !). In a future release, maybe it will be possible to use the Metrics reports to do all the maths we want with different RRDs ? ;) Nobody uses Xymon to graph the sum of network bandwidth from different sources (firewall, lb, media servers, web servers, etc...) into one graph ??

Easy, make a subdirectory like graph1 and in that subdirectory add symlinks to the different rrd files. You can give the symlink an other name like graph/vmstat-server1.rrd -> server1/vmstat.rrd In the graph definition, you can match all vmstat-* files and voila, you can make the sum of what you want: [vmstat-avm-total] FNPATTERN vmstat-(.+).rrd TITLE Accessed Virtual Memory YAXIS Size kB -b 1024 DEF:avm at RRDIDX@=@RRDFN@:mem_avm:AVERAGE CDEF:sw at RRDIDX@=avm at RRDIDX@,4048,* LINE1:sw at RRDIDX@#@COLOR@:@RRDPARAM@:STACK GPRINT:sw at RRDIDX@:LAST:AVM \: %5.1lf%s (cur) GPRINT:sw at RRDIDX@:MAX: \: %5.1lf%s (max) GPRINT:sw at RRDIDX@:MIN: \: %5.1lf%s (min) GPRINT:sw at RRDIDX@:AVERAGE: \: %5.1lf%s (avg)\n I do this for adding CPU load on a pSeries with lpars so I can make the sum of all physical CPU usage.

If you're using DEFs like this:
[la]
TITLE CPU Load
YAXIS Load
DEF:avg=la.rrd:la:AVERAGE
CDEF:la=avg,100,/
you can definitely use a pathname for the RRD. I do exactly that with some
performance graphs where I can't use xymon:
DEF:server1avg=/var/lib/perfmon/server1/loadavg.rrd
DEF:server2avg=/var/lib/perfmon/server2/loadavg.rrd
I don't know if the same is true of the FNPATTERN style of setting DEFs.
Of course, if your RRD are on different physical machines, that's a bit
harder... :)

Hi, I failed to achieve this. Actually, it doesn't display any graph at all. Hence, I send this new message. What is the best solution to be able to make ONE graph displaying the sum of all bandwidth consumed by my servers delivering media content ? I done this very simply with Munin so I'm very disapointed that its impossible to make it as simple with Xymon. Thanks for help.
