Hi Charles,
didn't you get the mail I sent you friday ? Here is it again:

!To: Charles Jones <address snipped>

!The hobbitgraph code currently cannot handle the combination of multiple
!hosts and multiple files for one host. So when you define a multi-host
!graph, you must use an FNPATTERN which matches a single file.
!
!I haven't figured out a sensible way of presenting multiple graphs for
!multiple hosts in one image - hence this restriction. If you have any
!ideas on how this can be done, let me know. The images get awfully
!crowded very quickly, and difficult to interpret.

!Regards,
!Henrik

I'm trying to make multi-host graphs out of the following rrd's:
[hobbit at mon rrd]$ find . -name processes\* |egrep 'web-12|web-13'
./web-12/processes.Apache_app1.rrd
./web-12/processes.Apache_main.rrd
./web-12/processes.Apache_app2.rrd
./web-12/processes.Apache_app4.rrd
./web-12/processes.Apache_app3.rrd
./web-12/processes.Apache_app3.rrd
./web-13/processes.Apache_app1.rrd
./web-13/processes.Apache_main.rrd
./web-13/processes.Apache_app2.rrd
./web-13/processes.Apache_app4.rrd
./web-13/processes.Apache_app3.rrd
./web-13/processes.Apache_app3.rrd
The rrds are simple process counts with "count" as the DS:
[hobbit at mon rrd]$ rrdtool dump ./web-12/processes.Apache_app1.rrd |grep name
<name> count </name>
Here is my hobbitgraph.cfg definition:
[processes-multi]
FNPATTERN processes.(.+).rrd
TITLE Multi-host Process counts
YAXIS #
DEF:cnt at RRDIDX@=@RRDFN@:count:AVERAGE
-l 0 -A
LINE2:cnt at RRDIDX@#@COLOR@:@RRDPARAM@
GPRINT:cnt at RRDIDX@:LAST: \: %10.1lf (cur)
GPRINT:cnt at RRDIDX@:MAX: \: %10.1lf (max)
GPRINT:cnt at RRDIDX@:MIN: \: %10.1lf (min)
GPRINT:cnt at RRDIDX@:AVERAGE: \: %10.1lf (avg)\n
This looks to me like it should work, at least assuming that there are
the same number of .rrd per host (there are), but I'm getting a broken
graph image when I try to do a metrics report for multi-host processes
counts. I have found that if I do a metrics report on a SINGLE host,
the graph displays properly. Any idea what could be wrong?
