Multi-host process graphs

[Charles Jones <jonescr (at) cisco.com>]

Has anyone had any luck in creating multi-hosts process graphs? Here are 
the steps I have done so far in trying to get it to work. If anyone sees 
what I am doing wrong, any advice would be appreciated.

1. Created a multi definition in hobbitgraphs.cfg
[processes-multi]
       FNPATTERN processes.(.+).rrd
       TITLE Multi-host Process counts
       YAXIS #
       DEF:cnt (at) RRDIDX@= (at) RRDFN@:count:AVERAGE
       -l 0 -A
       LINE2:cnt (at) RRDIDX@# (at) 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

2. Edited hobbit/server/web/hostgraphs_form and added the extra option 
for process counts:
<option value="processes">Process counts</option>

3. Made sure that the process rrds are there (I know they are anyway 
because I see the graphs in trends):
$ ls data/rrd/prod-web-1/processes.*
data/rrd/prod-web-1/processes.Apache_portal.rrd    
data/rrd/prod-web-1/processes.Apache_tomcat.rrd
data/rrd/prod-web-1/processes.Apache_research.rrd  
data/rrd/prod-web-1/processes.Apache_main.rrd
data/rrd/prod-web-1/processes.Apache_proxy.rrd

Now when I go to the Metrics Report, and select prod-web-2 and 
prod-web2, along with Process counts. I get a missing graph, so 
something isn't working right.  The same hosts work fine with other 
multi-host graphs like la1, cpu, etc.

any ideas?
