I'm running Zenoss 3.2.0 on Ubuntu 10.04 and am attempting to use the fping zenpack.  I installed the ZenPacks.BlakeDrager.fping-1.0-py2.6.egg package via the command line with debug on and observed no errors.. so all indications are that it installed properly, however the graphs aren't generating properly.

Under the config for the datasource, the test results come back like I would expect:

PING OK|xmt=3 rcv=3 loss=0 min=23.0 avg=27.7 max=36.9

I get a value and a line for Pings Sent, but all other values are showing up as nan.  Looking in the /usr/local/zenoss/zenoss/perf/Devices/1.2.3.4 folder, I see an fping_xmt.rrd file, but no others.  Watching the zencommand.log after enabling debug, I can see a series of entries about fping, culminating with the following:

2011-09-20 16:00:32,344 DEBUG zen.zencommand: The result of "/usr/bin/fping -c 3 -sq  1.2.3.4 2>&1 | /bin/sed 's/\([0-9]*\)\/\([0-9]*\)\/\([0-9]\)%/xmt=\1 rcv=\2 loss=\3/;s/\([0-9]*.[0-9]*\)\/\([0-9].*\)\/\([0-9].*\)/min=\1 avg=\2 max=\3/' | /bin/sed -r '/targets/,/real time/d;s/[0-9]*.[0-9]*.[0-9]*.[0-9]* : xmt\/rcv\/%loss = /PING OK|/;s/, min\/avg\/max = / /'" was "'PING OK|xmt=3 rcv=3 loss=0 min=79.7 avg=112 max=169\n\n\n'"

2011-09-20 16:00:32,346 DEBUG zen.zencommand: Storing xmt = 3.0 into Devices/1.2.3.4/fping_xmt

There are no errors or other indications that any of the other values are even being processed.

Any ideas on why this isn't working?  I've read multiple posts on issues with fping graphing, but none of them seem to fit this scenario exactly.  The closest I found was resolved by starting over with a clean install, but I've been able to reproduce this on a VM with a brand new installation of Ubuntu.

Thanks
