Steven:
Glad that you got things sorted out.
Someone should file a bug on this and somebody from the Gweb team should
take a look at the issue.
Thanks all,
Bernard

Peter,
I've attached the xml.
The rrds are in /var/db/ganglia/rrds

Aha scl-rsa3 in lower-case!
So
cd /var/db/ganglia/rrds/Shepherd2
ln -s scl-rsa3 SCL-RSA3
And I have metrics in graphs :))
I know that's not pretty but it proves the point.
Thanks you so much for walking me through this.
It occurs to me that a DNS lookup would return the server name in
lower-case but the in XML the original server uses it's given name which we
capitalize here.

Subject: Re: [Ganglia-general] Ganglia for Windows
Can you send the output of an XML query to gmond? You can use telnet to
connect to the tcp_accept_channel on the gmond machine:
telnet localhost 8649
It does sound like gmetad is successfully picking up the data and updating
the RRDs. It does seem likely that there is an issue with the way that the
web-UI is indexing and referencing the RRDs. What are the directory and
file names under /var/lib/ganglia/rrds?
ls /var/lib/ganglia/rrds/cluster
ls /var/ib/ganglia/rrds/cluster/SCL-RSA3
I am afraid I don't know much about how the UI deals with the data, but
there must be something basic about how the data is being stored that is
somehow different between the BSD and windows machines.
Since Ganglia stores the data under directories keyed by hostname, I
suspect that there could be some issue with the hostname? Perhaps the new
Ganglia UI is case sensitive and doesn't like the capitalized hostnames
exported from Windows? I have mostly used the old UI and there haven't been
issues with monitoring Windows servers - it is possible that there are
differences in the way hostnames are treated in the new code.

My setup is:
FreeBSD 9 with gmetad 3.3.0, gmond 3.3.0 and web 3.3.1
I can see metrics for this machine (which is a PC I'm using for the

FreeBSD 8.1 with 3.1.7
I can see metrics for this machine (I installed 3.1.7 on a it is the
latest port for FreeBSD - not really part of the trial)
Windows Server 2003 with Host sflow v 1.20
Alas, most of our servers run Windows 2003 so when someone on the list
drew my attention to sflow, I jumped at it.
I have looked at the rrds for the win server and the mod times are
changing. Rrdtool dump shows that the contents are changing and 'rrdtool
dump pkts_in.rrd | grep 'v' | grep -v NaN | wc -l' shows that the number
of values that are not NaN is going down, all of which suggests to me that
the data is being received, stored and aggregated.
Is it possible I'm missing something from gweb2? I haven't been able to
find a canonical list of requirements for it so it's entirely possible I've
missed something.
