a swiss consultancy has implemented a native windows gmond, and the
binaries
are in the public domain and free. Follow the trail here:

I believe they are also offering ganglia consulting, support, and

unfortunately the problem lies with cygwin rather than Ganglia.
The windows agent is essentially the same as the Linux one

Markus,
your envionment certainly sounds like it is under control,
but in mine, the engineered Linux build has packages that in some
instances are really quite old. Old enough for the Ganglia build to
barf.
In some cases a fix would have been easy because the package was not
there at
all. And
Fair enough,
although I did not realise you were talking about apr.
I was talking about autoconf, freetype, libart, rrdtool etc,
and all of those are installed in /opt/ganglia.

out of interest, when you say you use the gmetric interface, are
you still doing XDR binary encoding for the core metrics, or are
you having all the metrics as sets of strings (ala gmetric)?

thanks for the reply. It would make sense that perhaps the code is
a legacy of before when collection_groups were implemented (aside:

as an example, run nc localhost 8651 on your ganglia server.
That is the grid level raw data that could be used for snapshot
processing.
If you netcatted directly to a cluster member (or headnode if you
unicast), then
that provides current values for the cluster.
So even though a C API
Nah, don't worry.
If no firewalls are present, UDP spoofing is trivial anyway,
so you are not making the UDP gmond comms materially less secure.

Miguel,
you may want to consider parsing the XML for all your clusters
on your server (by connecting to localhost oprt 8651).
This perl for example prints hosts that are down:
#!/usr/bin/perl
open (FD, nc localhost 8651 |) or die
All,
the attached patch file can be applied to the php web
code to enable you to click on the smaller graphs in
the cluster and host views, and then get a bigger graph.
It is based on the 3.0.3 release, but you prpbably
patch the 3.0.2 release too, as little has changed.

Hi Martin,
I would be keen on a new tarball also.
Will this tarball include Matt's fix to the XML truncation problem?
(I think it is in CVS, so I assume yes).

Although looking at the fairly scary apr code, it
rather looks like the function has different semantics
between wnidows and UNIX - windows supporting blocking
IO with a timeout, but the UNIX case kind of looks like
blocking implies no timeout.

But I still think you need the else to set xmldata-old to 0.

yes, quite right - it would be a hard loop until EAGAIN went away.
As I do 5 second polling rather than 20, I would prefer not to put
a simple sleep in.
One could always have a counter timeout, or a timeout after
(say) 1-2 seconds of looping. In fact I am nervous now, so I think
