Oops, my bad, I'd been using a patched version of cpu_num_func for a while
and almost forgot that the source wasn't yet fixed.
I'd updated the patch and rebuilt it with the last SVN revision and tested it
in my Windows XP SP2 Home laptop (only 1 CPU though) but haven't had the
opportunity to test it in any multi core/multi CPU windows environment.
Attached the patch for comments, and in the following address a binary gmond
built with it to simplify testing (using --enable-static-build) :
http://www.sajinet.com.pe/ganglia/gmond-3.1.0-bin.zip
in order to test it do the following :
1) unzip (using windows explorer - extract all) the contents in c:\progra~1
2) change c:\progra~1\ganglia\gmond.conf to match your environment for a
collector (if not change 192.168.0.11 with your own IP so it collects to
itself)
3) stop any other cygwin related applications (including services)
4) go to c:\progra~1\ganglia and run :
gmond.exe -c gmond.conf
a telnet to TCP 8649 in the collector should print the cpu_num metric with the
right value.
