Summary: Hyperthreaded CPU count is wrong
Initial Comment:
Ganglia reports the 4 virtual processors as the number
of CPUs on
a dual physical CPU machine. This gives the false
impression of the
system being half loaded when in fact it's fully loaded.
Since hyperthreading is new and people will most likely
want different
behaviours, perhaps the best solution is to offer a
configuration option
to count virtual or physical CPUs when reporting such info.
By the way, with the latest RedHat kernel
(2.4.18-19.7.x), you can
correctly determine the number of physical CPUs (via
command line)
by:
$ grep "Physical processor" /proc/cpuinfo | uniq | wc -l
2
