Fabian, what kernel version are you running?
/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq should be
applicable if you are running a 2.6 kernel.
I'm only guessing here, but if you do "strings /usr/sbin/gmond", it
looks like gmond checks the following:
/proc/sys/kernel/osrelease
Maybe there's a logic in gmond such that if you are running a Linux
machine with a 2.6 kernel it checks
for /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq. And that'll
get used by the frontend to display cpu_speed.
On one of our hosts, /proc/cpuinfo reports 1800.248 Mhz, while
scaling_max_freq is 2000000.
And Ganglia frontend reports cpu_speed as 2000Mhz.
I'm running gmond v3.0.5.
