Hello, I''ve tried to get the CPUFreq plugin of collectd running in dom0. But I mentioned that it isn''t so easy to get a file in sysfs on the rigth place. I know that the value has to come from hypervisor and I''ve seen the code in xenpm. The only value I need is "/sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq" which would create cpufreq.c. Can anyone
