This module shows the current CPU frequency as set by the cpufreq kernel module.
You need to have
CONFIG_CPU_FREQ and (optionally)
enabled in your kernel.
This module tries to read from one of two possible locations. On
initialization, it tries to read the
time_in_state files provided by
cpufreq_stats. If this file does not exist, or doesn't contain valid data, it
falls back to using the more inaccurate
scaling_cur_freq file (which only
represents the current CPU frequency, and doesn't account for any state
changes which happen between updates).
It produces one chart with multiple lines (one line per core).
If no configuration is given, module will search for cpufreq files in
Directory is also prefixed with
NETDATA_HOST_PREFIX if specified.
