THIS MODULE IS OBSOLETE. USE THE PROC PLUGIN - IT IS MORE EFFICIENT
This module shows the current CPU frequency as set by the cpufreq kernel module.
Requirement:
You need to have CONFIG_CPU_FREQ and (optionally) CONFIG_CPU_FREQ_STAT
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).
Sample:
sys_dir: "/sys/devices"If no configuration is given, module will search for cpufreq files in /sys/devices directory.
Directory is also prefixed with NETDATA_HOST_PREFIX if specified.
