Tasks

Monitoring CPU frequency

Simplest way is to use an exec input:

[[inputs.exec]]
  commands = ['bash -c "cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq|/bin/awk \'{freq += \$1; n++} END{printf(\"%f\", freq/n/1000); }\'"']
  name_override = "cpu_freq"
  data_format = "value"
  data_type = "float"
