txcanyon:

Supply the following if possible:

  • Device problem occurs on x86_64 device with Intel i5-4570T cpu/4gb of ram
  • Software versions of OpenWrt/LEDE release: 19.07.1

Steps to reproduce:

  1. Install luci-app-statistics
  2. install collectd-mod-cpufreq

See error in system log:
Sat Feb 8 14:37:31 2020 daemon.err collectd[9875]: cpufreq plugin: File /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state not exists or no access. P-State statistics will not be reported. Check if `cpufreq-stats' kernel module is loaded.

Now the plugin does function but clearly the kernel-module would allow for more robust reporting as capable by collectd (allow to check "extra items" in the configuration of statistics.)

Not a bug in kernel. The current collectd data collection plugin is not compatible with the new intel_pstate driver (vs "old" cpufreq). The steps to get back cpufreq-stats is in the comments below.
