I don’t have much experience with prometheus so the question might be stupid.
How can I monitor these values:
# head /sys/devices/system/cpu/cpu0/cpuidle/state?/disable
==> /sys/devices/system/cpu/cpu0/cpuidle/state0/disable <==
0
==> /sys/devices/system/cpu/cpu0/cpuidle/state1/disable <==
0
==> /sys/devices/system/cpu/cpu0/cpuidle/state2/disable <==
0
I see that node_exporter doesn’t export these values, so what options do I have aside of patching node_exporter? Is there some built-in solution for exporting file contents maybe?
