System info

Telegraf 1.26.1, Debian Bullseye with Kernel 6.1

Docker

No response

Steps to reproduce

1. run telegraf with powerstat plugin

...

Expected behavior

powerstat plugin should deliver power consumption metrics and information about c0/c1/c6 residency

Actual behavior

Metrics are missing without additional info or error

Additional info

Please document supported CPUs for uncore metrics, see

powerstat plugin should deliver power consumption metrics and information about c0/c1/c6 residency

@azw71
All metrics collected by Intel PowerStat plugin are collected in fixed intervals. Metrics that reports processor C-state residency or power are calculated over elapsed intervals. When starting to measure metrics, plugin skips first iteration of metrics if they are based on deltas with previous value.
(https://github.com/influxdata/telegraf/tree/master/plugins/inputs/intel_powerstat#metrics)

I see that you run Telegraf in testing mode which means that only one iteration of gathering metrics was run.
Please, run Telegraf in normal mode and see if all metrics are gathered properly.

Please document supported CPUs for uncore metrics, see
https://github.com/torvalds/linux/blob/master/drivers/platform/x86/intel/uncore-frequency/uncore-frequency.c

I believe that uncore metrics are documented in https://github.com/influxdata/telegraf/blob/master/plugins/inputs/intel_powerstat/README.md
Please, let me know if something is missing.

[azw71]

Thanks for your explanation, the missing measured values are actually available after restarting Telegraf.

My note regarding the documentation refers to the fact that the intel_uncore_frequency module cannot be used on my CPU, there is a message "no such device" when starting with modprobe. A few xeon CPUs are listed in the linked kernel source code that differ from the CPUs mentioned in the powerstat module.

[p-zak]

Yes, you are right.

intel-uncore-frequency module can be only loaded for these models:

Model number	Processor name
0x55	Intel Skylake-X
0x6A	Intel IceLake-X
0x6C	Intel IceLake-D
0x47	Intel Broadwell-G
0x4F	Intel Broadwell-X
0x56	Intel Broadwell-D
0x8F	Intel Sapphire Rapids X
0xCF	Intel Emerald Rapids X

Plugin will be updated in the upcoming months, this information will be put to README and/or code.

Thanks for findings this!

@p-zak given the user's issue was resolved after not running in test mode, is this issue left open to document the models supported?

[p-zak]

@powersj Exactly, it can be closed after changes to README are delivered.
