No "Combined" value in latest version of powermetrics in macOS

There is no line with "Combined" in latest version of powermetrics in macOS.
In particular, we tested on a MacBook Air (M2, 2022), and the powermetrics command doesn't have the combined line (which is read in JoularJX).
@metacosm, as you wrote the initial PR, could you have a look please?
@olegoaer could help in testing on macOS.
metacosm commented
Hmm, that's weird, I have the "Combined Power" line on my M1 Max on 14.1.1.
@olegoarer, could you please send me the output of running sudo powermetrics --samplers cpu_power -i 1000 -n 1 to see how different it is?

Indeed. I see that "combined" is just the addition of 3 values.
metacosm commented
Could you add the output of powermetrics -h as well, please?
olegoaer commented
powermetrics -h
Usage: powermetrics [-i sample_interval] [-r order] [-t wakeup_cost]
Gather and display CPU usage statistics (divided into time spent in
user mode and supervisor mode), timer and interrupt wakeup frequency
(total and, for near-idle workloads, those that resulted in package
C-state exits), and on supported platforms, interrupt frequencies
(categorized by CPU number), package C-state statistics (an indication
of the time the core complex + integrated graphics, if any, were in
low-power idle states), as well as the average execution frequency for
each CPU when not idle.
The following command-line options are supported:
-h | --help show this message
-A | --show-all Enables all samplers and displays all the
available information for each sampler.
-a | --poweravg <N> display poweravg every N samples (0=disabled) [default: 10]
-b | --buffer-size <size> set output buffer size (0=none, 1=line)
-f | --format <format> display data in specified format [default: text]
-i | --sample-rate <N> sample every N ms (0=disabled) [default: 5000ms]
-n | --sample-count <N> obtain N periodic samples (-1=infinite) [default: -1]
-o | --output-file <file> output to file [default: stdout]
-r | --order <method> order process list using specified method [default: composite]
-s | --samplers <samplers> comma separated list of samplers and sampler groups
-t | --wakeup-cost <N> assume package idle wakeups have a CPU time
cost of N us when using hybrid sort orders
using idle wakeups with time-based metrics
--show-initial-usage print initial sample for entire uptime
--show-usage-summary print final usage summary when exiting
--show-extra-power-info unsupported power info (may change between releases)
--show-pstates show pstate distribution (XCPM only)
--show-plimits cpu limiting information
--show-cpu-qos show per cpu QOS breakdowns
--show-cpu-scalability show per cpu workload scalability
--show-hwp-capability show per cpu-thread HWP estimated efficient and guarateed frequencies (instantaneous)
--show-process-coalition group processes by coalitions and show per coalition information
--show-process-wait-times show per-process sfi wait time info
--show-process-qos-tiers show per-process QOS latency and throughput tiers
--show-process-io show per-process io information
--show-process-gpu show per-process gpu time
--show-process-netstats show per-process network information
--show-process-qos show QOS times aggregated by process
--show-process-amp show per-process AMP information
--show-process-energy show per-process energy impact number
This implicitly enables sampling of all the
above per-process statistics.
--show-process-samp-norm Show CPU time normailzed by the sample window.
--handle-invalid-values powermetrics will output invalid=true rather
than abort when it sees invalid values.
--hide-cpu-duty-cycle hide CPU duty cycle data
--unhide-info <samplers> comma separated list of samplers to unhide (backwards compatibility)
The following sort orders are supported by --order:
pid process identifier
wakeups total package idle wakeups (alias: -W)
cputime total CPU time used (alias: -C)
composite weighted hybrid of package idle
wakeups and CPU time used (alias: -O)
The following output formats are supported by --format:
text human-readable text output
plist machine-readable property list, NUL-separated
This tool also implements special behavior upon receipt of certain signals
to aid with the automated collection of data:
SIGINFO take an immediate sample
SIGIO flush any buffered output
SIGINT/SIGTERM/SIGHUP stop sampling and exit
The following samplers are supported by --samplers:
tasks per task cpu usage and wakeup stats
battery battery and backlight info
network network usage info
disk disk usage info
int_sources interrupt sources information
interrupts interrupt distribution
cpu_power cpu power and frequency info
thermal thermal pressure notifications
sfi selective forced idle information
gpu_power gpu power and frequency info
bandwidth amc bandwidth counters
ane_power ane power and frequency info
and the following sampler groups are supported by --samplers:
all tasks,battery,network,disk,int_sources,interrupts,cpu_power,thermal,sfi,gpu_power,bandwidth,ane_power
default tasks,battery,network,disk,interrupts,cpu_power,gpu_power,ane_power
metacosm commented
🤔 OK, most of the information is the same but you have more available samplers than I do: I don't have int_sources or bandwidth. I was hoping to see what the DCS power refers to and how they define Package… maybe in the man page but this won't fit here and I'm not sure if there's a way to find all the different versions of the man page online.
adelnoureddine commented
DCS seems to be related to DRAM : DCS = DRAM Command Scheduler (source here and here).
metacosm commented
Note also that the output is not the latest powermetrics version as the OS version reported by @olegoaer is actually pretty old.
adelnoureddine commented
metacosm commented
No idea, there isn't much documentation on powermetrics, unfortunately. The PR should handle both versions adequately now at the expense of a little more processing. If we could find reference documentation, we could base the parsing of the output on the OS version that's mentioned at the top but so far, I haven't been able to find authoritative information on the topic, notably because the output most likely also depend on the CPU type (Intel vs. Apple Silicon) as well.
olegoaer commented
FYI, I updated my OS to the latest version (OS version: 23B92) and the Combined Power value is now there.

Thanks. It's good to know that recent (and I assume future) versions have the combined value.
