.SH NAME
|
||||
turbostat \- Report processor frequency and idle statistics
|
||||
.SH SYNOPSIS

.RB [ Options ]
|
||||
.RB command

|
||||
.SH DESCRIPTION
|
||||
\fBturbostat \fP reports processor topology, frequency,
|
||||
idle power-state statistics, temperature and power on modern X86 processors.
|
||||
Either \fBcommand\fP is forked and statistics are printed
|
||||
upon its completion, or statistics are printed periodically.
|
||||
|
||||
\fBturbostat \fP
|
||||
must be run on root, and
|
||||
minimally requires that the processor
|
||||
supports an "invariant" TSC, plus the APERF and MPERF MSRs.
|
||||
Additional information is reported depending on hardware counter support.
|
||||
|
||||
.SS Options
|
||||
The \fB-p\fP option limits output to the 1st thread in 1st core of each package.
|
||||
.PP
|
||||
The \fB-P\fP option limits output to the 1st thread in each Package.
|
||||
.PP
|
||||
The \fB-S\fP option limits output to a 1-line System Summary for each interval.
|
||||
.PP
|
||||
The \fB-v\fP option increases verbosity.
|
||||
.PP
|
||||
The \fB-c MSR#\fP option includes the delta of the specified 32-bit MSR counter.
|
||||
.PP
|
||||
The \fB-C MSR#\fP option includes the delta of the specified 64-bit MSR counter.
|
||||
.PP
|
||||
The \fB-m MSR#\fP option includes the the specified 32-bit MSR value.
|
||||
.PP
|
||||
The \fB-M MSR#\fP option includes the the specified 64-bit MSR value.
|
||||
.PP
|
||||
The \fB-i interval_sec\fP option prints statistics every \fiinterval_sec\fP seconds.
|
||||
The default is 5 seconds.
|
||||
.PP
|
||||
The \fBcommand\fP parameter forks \fBcommand\fP and upon its exit,
|
||||
displays the statistics gathered since it was forked.
|
||||
.PP
|
||||
.SH FIELD DESCRIPTIONS
|
||||
.nf
|
||||
\fBPackage\fP processor package number.
|
||||
\fBCore\fP processor core number.

\fBBzy_MHz\fP average clock rate while the CPU was busy (in "c0" state).
|
||||
\fBTSC_MHz\fP average MHz that the TSC ran during the entire interval.
|
||||
\fBCPU%c1, CPU%c3, CPU%c6, CPU%c7\fP show the percentage residency in hardware core idle states.

|

.SH EXAMPLE
|
||||
Without any parameters, turbostat prints out counters ever 5 seconds.
|
||||
(override interval with "-i sec" option, or specify a command
|
||||
for turbostat to fork).
|
||||
|
||||
The first row of statistics is a summary for the entire system.
|
||||
For residency % columns, the summary is a weighted average.
|
||||
For Temperature columns, the summary is the column maximum.
|
||||
For Watts columns, the summary is a system total.
|
||||
Subsequent rows show per-CPU statistics.

The \fBmax efficiency\fP frequency, a.k.a. Low Frequency Mode, is the frequency
|
||||
available at the minimum package voltage. The \fBTSC frequency\fP is the nominal
|
||||
maximum frequency of the processor if turbo-mode were not available. This frequency
|
||||
should be sustainable on all CPUs indefinitely, given nominal power and cooling.
|
||||
The remaining rows show what maximum turbo frequency is possible
|
||||
depending on the number of idle cores. Note that this information is
|
||||
not available on all processors.
|
||||
.SH FORK EXAMPLE
|
||||
If turbostat is invoked with a command, it will fork that command
|
||||
and output the statistics gathered when the command exits.
|
||||
eg. Here a cycle soaker is run on 1 CPU (see %c0) for a few seconds
|
||||
until ^C while the other CPUs are mostly idle:
|
||||
|
||||
.nf
|
||||
root@ivy: turbostat cat /dev/zero > /dev/null

Above the cycle soaker drives cpu5 up its 3.8 GHz turbo limit
|
||||
while the other processors are generally in various states of idle.
|
||||
|
||||
Note that cpu1 and cpu5 are HT siblings within core1.
|
||||
As cpu5 is very busy, it prevents its sibling, cpu1,
|
||||
from entering a c-state deeper than c1.
|
||||
|
||||
Note that the Avg_MHz column reflects the total number of cycles executed
|
||||
divided by the measurement interval. If the %Busy column is 100%,
|
||||
then the processor was running at that speed the entire interval.
|
||||
The Avg_MHz multiplied by the %Busy results in the Bzy_MHz --
|
||||
which is the average frequency while the processor was executing --
|
||||
not including any non-busy idle time.
|
||||
|
||||
.SH NOTES
|
||||
|
||||
.B "turbostat "
|
||||
must be run as root.
|
||||
|
||||
.B "turbostat "
|
||||
reads hardware counters, but doesn't write them.
|
||||
So it will not interfere with the OS or other programs, including
|
||||
multiple invocations of itself.
|
||||
|
||||
\fBturbostat \fP
|
||||
may work poorly on Linux-2.6.20 through 2.6.29,
|
||||
as \fBacpi-cpufreq \fPperiodically cleared the APERF and MPERF
|
||||
in those kernels.
|
||||
|
||||
If the TSC column does not make sense, then
|
||||
the other numbers will also make no sense.
|
||||
Turbostat is lightweight, and its data collection is not atomic.
|
||||
These issues are usually caused by an extremely short measurement
|
||||
interval (much less than 1 second), or system activity that prevents
|
||||
turbostat from being able to run on all CPUS to quickly collect data.
|
||||
|
||||
The APERF, MPERF MSRs are defined to count non-halted cycles.
|
||||
Although it is not guaranteed by the architecture, turbostat assumes
|
||||
that they count at TSC rate, which is true on all processors tested to date.
