My machine is essentially idle, but cpu_percent() always returns exactly 100&#37;.

Here is copy/paste from terminal:

Can you show the output of the below command as well? 

>>> print psutil.cpu_times(); time.sleep(5); print psutil.cpu_times()
system=3.395108; idle=37.254002; user=4.461708; nice=0.0
system=3.395162; idle=37.254894; user=4.461761; nice=0.0

I'm getting similar results here (not 100% but close, 99.99% which 
probably means the issue is the same). Giampaolo, can you check this 
on any other platforms you have handy and see if this is OS X only? 
I'd like to figure out if this is in the C code or the Python code 
that handles the CPU calculations.

Thanks

I'll have to look at this some more later but I think the 
get_system_cpu_times() is not returning valid results for some reason: 

>>> _psutil_osx.get_system_cpu_times(); time.sleep(5);  
_psutil_osx.get_system_cpu_times()

After 5 seconds it's giving almost identical values, and I suspect 
any differences in the values are probably from floating point math...

Aside from an initial "100%" which perhaps we could adjust someway 
results look ok and match top/taskmgr on BSD/Linux/Windows on both 
single and double CPUs.
The script:

import time, psutil, threading

def foo():
    while 1:
        pass
t = threading.Thread(target=foo).start()

while 1:
    print psutil.cpu_percent()
    time.sleep(1)


In r724 I added a test based on the results you pasted in msg #4 
which should fail on OSX so you can at least use that to test results.

Thanks... I took a look at this some more last night but I am still working on it. 

I can see the problem (times not updating properly) but I don't know 
if the system call is just returning strange data or if something has 
changed in 10.6 in the way statistics are reported/calculated.

Point is times are updated, but not as much as expected, so I agree 
with you that this is likely to be a math problem. Maybe we shouldn't 
divide per CLOCKS_PER_SEC as we do on BSD:

- (double)r_load.cpu_ticks[CPU_STATE_USER] / CLOCKS_PER_SEC,
+ (double)r_load.cpu_ticks[CPU_STATE_USER],

giampaolo · 2014-05-23T14:37:40Z

From [email protected] on October 23, 2010 10:17:59

I suspect it's a math problem but I don't know why, or what to use 
instead of CLOCKS_PER_SEC... we can't just return it as is because 
it'd be returning clock ticks for the values, and our math in the 
cpu_percent() function depends on seconds. 

In theory, dividing by CLOCKS_PER_SEC is the correct thing to do but 
it's evidently not working correctly, so something is out of whack :-/

giampaolo · 2014-05-23T14:37:41Z

From [email protected] on October 23, 2010 11:08:07

Should be fixed in r725 now. I've no idea what changed, if anything, 
but CLOCKS_PER_SEC (1000000) isn't working correctly and OS X 10.6 
seems to be expecting you to divide CLK_TCK (100) instead. Replacing 
the division with CLK_TCK I'm getting results that match Activity 
Monitor when using the following test: 

python -c 'import time,psutil; time.sleep(5); print 
psutil.cpu_percent(); time.sleep(5); print psutil.cpu_percent()'

You could try to run this and paste the output:

import psutil, time
while 1:
    print sum(psutil.cpu_times())
    time.sleep(1)

On my Linux box (2 CPUs) it prints:

You can call the cpu times function directly from the _psutil_osx module: 

python -c 'import _psutil_osx,time; print 
_psutil_osx.get_system_cpu_times(); time.sleep(5); print 
_psutil_osx.get_system_cpu_times()'

I'm not sure what to make of the user time in your example above (the 
first value) it looks like it rolled over. The idle time is what we 
use to calculate CPU utilization and you can see in the example that 
your idle time is the same in both iterations. If the idle is the 
same then you're going to see 100% utilization. 

Can you run this and post the output?

python -c "import _psutil_osx,time
for i in range(0, 25):
    time.sleep(2)
    print _psutil_osx.get_system_cpu_times()"

I'd like to see what your idle time looks like over a longer period.

Thanks

Interesting... your CPU times are reporting identical results every 
time. It's no wonder CPU util is showing 100% then. I'm kind of at a 
loss, the cpu times are being pulled directly from a mach 
host_statistics() call and the only calculation/manipulation done is 
to divide it by CLK_TCK. It looks to me like the host_statics call is 
returning the same values every time.

I'll put together a small C app you can try it with and see what 
happens if we print the raw idle value from host_statistics()

Ok r739 now fixes some warnings and adds error checking around 
host_statistics() in get_system_cpu_times() - while making a test C 
app I noticed that if host_statistics() is failing the CPU times 
struct can still return values. I suspect what may have been 
happening in your case is the call to host_statistics is failing and 
thus not updating the idle time on subsequent runs. You can try the 
newest SVN version and see if that makes any difference. 

I've also attached a cpu_idle.c file you can compile with just "gcc 
cpu_idle.c"  if you've got the commandline xcode/gcc tools installed. 
Then just run ./a.out and you should see something like this, updated every two seconds: 

[user@host ]$ ./a.out 
idle=55495234, idle/CLK_TCK=554952.340000
idle=55495585, idle/CLK_TCK=554955.850000
idle=55495925, idle/CLK_TCK=554959.250000
idle=55496269, idle/CLK_TCK=554962.690000
idle=55496604, idle/CLK_TCK=554966.040000
idle=55496927, idle/CLK_TCK=554969.270000

To stop just use CTRL C 

Thanks,

Okay -  with the latest svn, the output from the code of Comment 21 
follows. It is different from before:

 python -c "import _psutil_osx,timefor i in range(0, 25):
    time.sleep(2)
    print _psutil_osx.get_system_cpu_times()"
(49156.760000000002, 0.0, 37154.800000000003, 1760902.1299999999)

(49157.489999999998, 0.0, 37155.669999999998, 1760924.53)
(49157.720000000001, 0.0, 37155.940000000002, 1760931.97)
(49158.050000000003, 0.0, 37156.349999999999, 1760939.3)

Output from cpu_percent() is unchanged from before:

 python -c "import psutil; print psutil.cpu_percent()"
100.0

Bear in mind you have to have the time.sleep() in there, since the 
CPU util calculation is performed by comparing the amount of idle 
time reported against the amount of clock time reported. The cpu idle 
values look to be incrementing nicely now... can you try 

python -c 'import time,psutil; time.sleep(5); print 
psutil.cpu_percent(); time.sleep(5); print psutil.cpu_percent()'

And see if you get something accurate as compared to Activity Monitor? 

thanks!

Yes, that's it! Thank you!

Since cpu_percent is often paired with a 'time.sleep' call, I wonder 
if it would be simpler to have cpu_percent accept a "sleep" argument 
with default behavior of, say, 2s.

giampaolo · 2014-05-23T14:37:51Z

Possibly that would make sense.. at the moment what we do is as soon 
as you import the module we start the clock so to speak, so as long 
as you wait a tenth of a second or more before calling the 
cpu_percent() code it should be able to calculate the CPU percentage. 
The longer you wait between calls the more data we have to work with 
so it'll be more accurate.

I'll discuss the sleep param with Giampaolo and see if we want to go 
that route, in the meantime just be sure to give it a little time 
between calls, even a tenth of a second or two should be enough.
