Comment on Documentation in psutil

Comment by Bornstub:

The cpu_percent should be get_cpu_percent, it is a typo.

In Windows environment, if path to executable is defined in Windows System
Variables and Process is started from command prompt using lets say c:\
module will not return any useful information Back about path of the
executable.

Variables and Process is started from command prompt using different

Comment by g.rod...@gmail.com:

I'm not sure what you mean by "Windows System Variables". If you think this
is a bug with psutil could you please file a bug report providing an
example on how to reproduce the prblem?

Comment by victor.dramba:

this seems to be a typo: "For total physical memory use psutil.BOOT_TIME
constant."

[psu...@googlecode.com]

Comment by g.rod...@gmail.com:

I'm not a native English speaker but I see no typo in that sentence.

[psu...@googlecode.com]

Comment by jlo...@gmail.com:

I think he meant that we're suggesting total physical memory is in the
BOOT_TIME constant instead of psutil.TOTAL_PHYMEM :)

Comment by billy020...@gmail.com:

how can we get the list of processName? Understand we can get list of
processID using get_pid_list(), but how about processName.

This would be a better question for the mailing list:
http://groups.google.com/group/psutil/

There is no specific function for list of process names, you need to
iterate through the processes to get the process name for each process and
of course catch any exceptions along the way.

Comment by prashant...@gmail.com:

I am getting incorrect memory values when I use psutil inside an OpenVZ
container.

>>> psutil.TOTAL_PHYMEM
8343113728L

root@juicermachine:~# free
total used free shared buffers cached

How can I fix this?

Is it possible to use psutil directly in C? and if so where do I start from?

[psu...@googlecode.com]

Comment by g.rodola:

No.

[psu...@googlecode.com]

Comment by robert.s...@gmail.com:

The documentation still states that the CPU percentage method is
cpu_percent() but it is get_cpu_percent(). Please fix.

[psu...@googlecode.com]

Comment by jlo...@gmail.com:

Robert, the documentation is correct... there are two functions in psutil,
one for system wide cpu usage which is cpu_percent() and one for individual
process utilization, which is get_cpu_percent()

>>> import psutil

>>> psutil.cpu_percent()
21.100000000000001

>>> psutil.Process(os.getpid()).get_cpu_percent()
0.20000000000000001

Comment by richkapp...@gmail.com:

A little help please. Running Ubuntu 12.04, python 2.7 on a 64 bit HP G62.
Installed psutil via apt-get install python-psutil.
Most of it works, but some doesn't, for example, (having imported psutil as
ps)

>>> ps.cpu_percent()
5.0

okay, that bit works fine, but when I try

>>> ps.virtual_memory()

I get an attribute error that says the module object has no
attribute 'virtual_memory'

Is this a version issue? Any idea what I'm doing wrong or missing?

regards, Richard

Comment by jlo...@gmail.com:

Rich, that question is better suited to the bug tracker or mailing list
rather than the documentation page.

[psu...@googlecode.com]

Comment by richkapp...@gmail.com:

SURVEY SAYS: It was a version issue. 0.4.1 is the version in the Ubuntu
repository and apparently doesn't contain the virtual_memory function, I
installed 0.6.1 and all is now well.

We have logged following in our system using psutil, isn't the memory usage
calculation in percentage wrong here? Or, am I missing something here?

psutil is awesome! I am using it in my project.

Is there a process version of psutil.net_io_counters()?
A process even has the get_io_counters().
I am wondering if there will be a net_io_counters() for a process.

Comment by g.rodola:

AFAIK most (all?) operating systtems do not expose those metrics so no,
unfortunately this is not possible. I'm not 100% sure though (maybe Linux
might provide the necessary hooks).

Comment by justany...@gmail.com:

I'm looking for a replacement for calling iostat -d 60 (delay 60 seconds).
Instead, I want to call a library twice, a minute apart, and find all the
stats available from iostat.

psutils provides most of these, but not IO utilization PERCENT, available
from /proc/diskstats. Also, vmstat -a changed to vmstat -s doesn't provide
ioblocksIn / ioBlocksOut; I think I have to get this from diskstats, too.

Comment by nadeem.r...@gmail.com:

a parallel application's cpu utillization is quite rideculas e.g.(1000.0%,
1200.0%)
I have 8 cores maximum it should be max 800.0% if application is running on
all 8 cores should not be above 800.0%.
any reasonable answers.

Comment by g.rodola:

This is not the right place for asking these kind of questions (use the
ml). Also the project has been moved to github long ago. Also, you should
provide more info about your problem (but not here).
