See meminfo.py script providing an example on how to convert bytes in a human readable form. why is Newton's method not widely used in machine learning? However, it can make your code to run much more slower. Also provide a convenience module-level function for the 99% use case.

All other - thanks. Example: >>> import psutil >>> psutil.users() [suser(name='giampaolo', terminal='pts/2', host='localhost', started=1340737536.0), suser(name='giampaolo', terminal='pts/3', host='localhost', started=1340737792.0)] Processes¶ Functions¶ psutil.pids()¶ Return a list of current running PIDs. The order of the list is consistent across calls. It currently supports Linux, Windows, OSX, Sun Solaris, FreeBSD, OpenBSD and NetBSD, both 32-bit and 64-bit architectures, with Python versions from 2.6 to 3.5 (users of Python 2.4 and 2.5 may

Sebastian Nov 10 '08 at 20:44 3 @J.F.Sebastian: Which Windows? Changed in version 4.0.0: added busy_time (Linux, FreeBSD), read_merged_count and write_merged_count (Linux) fields. Effects of bullets firing while in a handgun's magazine Did Malcolm X say that Islam has shown him that a blanket indictment of all white people is wrong? The main part of cput: cputimes = procfile.readline() cputotal = 0 for i in cputimes.split(' ')[2:]: i = int(i) cputotal = (cputotal + i) return(float(cputotal)) can be rewritten in a functional

  • Tango Icons Tango Desktop Project.
  • Looking at the output, note that the memory usage is expressed in terms of MiB, which stand for mebibyte (1MiB = 1.05MB). 7.
  • Possible values are 'r', 'w', 'a', 'r+' and 'a+'.
  • interval and percpu arguments have the same meaning as in cpu_percent().

  • p.create_time() # return cached value ...
  • You signed in with another tab or window.
  • TO me this was just counting the nice times and on, and not counting the user time at all.
  • i'm 100% sure this is correct - i adapted it from a C program someone who knows what they're talking about wrote.
  • raddr: the remote address as a (ip, port) tuple or an absolute path in case of UNIX sockets.

Depending on the method called the OS may be able to succeed in retrieving the process information or not. OSX is not supported. >>> import psutil >>> p = psutil.Process() >>> p.io_counters() pio(read_count=454556, write_count=3456, read_bytes=110592, write_bytes=0) Availability: all platforms except OSX and Solaris num_ctx_switches()¶ The number voluntary and involuntary context Installing sysbench on redhat 7 - 404 not found What is an asymmetric wheel and why would you use it? Python High Cpu Usage That means that if the Process instance is old enough and the PID has been reused in the meantime you might end up interacting with another process.

Target platform is *nix, however I would like to do it on a Win host also. I'll start with the final version and then work towards it from the original code.

Note: I've forgone PEP8's double line separating for space, but include in your code base. Psutil Memory Usage The performance/memory gain is negligible but, for me, it the principle and consistency. Changed in version 4.1.0: return two extra fields: children_user and children_system.

Python Psutil Examples To emulate Windows taskmgr.exe behavior you can do: p.cpu_percent() / psutil.cpu_count(). Python Get Current Memory Usage Example on a system having 2 physical hyper-thread CPU cores: >>> import psutil >>> psutil.cpu_count() 4 >>> psutil.cpu_count(logical=False) 2 psutil.cpu_stats()¶ Return various CPU statistics as a namedtuple: ctx_switches: number of context

To run the time utility type: $ time -p python timing_functions.py 1 $ time -p python timing_functions.py which gives the output: Total time running random_sort: 1.3931210041 seconds real 1.49 user 1.40 memory_maps(grouped=True)¶ Return process's mapped memory regions as a list of namedtuples whose fields are variable depending on the platform. psutil.swap_memory()¶ Return system swap memory statistics as a namedtuple including the following fields: total: total swap memory in bytes used: used swap memory in bytes free: free swap memory in bytes memory_info_ex()¶ Same as memory_info() (deprecated). Python Get Cpu Usage Windows

def cput(): with open('/proc/stat', 'r') as procfile: cputimes = procfile.readline() cputotal = sum(float(i) for i in cputimes.split(' ')[1:]) return(cputotal) Return the total directly removing the temporary variable. rlimit(resource, limits=None)¶ Get or set process resource limits (see man prlimit). share|improve this answer answered Nov 9 '08 at 18:50 S.Lott 267k54375657 4 df -h answers the "disk space" question both on Windows and *nix. –J.F. pss (Linux): aka "Proportional Set Size", is the amount of memory shared with other processes, accounted in a way that the amount is divided evenly between the processes that share it.

name is the name the process had before disappearing and gets set only if Process.name() was previously called. Python Get System Memory Usage a significant one. The cache is cleared when exiting the context manager block.

return pid if __name__ == "__main__": main(parse_args()) Now if you want to import this functionality elsewhere, it's easy.

See disk_usage.py script providing an example usage. >>> import psutil >>> psutil.disk_partitions() [sdiskpart(device='/dev/sda3', mountpoint='/', fstype='ext4', opts='rw,errors=remount-ro'), sdiskpart(device='/dev/sda7', mountpoint='/home', fstype='ext4', opts='rw')] psutil.disk_usage(path)¶ Return disk usage statistics about the given path as a On UNIX this is the same as os.kill(pid, signal.SIGKILL). Warning the way this class is bound to a process is via its PID. Python Resource Module If you feel psutil is useful to you or your business and want to support its future development please consider donating me (Giampaolo Rodola’) some money.
