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 This is something that I had not heard of. It takes a reading from the stat files, then it runs top, which taks a second, then it re-reads the stat files, and prints the results for that second to match When the remote endpoint is not connected you'll get an empty tuple (AF_INET*) or None (AF_UNIX).
If grouped is True the mapped regions with the same path are grouped together and the different memory fields are summed. On Windows this is an alias for pagefile field and it matches "Mem Usage" "VM Size" column of taskmgr.exe. Availability: Windows num_threads()¶ The number of threads used by this process. Remember that Python itself is written in C so any library is simply going to make a smart decision about which OS-specific code snippet to run, as you suggested above.
When accessing methods of this class always be prepared to catch NoSuchProcess, ZombieProcess and AccessDenied exceptions. Warning the first time this function is called with interval = 0.0 or None it will return a meaningless 0.0 value which you are supposed to ignore. total and used fields on UNIX refer to the overall total and used space, whereas free represents the space available for the user and percent represents the user utilization (see source Python High Cpu Usage Terms Privacy Security Status Help You can't perform that action at this time.
interrupts: number of interrupts since boot. Python Get Cpu Usage Of Process limits is a (soft, hard) tuple. Indeed, there may not even be any consensus between the various operating systems called Windows. For UDP and UNIX sockets this is always going to be psutil.CONN_NONE.
Heavy CPU and RAM usage when system idle w/o any application running0How to print out memory usage by applications? Python Get System Memory Usage And if you didn't install the psutil package, maybe you're still waiting for the results! asked 2 years ago viewed 11638 times active 2 years ago Related 1Calculating reverse dependencies of a Debian package6Calculate query coverage from BLAST output3Script for obtaining images from an IP security raddr: the remote address as a (ip, port) tuple or an absolute path in case of UNIX sockets.
ad_value is the value which gets assigned to a dict key in case AccessDenied or ZombieProcess exception is raised when retrieving that particular process information. Warning on some systems such as Linux, on a very busy or long-lived system these numbers may wrap (restart from zero), see issues #802. Python Psutil Examples See meminfo.py script providing an example on how to convert bytes in a human readable form. >>> import psutil >>> psutil.swap_memory() sswap(total=2097147904L, used=886620160L, free=1210527744L, percent=42.3, sin=1050411008, sout=1906720768) Disks¶ psutil.disk_partitions(all=False)¶ Return all Python Get Current Memory Usage mode (Linux): a string indicating how the file was opened, similarly open‘s mode argument.
thanks for your help. have a peek at these guys Using the timeit module Anther option is to use the timeit module, which gives you an average time measure. Changed in version 4.0.0: added busy_time (Linux, FreeBSD), read_merged_count and write_merged_count (Linux) fields. The additional metrics provide a better representation of "effective" process memory consumption (in case of USS) as explained in detail in this blog post. Python Get Cpu Usage Windows
You can then redirect its output to a file in order to import it into a spreadsheet later (python log.py 9391 > firefox_log.txt) and import the data into a spreadsheet selecting But how? On Windows there's no such limitation (exit code is always returned). check over here There seems to be a few possible ways of extracting that from my search: Using a library such as PSI (that currently seems not actively developed and not supported on multiple
However, it seems the most you can do with it is grab the memory that a single python process is using and/or it's child processes. Python Resource Module comment it at least. –rolfl Oct 26 '14 at 14:20 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up It represents the amount of memory that would be freed if the process was terminated right now.
Also, see netstat.py sample script. psutil.net_if_stats()¶ Return information about each NIC (network interface card) installed on the system as a dictionary whose keys are the NIC names and value is a namedtuple with the following fields: Note Unlike subprocess.Popen this class preemptively checks whether PID has been reused on send_signal(), terminate() and kill() so that you can't accidentally terminate another process, fixing http://bugs.python.org/issue6973. >>> Psutil Python It uses /proc/stat to get CPU times and /proc/
wired (BSD, OSX): memory that is marked to always stay in RAM. Better function names would also help with clarity - e.g. Browse other questions tagged python linux or ask your own question. this content On platforms where extra fields are not implemented this simply returns the same metrics as memory_info().
Code only answers aren't as helpful as ones which provide an explanation of what they are doing. –TemporalWolf Nov 21 '16 at 22:55 add a comment| up vote -1 down vote Anagram puzzle whose solution is guaranteed to make you laugh What is the XP and difficulty of an encounter when a monster can transform? If grouped is False each mapped region is shown as a single entity and the namedtuple will also include the mapped region's address space (addr) and permission set (perms). When using this context manager the internal routine is executed once (in the example below on name()) the value of interest is returned and the others are cached.
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. Reload to refresh your session. proctimes = pidfile.readline() utime = proctimes.split(' ') stime = proctimes.split(' ') could be rewritten proctimes = pidfile.readline().split(' ') utime = proctime # you could also call int here stime = proctime Always set to 0 on Linux.
psutil.cpu_times_percent(interval=1, percpu=False) ... Note you can have more than one address of the same family associated with each interface (that's why dict values are lists).
