defaultdict appeared only with 2.5 😐 You can go with a simple dict if you protect every self.data[key] by testing if the key exists (if key not in self.data: self.data[key] = Note uss is probably the most representative metric for determining how much memory is actually being used by a process. Call this to start getting system snapshots from the target device. Target platform is *nix, however I would like to do it on a Win host also. weblink

Are you showing logs from different runs? –dano Oct 7 '14 at 14:29 Are you using a multi-core machine? On Windows this is an alias for kill(). hash() builtin can be used against instances of this class in order to identify a process univocally over time (the hash is determined by mixing process PID and creation time). Usage: %s ' % os.path.basename(__file__)) sys.exit(1) def proct(pid): try: with open(os.path.join('/proc/', pid, 'stat'), 'r') as pidfile: proctimes = pidfile.readline() # get utime from /proc//stat, 14 item utime = proctimes.split(' ')[13] # http://stackoverflow.com/questions/26238184/cpu-usage-per-thread

p.create_time() # return cached value ... The "portable" fields available on all plaforms are rss and vms. cpu_times()¶ Return a (user, system, children_user, children_system) namedtuple representing the accumulated process time, in seconds (see explanation). Psutil Python free: memory not being used at all (zeroed) that is readily available; note that this doesn't reflect the actual memory available (use available instead).

Returns 0 if unsuccessful. Python Get Cpu Usage Of Process If you want different time resolution, change sleep {this} in function logpid(). class MonitorThread(threading.Thread): """ The monitor thread saves the process info every second """ def __init__(self, pid): import collections self.pid = pid threading.Thread.__init__(self) self.data = collections.defaultdict(dict) self.process = True def Note that this calculation, as simple as it seems, can get tricky when using a multiprocessor system.

rtm.memwatch(less_than_bytes, for_so_many_seconds) This starts a memory watch. Python Get Current Process Name binpath()¶ The fully qualified path to the service binary/exe file as a string, including command line arguments. memory_info_ex()¶ Same as memory_info() (deprecated). started: the creation time as a floating point number expressed in seconds since the epoch.

Python Get Cpu Usage Of Process

This matches "top"‘s CODE column (see doc). If timeout is specified and process is still alive raise TimeoutExpired exception. Python Get Cpu Usage Linux Then, jiffies seem to be not a safe number for time measurements. Python Get Cpu Usage Windows Note: I've forgone PEP8's double line separating for space, but include in your code base.

soft_interrupts: number of software interrupts since boot. http://juicecoms.com/cpu-usage/terminal-cpu-usage-linux.html Print all ASCII alphanumeric characters without using them When was today's radar measurement of the Earth-Sun distance made and by who? How does Decommission (and Revolt) work with multiple permanents leaving the battlefield? def read_cpu_usage(): with open('/proc/stat') as stat_file: return sum(float(time) for time in next(stat_file).split()[1:]) Make the path a parameter so that it can be swapped out testing with a mock file. Python Psutil Examples

Bruteforcing a keypad lock Alignment of single- and multi-line column headers in tabular (LaTeX) I'm trying to count all letters in a txt file then display in descending order How to Detect ASCII-art windows made of M and S characters Encryption - How to claim authorship anonymously? username()¶ The name of the user that owns this service. check over here Returns 0 if unsuccessful, 1 if successful. rtm.getpsmemused(pid) Returns the memory usage of process in bytes by its ID.

syscalls: number of system calls since boot. Psutil Get Process By Name Now that I have a thread that can analyze the threads behaviour, I can use subprocess to launch it. if __name__ == "__main__": import sys import os import pickle import subprocess stdin = open(sys.argv[1]) stdout = open(sys.argv[2], "w") process = subprocess.Popen(sys.argv[3:], stdin = stdin, stdout = stdout)

rtm.startps(path) Attempts to launch the process at given absolute path on the target device.

print(p) ... Overview of API In your Python script, you start by doing "import rtm" and creating the "main()" function. family: the address family, either AF_INET, AF_INET6 or AF_UNIX. Importerror: No Module Named Psutil Changed in version 4.0.0: NetBSD no longer has read_time and write_time fields.

On UNIX this is the same as os.kill(pid, sig). p.cpu_percent() # return cached value ... After starting a CPU watch, call rtm.wait() to wait for the notification. http://juicecoms.com/cpu-usage/how-to-check-cpu-usage-in-linux.html The order of the list is consistent across calls. >>> import psutil >>> # blocking >>> psutil.cpu_percent(interval=1) 2.0 >>> # non-blocking (percentage since last call) >>> psutil.cpu_percent(interval=None) 2.9 >>> # blocking,

from itertools import islice def read_cpu_usage(stat_path='/proc/stat'): with open(stat_path) as stat_file: return next(stat_file) def parse_cpu_usage(cpu_stat_line): return sum(float(time) for time in islice(cpu_stat_line.split(), 1, None)) Bonus: Provide a convenience function from itertools import islice rtm.killps(pid) Attempts to kill the process with given ID on the target device. When percpu is True returns a list of floats representing the utilization as a percentage for each CPU. What do you call this alternating melodic pattern?

Availability: UNIX nice(value=None)¶ Get or set process niceness (priority). What I'm missing here? New in version 4.0.0. horrible, horrible.

rtm.memwatchcancel() This cancels a memory watch if it was started earlier. How can I stop Alexa from ordering things if it hears a voice on TV? At this point you can call one or more of the get CPU and memory functions for the processes and theads. {"reason":"crashwatchack", "pid":pid, "pspath":} A crash watch On UNIX this is calculated by using real process uid.

If you have 2 i.e. When you press the Run button in the Python tab of Remote Task Monitor, then this "main()" function in your script will get invoked.
