If PID is omitted current process PID (os.getpid()) is used. Raise NoSuchProcess if PID does not exist. Note that most of the methods of this class do not make sure the PID of the process being queried has been reused over time. That means you might end up retrieving an information referring to another process in case the original one this instance refers to is gone in the meantime. The only exceptions for which process identity is pre-emptively checked and guaranteed are: - parent() - children() - nice() (set) - ionice() (set) - rlimit() (set) - cpu_affinity (set) - suspend() - resume() - send_signal() - terminate() - kill() To prevent this problem for all other methods you can: - use is_running() before querying the process - if you're continuously iterating over a set of Process instances use process_iter() which pre-emptively checks process identity for every yielded instance NcCs|j|dS)N)_init)rrrprprt__init__TszProcess.__init__Fc Cs|dkrtj}n6t r4t|ttf r4td||dkrHtd|||_d|_ d|_ d|_ d|_ d|_ d|_d|_tj||_d|_d|_y |jWnXtk rYnFtk rYn4tk r|sd|}t|d|nd|_ YnX|j|j f|_dS)Nzpid must be an integer (got %r)rz'pid must be a positive integer (got %s)Fzno process found with pid %sT)osgetpid_PY3 isinstancerqr TypeError ValueError_pidr_exe _create_time_gone_hash_oneshot_inctx_ppidr|rZ_proc_last_sys_cpu_times_last_proc_cpu_times create_timer0r4r2r_ident)rr _ignore_nspmsgrprprtrWs<     z Process._initcCsy tj}Wntk r$i}YnX|j|d<y$|j|d<|jrRt|j|d<WnHtk rpd|d<Yn.tk rd|d<Ynt k rYnXd|j j |j j dj d d |jDfS) NrnameZstartedZzombiestatusZ terminatedz %s.%s(%s)z, cSsg|]\}}d||fqS)z%s=%rrp)rrkvrprprtrusz#Process.__str__..) collections OrderedDictAttributeErrorrrrrr4r2r0 __class__ __module____name__joinitems)rinforprprt__str__s&      zProcess.__str__cCst|tstS|j|jkS)N)rrZNotImplementedr)rotherrprprt__eq__s zProcess.__eq__cCs ||k S)Nrp)rrrprprt__ne__szProcess.__ne__cCs|jdkrt|j|_|jS)N)rhashr)rrprprt__hash__s  zProcess.__hash__cCs|jS)zThe process PID.)r)rrprprtrsz Process.pidc cs|jrdVnd|_z@|jj|jj|jjtrB|jj|jjdVWd|jj |jj |jj tr|jj |jj d|_XdS)a#Utility context manager which considerably speeds up the retrieval of multiple process information at the same time. Internally different process info (e.g. name, ppid, uids, gids, ...) may be fetched by using the same routine, but only one information is returned and the others are discarded. When using this context manager the internal routine is executed once (in the example below on name()) and the other info are cached. The cache is cleared when exiting the context manager block. The advice is to use this every time you retrieve more than one information about the process.

When *interval* is 0.0 or None (default) compares process times to system CPU times elapsed since last call, returning immediately (non-blocking).

When *interval* is > 0.0 compares process times to system CPU times elapsed before and after the interval (blocking). In this case is recommended for accuracy that this function be called with at least 0.1 seconds between calls. A value > 100.0 can be returned in case of processes running multiple threads on different CPU cores. The returned value is explicitly NOT split evenly between all available logical CPUs. This means that a busy loop process running on a system with 2 logical CPUs will be reported as having 100% CPU utilization instead of 50%.

It starts a sub process and deals with it exactly as when using subprocess.Popen class but in addition also provides all the properties and methods of psutil.Process class as a unified interface: >>> import psutil >>> from subprocess import PIPE >>> p = psutil.Popen(["python", "-c", "print 'hi'"], stdout=PIPE) >>> p.name() 'python' >>> p.uids() user(real=1000, effective=1000, saved=1000) >>> p.username() 'giampaolo' >>> p.communicate() ('hi ', None) >>> p.terminate() >>> p.wait(timeout=2) 0 >>> For method names common to both classes such as kill(), terminate() and wait(), psutil.Process implementation takes precedence. Unlike subprocess.Popen this class pre-emptively checks whether PID has been reused on send_signal(), terminate() and kill() so that you don't accidentally terminate another process, fixing http://bugs.python.org/issue6973.

Every new Process instance is only created once and then cached into an internal table which is updated every time this is used. Cached Process instances are checked for identity so that you're safe in case a PID has been reused by another process, in which case the cached instance is updated. The sorting order in which processes are yielded is based on their PIDs. *attrs* and *ad_value* have the same meaning as in Process.as_dict(). If *attrs* is specified as_dict() is called and the resulting dict is stored as a 'info' attribute attached to returned Process instance.

Return a (gone, alive) tuple indicating which processes are gone and which ones are still alive. The gone ones will have a new *returncode* attribute indicating process exit status (may be None). *callback* is a function which gets called every time a process terminates (a Process instance is passed as callback argument). Function will return as soon as all processes terminate or when *timeout* occurs. Differently from Process.wait() it will not raise TimeoutExpired if *timeout* occurs. Typical use case is: - send SIGTERM to a list of processes - give them some time to terminate - send SIGKILL to those ones which are still alive Example: >>> def on_terminate(proc): ... print("process {} terminated".format(proc)) ... >>> for p in procs: ... p.terminate() ... >>> gone, alive = wait_procs(procs, timeout=3, callback=on_terminate) >>> for p in alive: ... p.kill() c s\y|j|d}Wntk r$Yn4X|dk s8|j rX||_j|dk rX|dS)N)r7)r6r3rrJr)rr7rJ)callbackgonerprt check_gones zwait_procs..check_goneNrz*timeout must be a positive integer, got %szcallback %r is not a callableg?)rrr rrrminr) Zprocsr7rTrVraliveZdeadlinerZ max_timeoutrp)rTrUrtr_s6$        TcCs.|rtj}ntj}|dk r*|dkr*d}|S)azReturn the number of logical CPUs in the system (same as os.cpu_count() in Python 3.4).

When *interval* is > 0.0 compares system CPU times elapsed before and after the interval (blocking). When *interval* is 0.0 or None compares system CPU times elapsed since last call or module import, returning immediately (non blocking). That means the first time this is called it will return a meaningless 0.0 value which you should ignore. In this case is recommended for accuracy that this function be called with at least 0.1 seconds between calls. When *percpu* is True returns a list of floats representing the utilization as a percentage for each CPU. First element of the list refers to first CPU, second element to second CPU and so on.
