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 that
the PID of the process being queried has been reused. That means
that you may end up retrieving information for another process.
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.

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. If you're lucky, you'll
get a hell of a speedup.

utilization as a percentage.
When *interval* is 0.0 or None (default) compares process times
to system CPU times elapsed since last call, returning
immediately (non-blocking). That means that the first time
this is called it will return a meaningful 0.0 value.
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%.
Examples:
>>> import psutil
>>> p = psutil.Process(os.getpid())
>>> # blocking
>>> p.cpu_percent(interval=1)

| j ¡ S )a] This method returns the same information as memory_info(),
plus, on some platform (Linux, macOS, Windows), also provides
additional metrics (USS, PSS and swap).
The additional metrics provide a better representation of actual
process memory usage.
Namely USS is the memory which is unique to a process and which
would be freed if the process was terminated right now.
It does so by passing through the whole process address.
As such it usually requires higher user privileges than
memory_info() and is considerably slower.

Every new Process instance is only created once and then cached

The sorting order in which processes are yielded is based on
their PIDs.

terminate.
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:

total physical memory available.

the memory that can be given instantly to processes without the
system going into swap.
This is calculated by summing different memory values depending
on the platform and it is supposed to be used to monitor actual
memory usage in a cross platform fashion.
- percent:
the percentage usage calculated as (total - available) / total * 100
- used:
memory used, calculated differently depending on the platform and
designed for informational purposes only:
macOS: active + wired
BSD: active + wired + cached
Linux: total - free
- 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)
Platform-specific fields:
- active (UNIX):
memory currently in use or very recently used, and so it is in RAM.
- inactive (UNIX):
memory that is marked as not used.
- buffers (BSD, Linux):
cache for things like file system metadata.
- cached (BSD, macOS):
cache for various things.
- wired (macOS, BSD):
memory that is marked to always stay in RAM. It is never moved to disk.
- shared (BSD):
memory that may be simultaneously accessed by multiple processes.
The sum of 'used' and 'available' does not necessarily equal total.
On Windows 'available' and 'free' are the same.
