Python Operations Learning Note 1

Resign at home, while looking for work while learning python read a Python foundation after feeling far enough, and then in some East search to find a "python Automation Operations" book, write this want to leave some traces of learning, First of all, thank the Great God author Liu Tians,

No more talking about getting started.

python system basic Information module detailed

System basic information Acquisition module as an important part of monitoring module

System Performance Information module:psutil

This module can easily obtain the system running process and system utilization information, mainly used for system monitoring, analyzing and restricting system resources and process management.

First, download a psutil package

URL https://github.com/giampaolo/psutil/releases?after=release-2.1.3

i downloaded the 2.0.0 version written in the book.

Install the Psutil module: (This thing shows the units in bytes)

TAR-XF psutil-release-2.0.0.tar.gz

CD psutil-release-2.0.0

Python setup.py Install

You can then run the

Python

Get System Performance Information

Import Psutil

MEM = Psutil.virtual_memory ()

function to call psutil for variable mem assignment virtual_memory ()

Get individual information: ( two ways )

Psutil.virtual_memory (). percent

Show CPU Information:

Psutil.cpu_times ()

Psutil.cpu_count () displays the number of logical CPUs

Psutil.cpu_count (Logical=false) gets The number of physical CPUs

Display disk information:

Psutil.disk_usage ('/') disk usage

Psutil.disk_partitions () disk partitioning situation

Psuti.disk_io_counter () show total io

Psutil.disk_io_counter (perdisk=true) gets the number of IO for a single partition

Display Network information:

Psutil.net_io_counters () receive send bytes and other information

Psutil.net_io_counters (pernic=true) IO information for each network Oh interface

Show additional information:

Psutil.users () displays the currently logged on user

Psutil.boot_time () shows how long the boot has been

Get system Process Management methods

Psutil.process ()

Psutil.pids ()

p = psutil. Processes ( process numbers ) instantiate a process object with parameters

P.name () process name

P.exe () process bin Path

Absolute path of the P.CWD () process working directory

P.status () process State

P.create_time () process creation time, timestamp format

P.uids () process UID

P.gids () process GID

P.cpu_times () process CPU time includes USER and SYSTEM two time

P.cpu_affinity () CPU affinity of the process

P.memory_percent () Process Memory Utilization

P.memory_info () process Memory RSS VMS Information

P.io_counters () process io information

P.connections ()
