Monitoring Server Status

Get System Performance Information

1, CPU information:

The Linux operating system uses several parts of the CPU:

User time; SystemTime; Wait Io;idle

Psutil.cpu_times ()

Psutil.cpu_times (). User

Psutil.cpu_count ()

2 , Memory information

psutil.virtual_memory () # View memory Full information

psutil.swap_memory () # View Swap Partition Information

3 , disk information

psutil.disk_io_counters () # get the hard drive IO Total

psutil.disk_usage ('/') # get the usage of a partition

psutil.disk_io_counters (perdisk=true) # gets a single partition of the IO number

4 , Network information

Psutil.net_io_counters # View the total network IO number

5 , other information

psutil.users () # View currently working with users

psutil.boot_time () # View current boot time

Datetime.datetime.fromtimestamp (Psutil.boot_time ()). Strftime ("%y-%m-%d%h:%m:%s") # Use datetime module Format time stamp

System Process Management methods:

1. Process Information

p = psutil. Process ID # instantiates a process object,

p.name () # Process Name

P.exe () # Process bin Path

p.cwd () # absolute path to the process directory

p.status () # process Status

p.create_time () # Process creation Time

p.uids () # Process UID Information

p.gids () # Process GID Information

2 , address processing module IPy

through version () method distinguishes IP address is IP4 or IP6 type

Example: IP (' 8.8.8.8 '). Version ()

outputs all of the network segments IP Address:

Ip=ip (' 192.168.118.0/24 ')

For x in IP:

Print (x)

customizing network segments for different output types , Output Type is string

Ip=ip (' 192.168.118.0/24 ')

ip.strnormal (0) no return, as 192.168.118.0

ip.strnormal (1) Prefix format, such as 192.168.118.0/24 ;

Ip.strnormal (2), Decimalnetmaskt format, such as 192.168.118.0/255.255.255.0

Ip.strnormal (3), Lastip format, such as 192.168.1.0-192.168.118.255

Network Information detection method:

judging the input IP or subnet back to network, mask, broadcast, ECHO resolution, number of subnets, and IP types and other information

#!/bin/env python From IPy import IP Ips=input (' Please input IP address\n ') Ip=ip (IPS) if (Ip.len () >1): Print (' Net:%s '% ip.net ()); Print (' netmask:%s '% ip.netmask ()) Print (' Broadcast:%s '% ip.broadcast ()) Print (' Reverse address%s '% ip.reversenames () [0]) Print (' Subnet:%s '% Ip.len ()) Else Print (' Reverse address%s '% ip.reversenames ()); Print (' heaxdemical:%s '% Ip.strhex ()); Print (' Binary IP:%s '% ip.strbin ()); Print (' Iptype:%s '% ip.iptype ());

Dnspython module resolution domain name

A Record

#!/usr/bin/env python From DNS import resolver domain=input (' Please input your domain name:\n ') # Please enter the domain name address a=resolver.query (domain, ' A ') # Specifies the type of A Record For I in A.response.answer: For J in I.items: Print (j.address)

MX Record

#!/usr/bin/env  python from  dns Import Resolver domain  = input (' Please input domain name: ') MX  = resolver.query (domain, ' MX ') for  i in MX:          print (' MX preference:   ', i.preference, ' Mail exchange: ', I.exchange)

NS Record

#!/usr/bin/env python From DNS import resolver Domain = input (' pelase input you domain name: ') NS = resolver.query (domain, ' NS ') For I in NS.response.answer: For J in I.items: Print (J.to_text ())

CNAME Record

#!/usr/bin/env python From DNS import resolver Domain = input (' pelase input you domain name: ') NS = resolver.query (domain, ' NS ') For I in NS.response.answer: For J in I.items: Print (J.to_text ())
