python3 输出系统信息
一、安装psutil库
pip3 install psutil
二、代码
#!/usr/bin/python3 coding=utf-8 import psutil import uuid import socket import os #系统与磁盘挂载 print('##########系统与磁盘信息#########') def get_mac_address(): mac=uuid.UUID(int = uuid.getnode()).hex[-12:] return ":".join([mac[e:e+2] for e in range(0,11,2)]) def get_host_ip(): try: s=socket.socket(socket.AF_INET,socket.SOCK_DGRAM) s.connect(('8.8.8.8',80)) ip=s.getsockname()[0] finally: s.close() return ip def get_load(): f = open("/proc/loadavg") loadstate=f.read().split() return loadstate load_list = get_load()[0:3] system_load = '' for i in load_list: if system_load: system_load = system_load+','+i else: system_load = i myname = socket.getfqdn(socket.gethostname()) print('主机名称:',myname) print('本机ip地址:',get_host_ip()) print('本机MAC地址:',get_mac_address()) print('系统负载(1,5,15分钟):',system_load) print('系统进程数:',len(psutil.pids())) devs = psutil.disk_partitions() for dev in devs: statvfs = os.statvfs(dev.mountpoint) devs = psutil.disk_partitions() for dev in devs: statvfs = os.statvfs(dev.mountpoint) total_disk_space = statvfs.f_frsize * statvfs.f_blocks free_disk_space = statvfs.f_frsize * statvfs.f_bfree disk_usage = int((total_disk_space - free_disk_space) * 100.0 / total_disk_space) print('挂在设备:%s,挂载点:%s 磁盘使用率:%d%% 文件系统:%s' % (dev.device,dev.mountpoint,disk_usage,dev.fstype)) #系统负载 def get_load(): f = open("/proc/loadavg") loadstate=f.read().split() return loadstate load_list = get_load()[0:3] system_load = '' for i in load_list: if system_load: system_load = system_load+','+i else: system_load = i print('系统负载(1,5,15分钟):',system_load) #cpu cts = psutil.cpu_times() cputime = 0 for item in cts: if item != 0: cputime = cputime + item print('########CPU信息#########') print('用户时间:%d%%' % (cts.user/cputime * 100)) print('内核时间:%d%%' % (cts.system/cputime * 100)) print('空闲时间:%d%%' % (cts.idle/cputime * 100)) print('逻辑CPU个数:',psutil.cpu_count()) print('物理cpu数量:',psutil.cpu_count(logical=False)) #内存 print('#########内存信息############') mem = psutil.virtual_memory() print('内存大小: %dM'%(int(mem.total/1024/1024))) print('已使用内存: %dM'%(int(mem.used/1000/1000))) print('剩余内存:%dM'%(int(mem.free/1024/1024))) print('内存使用率: %d%%'%(int(mem.percent)))
三、运行结果
