### **获取ip:** ###

value=socket.getaddrinfo(socket.gethostname(),None)#socket.gethostname()获取主机名 socket.getaddrinfo()获取ip
    for i in value:
        ip=i[4][0]
        if ip .find('192.')==0:
            print ip

### **获取某个硬盘的使用量：** ###

def getdisk():
        statvfs = os.statvfs('/data')
        total_disk_space = statvfs.f_frsize * statvfs.f_blocks   #f_frsize:分栈大小，f_blocks:文件系统数据块总数
        free_disk_space = statvfs.f_frsize * statvfs.f_bavail    #f_bavail:非超级用户可获取块数
        disk_usage = (total_disk_space - free_disk_space) * 100.0 / total_disk_space
        disk_usage = int(disk_usage)
        print disk_usage

### **获取CPU使用量：** ###

def getcpu():
        #sar -u 1 2 获取cpu详情 每一秒采样一次 连续采两次
        p = subprocess.Popen('sar -u 1 2', shell=True, stdout=subprocess.PIPE,stderr=subprocess.PIPE,)
        for i in  p.stdout.read().split('\n'):
            if i.find("Average")>=0:
                 print  100 - int(float(i.split(' ')[-1])+0.5)

### **获取内存剩余量：** ###

def getmem():
        with open('/proc/meminfo') as f:
            total = int(f.readline().split()[1])  #总物理内存大小
            free = int(f.readline().split()[1])   #可用还剩多少
            av=int(f.readline().split()[1])
            buffers = int(f.readline().split()[1]) #磁盘缓存大小
            cache = int(f.readline().split()[1]) # 磁盘缓存大小
        mem_use = total-free-buffers-cache
        print  mem_use*100/total #已用多少
