Question

我创建了以下脚本，该脚本提供了为Linux系统定义的文件系统用法。我已经设置了阈值来检查状态，如果它超过了它的简单说FS超过90％并且工作正常。因此，无论是在90或100的阈值之后，它只是简单地说it's more than 90%。

现在我唯一期待把它从if条件中得到的实际值放在一边，不知怎的，我现在无法得到它。所以，试着去了解How to get the value of if condition and store in a variable in python。感谢您对此脚本或脚本的任何更改提供任何帮助。

import subprocess
import socket
threshold = 90
hst_name = (socket.gethostname())

def fs_function(usage):
   return_val = None
   try:
      return_val = subprocess.Popen(['df', '-Ph', usage], stdout=subprocess.PIPE)
   except IndexError:
      print "Mount point not found."
   return return_val

def show_result(output, mount_name):
   if len(output) > 0:
      for x in output[1:]:
         if int(x.split()[-2][:-1]) >= threshold:
            print "Service Status:  Filesystem For " + mount_name + " is not normal & it's more than " + str(threshold) + "% on the host",hst_name
         else:
            print "Service Status:  Filesystem For " + mount_name + " is normal on the host",hst_name


def fs_main():
   rootfs = fs_function("/")
   varfs  = fs_function("/var")
   tmPfs = fs_function("/tmp")

   output = rootfs.communicate()[0].strip().split("\n")
   show_result(output, "root (/)")

   output = varfs.communicate()[0].strip().split("\n")
   show_result(output, "Var (/var)")

   output = tmPfs.communicate()[0].strip().split("\n")
   show_result(output, "tmp (/tmp)")
fs_main()

上面的脚本给出了如下输出：

Service Status:  Filesystem For root (/) is not normal & it's more than 90% on the host noi-karn
Service Status:  Filesystem For Var (/var) is normal on the host noi-karn
Service Status:  Filesystem For tmp (/tmp) is normal on the host noi-karn

只需将import psutil status_normal = "normal" status_abnormal = "not normal & it's more than {}%".format(threshold) for partition in psutil.disk_partitions(): usage = psutil.disk_usage(partition.mountpoint) status = status_abnormal if usage.percent > threshold else status_normal print "Filesystem For {} is {} on the host {}".format( partition.mountpoint, status, hst_name)表达式的结果放入变量中：

x/ (1024.0 * 1024.0 * 1024.0)

你可能想避免重新发明轮子;优秀的psutil project支持读取磁盘统计信息：

x/ (1024D * 1024D * 1024D)
