终于用PYTHON作了一个实用于工作的脚本啦----通过邮件定时发送服务器空闲空间

呵呵，GOOGLE上东拼西凑的东东。找了十来个综合，裁剪成一个。

没有风格，不正规，无注释，只是简单可以运行。PYTHON2.4以上通上。

代码：

 1 #!/usr/bin/env python
 2 # -*- encoding: utf-8 -*-
 3
 4 import os, socket, statvfs
 5 from time import localtime, strftime
 6 from smtplib import SMTP
 7
 8 smtp = SMTP()
 9 #smtp.set_debuglevel(debuglevel)
10 smtp.connect('1.2.3.4', 25)
11 smtp.login('user', 'pass')
12
13 from_addr = "alert<alert@freedisk.com>"
14 to_addr = ["ag@163.com","ae@163.com","af@163.com"]
15
16 # Limit in MiB
17 LIMIT=200000;
18
19 #Define current Time as Fri, 04 Mar 2011 08:47:10
20 TIME = strftime("%d %b %Y", localtime())
21
22 MONITOR = os.statvfs("/")
23 SPACE_LEFT=(MONITOR.f_bavail * MONITOR.f_frsize) / 1048576
24 SPACE_TOTAL = (MONITOR.f_blocks * MONITOR.f_frsize) / 1048576
25
26 if (SPACE_LEFT < LIMIT):
27     STATUS = "Free Disk Space is ALERT!!!ALERT!!!ALERT!!! "
28         SPACE_LEFT=SPACE_LEFT / 1024 #GiB
29         print ( TIME+"\n"+STATUS+"\n"+str(SPACE_LEFT)+" GB left on disk\n"+"Alert Space is:"+str((LIMIT/1024))+"GB")
30         subj = "ALERT!!!ALERT!!!ALERT!!!["+str(SPACE_LEFT)+" GB left]Free disk space on www.163.com "+TIME
31         message_text = TIME+"\n"+STATUS+"\n"+str(SPACE_LEFT)+" GB left on disk\n"+"Alert Space is:"+str((LIMIT/1024))+"GB"
32         msg = "From: %s\nTo: %s\nSubject: %s\nDate: %s\n\n%s" % ( from_addr, to_addr, subj, TIME, message_text )
33         smtp.sendmail(from_addr, to_addr, msg)
34     smtp.sendmail(from_addr, to_addr, msg)
35     smtp.sendmail(from_addr, to_addr, msg)
36         smtp.quit()
37         print ('Done')
38
39 elif (SPACE_LEFT > LIMIT):
40         STATUS = "Free Disk Space is OK on "
41            SPACE_LEFT=SPACE_LEFT / 1024 #GiB
42     SPACE_TOTAL=SPACE_TOTAL / 1024 #GB
43         print ( TIME+"\n"+STATUS+"\n"+str(SPACE_LEFT)+" GB left on disk("+str(SPACE_TOTAL)+"GB)\n"+"Alert Space is:"+str((LIMIT/1024))+"GB")
44     subj = "["+str(SPACE_LEFT)+" GB left]Free disk space on www.163.com "+TIME
45         message_text = TIME+"\n"+STATUS+"\n"+"Total space is :"+str(SPACE_TOTAL)+"GB\n"+str(SPACE_LEFT)+" GB left on disk\n"+"Alert Space is:"+str((LIMIT/1024))+"GB"
46         msg = "From: %s\nTo: %s\nSubject: %s\nDate: %s\n\n%s" % ( from_addr, to_addr, subj, TIME, message_text )
47         smtp.sendmail(from_addr, to_addr, msg)
48         smtp.quit()
49         print ('Done!')
50
51 else:
52         print ("""
53 A serius problem detected with the script.
54 Please check what mount points you monitor and check that they're in the MON_ARRAY aswell.
55 """ )

然后，将其放入/etc/spool/cron/相关用户文件里。
