捕捉运行超过30分钟的过程，并发送

Question

我写这是捕获操作系统上运行的“RM”过程中一个小码报告..下面是代码

bash-4.1$ cat CheckRM1.py 
#!/usr/bin/python 
import subprocess 

def Check_Ps(): 
    ps = subprocess.Popen(['ps', '-eo' 'pid,user,args,etime='], stdout=subprocess.PIPE) 
    output = ps.communicate()[0] 
    for line in output.splitlines(): 
     if 'rm' in line: 
      pss = (line) 
      print pss 

Check_Ps() 

When i run the code, it generate the output in the below form: this basically giving the process ID number(PID) , user name, command & at last the total time since the process running. This time basically uses the format [[dd-]hh:]mm:ss . In my case its running more than 9 mins.

bash-4.1$ ./CheckRM1.py 
22908 karn  rm -i e ee q r w     09:19 

现在我正在寻找运行更多30分钟的过程，并将其打印出来并发送邮件。因此，任何想法如何捕获只有超过30分钟的过程，将不胜感激。

注意：我正在使用python 2.7。

Question: ... how to capture only process running more than 30 mins

你已经接近，split(..由空格，例如线时间

import re 

time_str = line.split(' ')[-1] 
# format [[dd-]hh:]mm:ss 
time_items = [int(e) for e in re.split('[-:]', time_str)] 

dd = 0 
if len(time_items) == 2: 
    hh = 0 
    mm,ss = time_items 
elif len(time_items) == 3: 
    hh, mm, ss = time_items 
else: 
    dd,hh,mm,ss = time_items 

print('Process is running {} Days {} Hours {} Minutes {} Seconds'.format(dd,hh,mm,ss)) 

time_minutes = (hh*60) + mm 
if time_minutes >= 30: 
    # do report 

测试使用Python 3.4.2
