我为了监控系统性能，用 top -c -b -d 30 -n 600 > test 这样抓了一堆信息。
现在我想提取出当cpu > 80% 是进程的信息

但我的程序写出来有点问题...只能抓取到某一行而不是整块的信息。
请问大家该如何实现我的功能
import re
import subprocess
import sys
F=open(sys.argv[1])
value=0
L=[]
for i in subprocess.Popen('grep -w top -A 15 %s' %sys.argv[1],shell=True,stdout=subprocess.PIPE).stdout.readlines():
if re.findall(r'\d+\%us',i):
if int(re.findall(r'\d+',re.findall(r'\d+\.\d+%us',i)[0])[0]) > 23:
print i
这样写我只能抓到以下信息，而不是一整块的！
Cpu(s): 26.2%us, 13.1%sy, 3.1%ni, 56.1%id, 0.0%wa, 0.0%hi, 1.6%si, 0.0%st
Um....我自己写出来了！ 不过大家看看有没有其他更好的方法！
#!/usr/bin/env python
import re
import subprocess
import sys
F=open(sys.argv[1])
value=0
L=[]
for i in subprocess.Popen('grep -w top -A 15 %s' %sys.argv[1],shell=True,stdout=subprocess.PIPE).stdout.readlines():
if re.findall(r'\d+\%us',i):
if int(re.findall(r'\d+',re.findall(r'\d+\.\d+%us',i)[0])[0]) >= 75:
print subprocess.Popen('grep %s -A 15 -B 5 %s' %(i.split()[1],sys.argv[1]),shell=True,stdout=subprocess.PIPE).stdout.read()
恩...还是有点小问题！
这个程序读取处理的数据不是顺序排放的！
比如我文本的数据时1，2，3，4
读取出来的时候是1,4,3,2 是个乱序的！ 这个怎么解决？
import re
def getProcesses(usage=80.0, filename='performance.txt'):
with open(filename) as f:
lines = f.readlines()
for line in lines:
m = re.search('^\d+.*\s+(\d+\.\d+)\s+(\d+\.\d+).*\:', line)
if m:
cpu_usage = m.group(1)
if float(cpu_usage) > usage:
print "CPU: ", cpu_usage
print line
getProcesses()将序号和处理的文本放到一个元组里面，然后将元组存储到列表中，再按元组中的序号排列。
试试？
