【python】获取实际内存数据pss--total

python通过adb命令获取实际内存数据

1.在执行代码前，需要确保能够在doc窗口执行adb命令，开始的数据可能会有问题（目前知识不够，以后再做更改）

#coding=utf-8
import time
import subprocess
import xlwt

package_name_mysdk = 'com.tcl.live'

def getPSS(package_name):
#用adb获取信息adb shell "dumpsys meminfo com.tcl.live | grep "TOTAL""
p = subprocess.Popen('adb shell "dumpsys meminfo ' + package_name + ' | grep "TOTAL""',stdout = subprocess.PIPE, stderr = subprocess.PIPE)
text = p.stdout.read()
listoftext = text.split()
print 'PSS=' + listoftext[1]
return int(listoftext[1])

time_start = 0
time_end = 0

#创建新的工作薄
book = xlwt.Workbook(encoding = 'utf-8', style_compression = 0)
#创建新的sheet,并命名为PSS
sheet_sdk = book.add_sheet('PSS-SDK', cell_overwrite_ok = True)
sheet_sdk.write(0, 0, "time")
sheet_sdk.write(0, 1, "PSS")

#excel表格的行（row）、列（col）
row = 1
col = 0

#测试时间为3600s=1h
while time_end <= 3600:
#获取当前时间
timeNow = time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(time.time()))
print timeNow
sheet_sdk.write(row, col, timeNow)
try:
pss_sdk = getPSS(package_name_mysdk)
sheet_sdk.write(row, col + 1, pss_sdk)
except:
print time.strftime('%Y-%m-%d  %H:%M:%S', time.localtime(time.time())) +"process has been shuoutdown!"

row += 1
time_end += 1
#获取pss total值时间间隔10s
time.sleep(10)
book.save(r"d:\\pss.xls")

2.在D盘根目录找到pss.xls

对数据进行简单的修改和分析
