a Windows PowerShell Script used to monitor an Android process' CPU/Mem info

for used on Android
不过Android各个版本之间格式输出差异较大，需要依据具体格式调整

脚本可监控Android平台上某个应用的系统资源使用率，包括CPU，物理内存PSS，总堆内存Heap，Dalvik虚拟机堆内存。Heap和Dalvik之差即为jni的堆内存消耗。

使用之前先保证PC上adb环境可用，Android手机的驱动也安装了
然后用adb shell ps找到需要监控的应用进程，及对应的进程号processID

# define the process id that want to be monitored
$processId = "278"
# define the time interval for data collection, in seconds.
$timeInterval = 2
# define the continuous running hours.
# generally should be 24, that's for 1 day; or 72, for 3 days
# if need to take a test, set it as 5/3600, which means 5 seconds
$rHours = 2/3600

# define output data folder path, note there must be a "\" after disk & path
$disk = "C:\"
$path = "logs\"
$folder = $disk+$path

# DO NOT CHANGE BELOW IF NO NEED

# create output data folder if not exist
if (test-path $folder){echo "$folder already exit"}
else {new-item -path $disk -name $path -type directory}

# got output data file name
$ymd = get-date -format "yyyyMMdd"
$fname="monitor_"+$ymd
$fname=$fname+"_"+$processid+".log"
$outfile = "$folder"+$fname
# got Sample number according to running hours
$SampleNumber = $rHours*3600/$timeInterval

echo "********************************************"
echo "      Begin collecting data..."
echo "pid is $processid"
echo "time interval is every $timeInterval seconds"
echo "plan running for $rHours hours"

echo " Total_Heap(KB) java_Heap(KB) pss(KB) CPU(%)" > $outfile

for ($i=0;$i -le $SampleNumber; $i++)
{
$d_time = get-date -format "HH:mm:ss"

$m_Dal = adb shell dumpsys meminfo $processId | select-string "Dalvik" | Out-String
$m_Dal = $m_Dal.trim() -replace "\s{2,}" ," "
$m_Dal = $m_Dal.split(" ")[-3]

$cpu = $cpu.split(" ")[0]

# Note: for Powershell version below 5.1, tee-object -Append not supported!
