Powershell 将输出从三个命令减少到一行

我有这个剧本：

$counterWS = "\Process(powershell)\Working Set"
$counterWSPe = "\Process(powershell)\Working Set Peak" 
$counterWSPr = "\Process(powershell)\Working Set - Private"

$dataWS = Get-Counter -Counter $counterWS
$dataWSPe = Get-Counter -Counter $counterWSPe
$dataWSPr = Get-Counter -Counter $counterWSPr

$dataWS.countersamples | Format-Table Timestamp,@{Name='WorkingSet';Expression={($_.CookedValue/1KB)}},WorkingSetPeak,WorkingSetPrivate -Auto | findstr Timestamp
$dataWS.countersamples | Format-Table Timestamp,@{Name='WorkingSet';Expression={($_.CookedValue/1KB)}},WorkingSetPeak,WorkingSetPrivate -Auto | findstr [-]

while ($true) {
    $dataWS.countersamples | Format-Table Timestamp,@{Name='WorkingSet';Expression={($_.CookedValue/1KB)}},WorkingSetPeak,WorkingSetPrivate -Auto | findstr [:]
    $dataWSPe.countersamples | Format-Table Timestamp,WorkingSet,@{Name='WorkingSetPeak';Expression={($_.CookedValue/1KB)}},WorkingSetPrivate -Auto | findstr [:]
    $dataWSPr.countersamples | Format-Table Timestamp,WorkingSet,WorkingSetPeak,@{Name='WorkingSetPrivate';Expression={($_.CookedValue/1KB)}} -Auto | findstr [:]
    Start-Sleep -s $args[0]
}

结果是：

Timestamp WorkingSet WorkingSetPeak WorkingSetPrivate --------- ---------- -------------- ----------------- 29/07/2016 18:41:12 10644 29/07/2016 18:41:13 10676 29/07/2016 18:41:14 3056 时间戳工作集工作集峰值工作集专用 --------- ---------- -------------- ----------------- 29/07/2016 18:41:12 10644 29/07/2016 18:41:13 10676 29/07/2016 18:41:14 3056 有没有一种方法可以减少这样的输出：

Timestamp WorkingSet WorkingSetPeak WorkingSetPrivate --------- ---------- -------------- ----------------- 29/07/2016 18:41:12 10644 10676 3056

@{n='WorkingSetPeak';e={
  ($_.CounterSamples | Where-Object { $_.Path -like '*peak' }).CookedValue / 1KB
}}

时间戳工作集工作集峰值工作集专用 --------- ---------- -------------- -----------------

---

2016年7月29日18:41:12 10644 10676 3056一次收集所有3个计数器（参数

-Counter

接受参数列表），然后将结果拆分为单独的：

CounterSamples

属性是可以通过索引单独访问的对象列表

如果您不想依赖按照传递给

Get Counter

的参数顺序返回的结果，您可以通过它们的路径选择它们，例如如下所示：

Timestamp WorkingSet WorkingSetPeak WorkingSetPrivate --------- ---------- -------------- ----------------- 29/07/2016 18:41:12 10644 10676 3056

@{n='WorkingSetPeak';e={
  ($_.CounterSamples | Where-Object { $_.Path -like '*peak' }).CookedValue / 1KB
}}

对于连续样本采集，将参数

-continuous

和

-SampleInterval

添加到

获取计数器

。不需要循环

$interval = 5  # seconds

Get-Counter -Counter $ws, $wsPeak, $wsPriv -Continuous -SampleInterval $interval |
    Select-Object ...
