以下PowerShell腳本在重新啓動後監視服務器列表,並在它可以附加到Get-Service後立即通知服務器。PowerShell腳本的實時表格輸出
#start all jobs here
get-job | stop-job
get-job | remove-job
$servers = ("localhost", "127.0.0.1", "badserver")
function Ping-Service($myservers,[int]$timeout=60, [int]$waitbetweentrys=1){
$myservers| %{
$computername = $_
start-job -scriptblock {
param(
[string]$computername,
[int]$maxwait,
[int]$waitbetween
)
$status = "Fail"
$StartTime = Get-Date
$duration = 0
do
{
#if successful, break out
try {$gs = Get-Service -ComputerName $computername -ErrorAction Stop;$status = "Success";break} catch {start-sleep $waitbetween}
$duration = (New-TimeSpan $StartTime $(Get-Date)).Seconds
} while ($duration -lt $maxwait)
$hash = [ordered]@{"Computername" = $computername; "Type" = "Service";"Status"=$status;"Done"=$(Get-Date);"Duration"=$duration}
$hash
} -ArgumentList ($computername, $timeout, $waitbetweentrys)
}
}
Ping-Service -myservers $servers -timeout 10
#loops through jobs and check for completed ones
do
{
#process jobs that are done
$jobsdone = Get-Job | where State -eq 'Completed'
$joboutput = $jobsdone | Receive-Job
$joboutput | %{New-Object PSObject -Property $_ } |ft -AutoSize
#remove jobs once we get the output
$jobsdone | Remove-job
#See if there are any jobs left
$jobsleft = Get-Job
#wait 5 seconds before checking jobs
if ($jobsleft -ne $null) {start-sleep 5}
} while ($jobsleft -ne $null) #continue loop while there are jobs left
它運作良好,但輸出不格式化我怎麼會喜歡它:
Duration Status Computername Done Type
-------- ------ ------------ ---- ----
0 Success localhost 5/7/2013 4:09:30 PM Service
Duration Status Computername Done Type
-------- ------ ------------ ---- ----
0 Success 127.0.0.1 5/7/2013 4:09:31 PM Service
Duration Status Computername Done Type
-------- ------ ------------ ---- ----
10 Fail badserver 5/7/2013 4:09:42 PM Service
我想它看起來就像這樣:
Duration Status Computername Done Type
-------- ------ ------------ ---- ----
0 Success localhost 5/7/2013 4:09:30 PM Service
0 Success 127.0.0.1 5/7/2013 4:09:31 PM Service
10 Fail badserver 5/7/2013 4:09:42 PM Service
但是,關鍵是要實時顯示每個結果。具有諷刺意味的是,腳本頂部的開始輸出正是我想要的。
我想加在一起所有的輸出爲對象,所以我可以將該值傳遞給另一個腳本。如果我按照你的建議修改輸出,它將輸出一個帶有兩列的列表視圖。 – user2359792 2013-05-08 14:01:33
我沒有看到問題。樣本是否不完整(在其他地方是否使用了$ jobsdone)?如果是這樣,請使用我答案的第一部分來僅修復可見輸出。我刪除的唯一東西是不必要的對象創建和'format-table'(BY THE WAY,銷燬你剛剛創建的對象)。 – 2013-05-08 16:02:28
只是爲了澄清更多。如果將代碼保存爲腳本並運行它,它將返回對象的ARRAY,您可以將其存儲和/或傳遞給另一個cmdlet/function/script。因此,如果默認視圖是列表視圖,請運行'myscript.ps1 |「之類的東西format-table -autosize'。只記得不要在代碼中使用'format -...'cmdlet,因爲它返回一個特殊的formatobject,而不是原始的數據對象本身。 – 2013-05-08 18:02:10
