【摘要】

實(shí)時(shí)掌握服務(wù)器運(yùn)行狀態(tài)對(duì)系統(tǒng)管理員來(lái)說(shuō)非常重要，服務(wù)器出現(xiàn)問(wèn)題是第一時(shí)間知道可以保證及時(shí)處理，將意外損失降到最小。利用powershell可簡(jiǎn)單實(shí)現(xiàn)監(jiān)控功能，并在服務(wù)器掉線(xiàn)或關(guān)鍵服務(wù)停止時(shí)發(fā)出郵件通知管理員，使管理員可以及時(shí)處理故障。

【正文】

一   腳本組成

如圖，除powershell腳本文件外，需要?jiǎng)?chuàng)建3個(gè)txt文件，分別為Servers.txt、Services.txt、Urls.txt。三個(gè)文件都是以csv格式導(dǎo)入，第一行內(nèi)容需要保留，添加內(nèi)容由第二行開(kāi)始

Servers.txt添加服務(wù)器名用于監(jiān)控服務(wù)器在線(xiàn)情況

Services.txt添加服務(wù)器名及服務(wù)名用于監(jiān)控關(guān)鍵服務(wù)運(yùn)行情況

Urls.txt添加網(wǎng)站用于監(jiān)控網(wǎng)頁(yè)是否能正常打開(kāi)

二   腳本內(nèi)容

$Urls = import-csv Urls.txt

$Servers = import-csv Servers.txt

$Services = import-csv Services.txt

$mailcontent = $null

$mailFrom = "XXX@canway.net"

$mailTo = "XXX@canway.net"

$Credential = Get-Credential -Credential $mailFrom

While($true)

{

Foreach ($server in $Servers)

{

$hostname = $server.server

if (!(test-connection $hostname -count 2 -quiet))

{$date = Get-Date

 $mailcontent = $mailcontent + "$hostname is offline $date `n"

 Write-Host "$hostname is offline $date" -ForegroundColor Red}

}

Foreach ($service in $Services)

{

$Server = $Service.server

$ServiceName = $Service.service

If (!(test-connection $Server -count 2 -quiet))

{$date = Get-Date

 $mailcontent = $mailcontent + "$Server is offline $date `n"

 Write-Host "$Server is offline $date" -ForegroundColor Red}

 Else

{$Servicestate = (Get-WmiObject -Class win32_service -ComputerName $Server|Where-Object{$_.Name -eq $ServiceName}).State

If($Servicestate -ne "Running")

{$date = Get-Date

 $mailcontent = $mailcontent + "$ServiceName in $Server is not running! $date `n"

 Write-Host "$ServiceName in $Server is not running! $date" -ForegroundColor Red}

 }

}

Foreach($url in $Urls)

{

$Website = $url.website

Invoke-WebRequest $Website

If(!$?)

{$date = Get-Date

 $mailcontent = $mailcontent + "$Website 無(wú)法連接 $date `n"

 Write-Host "$Website 無(wú)法連接 $date" -ForegroundColor Red}

}

If($mailcontent -ne $null)

{

Send-MailMessage -Body $mailcontent -SmtpServer smtp.partner.outlook.cn -From $mailFrom -To $mailTo -Subject "Warning" -UseSsl -Credential $Credential -Port 587

}

$mailcontent = $null

sleep 3600

}

三   腳本使用

用1.2所列出的腳本內(nèi)容創(chuàng)建powershell腳本，與Servers.txt、Services.txt、Urls.txt放在同一路徑下，用有權(quán)限的賬戶(hù)運(yùn)行

當(dāng)有任意一項(xiàng)檢查不通過(guò)時(shí)，會(huì)發(fā)郵件通知管理員。如圖，修改以下位置可以自定義收件人和發(fā)件人。

       運(yùn)行腳本后會(huì)讓你填入郵箱密碼，之后腳本就會(huì)每個(gè)小時(shí)檢查一次，檢查不通過(guò)時(shí)發(fā)郵件到設(shè)定的收件人，腳本檢查間隔可自定義，如圖，初始設(shè)置為3600s

收到郵件如圖

選擇發(fā)件人郵箱后需要在下面的命令里修改Smtp服務(wù)器和端口號(hào)

Send-MailMessage -Body $mailcontent -SmtpServer smtp.partner.outlook.cn -From $mailFrom -To $mailTo -Subject"Warning" -UseSsl -Credential $Credential -Port 587
