PowerShell script to keep BizTalk Application up and running

Recently there was a chance to implement the Power Shell script which will monitor the BizTalk application . It is very simple script which get executed by windows task scheduler at predefined time period. It will start all artifacts of BizTalk which will in stop/disable/unlisted state. If the artifacts are up and running, it will not do anything.

#BizTalk Application Monitoring
$Date = Get-Date
$Logfile = "C:ScriptLogs$(gc env:computername)_$(get-date -f yyyy-MM-dd).log"
Function LogWrite
{
   Param ([string]$logstring)
   Add-content $Logfile -value $logstring
}
$test = '----------------------------------------------------------'
LogWrite  $test
$test = 'Script Started-BizTalk Monitor at '+$Date.DateTime
LogWrite  $test

 # Get local BizTalk DBName and DB Server from WMI

 $btsSettings = get-wmiobject MSBTS_GroupSetting -namespace 'rootMicrosoftBizTalkServer'

 $dbInstance = $btsSettings.MgmtDbServerName

 $dbName = $btsSettings.MgmtDbName

 # Load BizTalk ExplorerOM

 [void] [System.reflection.Assembly]::LoadWithPartialName("Microsoft.BizTalk.ExplorerOM")

 $BizTalkOM = New-Object Microsoft.BizTalk.ExplorerOM.BtsCatalogExplorer

 $BizTalkOM.ConnectionString = "SERVER=$dbInstance;DATABASE=$dbName;Integrated Security=SSPI"

 [ARRAY]$apps=$BizTalkOM.Applications
  Foreach ($app in $apps)
    {
       if ($app.Name -like 'BizTalkAppName*')
        {
         $app.Start(63)
         $BizTalkOM.SaveChanges()
     
         $test = $app.Name+ " Started"
         LogWrite  $test
       }

    }
 $test = 'Script executed sucessfully at '+$Date.DateTime
 LogWrite  $test

 $test = '----------------------------------------------------------'
 LogWrite  $test
