Logging Jobs with Start-Transcript
- Cortlandt _
Powershell (.ps1) scripts supports much better logging than SQL Server Agent or Windows Task Scheduler (WTS).
The Start-Transcript command captures script and program output at the script level. This level of logging catches error messages that other logging strategies miss. Logging features in application programs for instance don’t begin to capture error messages until sometime after the application program begins running.
In contrast the job logging in SQL Server Agent and WTS is very minimal.
Example of Logging with PowerShell Start-Transcript
######### Start Logging #########################################
$DateTimeStr = Get-Date -UFormat %Y-%m-%d@%H-%M # date-time string for log file name
[string]$RunLogsPath = "$($PSScriptRoot)\Run_Logs" # path for log file created below
[string]$Transcript_FileRef = "$($RunLogsPath)\RunLog_$DateTimeStr.txt"
Start-Transcript -Path $Transcript_FileRef -Append -Verbose Notes
$PSScriptRootreturns the full path of the executing script's parent directory.
$PSScriptRoot is used here as the ‘base’ path for a sub-folder named “\Run_Logs".$PSScriptRoot is a variables that stores state information for and about PowerShell scripts. These variables are created and maintained by PowerShell. https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_automatic_variables?view=powershell-7.2
