Extension logs

The extension sends logs to Azure about extension events.

The extension log file is at:

C:\ProgramData\GuestConfig\extension_logs\Microsoft.AzureData.WindowsAgent.SqlServer\

The log file name depends on the version Azure Extension for SQL Server, for the latest version of Azure Extension for SQL Server, the log file is:

unifiedagent.log

For extension version 1.1.24724.69 and earlier, the log file is:

ExtensionLog_0.log
