Note: I have not tested SPECIFICALLY for UpdateInstallationWizard logs
- In Azure Portal, select the App Service resource that you used to run the installation.
- Scroll down the blade and find
App Service logs in the
Application Logging (Filesystem) On
Level to Verbose
Log stream from
At this point, you will need to rerun the installation to capture new logs. Via
Log stream you can view the current output of logs. If you wish to view historical logs (if you've previously configured this)- then you'll need to use Kudu.
- From the App Service blade you used previously, select
Advanced Tools from the
Development Tools section.
- Then press
Go -> to open Kudu in a separate window
- From the new window select
Debug console >
- Next, drill down into
Log Files/Application to view historically captured log files
Verbose previously, the log files will contain all messages. At this point, it's a matter of searching the log file for messages related to your installation.
From Kudu, you can also drill down into that particular folder:
Though I cannot confirm that the expected files will appear there as the instance I'm referencing does not have them (though it has many other expected temp files).
