Question

The title says it all.

Sitecore 9.0.1.

I've looked in the App_Data/logs and temp folders (the temp/__upgrade folder is not present).

I know the installationLog.txt file is going somewhere... But WHERE?

There are likely additional places and methods for retrieving this data, but the following is typically what I resort to:

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 Monitoring section

Turn Application Logging (Filesystem) On

Change Level to Verbose

Save

App Service Logs

Select Log stream from Monitoring section

Select Application logs

Log stream

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.

Kudu

From the App Service blade you used previously, select Advanced Tools from the Development Tools section.

Kudu access

Then press Go -> to open Kudu in a separate window

From the new window select Debug console > PowerShell

Kudu PowerShell

Next, drill down into Log Files/Application to view historically captured log files

By selecting 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.

Application logs

temp__upgrade Location

From Kudu, you can also drill down into that particular folder:

sitewwwroottemp

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).

The first approach works well for watching logs, but unfortunately the update installation wizard logs don't show up there. Also unfortunately, Kudu's consoles do not show all the files because they open in a sandboxed version. sad trombone — 5 hours ago

The files are stored in the temp folder, which is defined by a variable in the configs:

<sc.variable name="tempFolder" value="d:localtemp"/>

Unfortunately, browsing this folder with Kudu does not show the files in question because Kudu provisions a sandbox environment which does not contain the files.

Using Vlad's answer on a similar topic as a starting point, I was able to write up a simple temp folder browser which generates links to the files through the Sitecore.TempRequestHandler (Sitecore.Resources.TempRequestHandler, Sitecore.Kernel).

Throw this in an .aspx page in your /sitecore/admin folder to use it.
