App Insights Status Monitor Extension Failing to deploy with ARM template

Question

I just started getting this failure, not sure why; it was working fine yesterday. I only changed the appsettings and connectionstrings to be part or resources instead of the webapp to move the dependsOn down the chain. Previously, the site was dependsOn the dependencies for app settings and connection strings. Here is the ARM template for the website resource.

                "properties": {}
            }
        ]
    }

And the error I'm getting...

        "message": "The resource operation completed with terminal provisioning state 'Canceled'."
    }
}

Even with the error, it actually did install the extension correctly. During another test, it installed the extension, but when I opened it, the App Insights Profiler web job was not installed. Either way, not sure why there is a conflict. When I open the log in Kudu, there is pretty much nothing inside.

7/14/2017 2:44:39 PM: [Verbose] No web.config detected. The web app may be empty. Assume classic ASP.NET by default.

That's the entirety of the log.

On a previous test...

Same start of the file, but there are more entries. There is definitely a web config and the app is working so not sure what that's about.

7/13/2017 6:15:50 PM: [Verbose] Application is not instrumented with Application Insights.

The app is definitely instrumented and uses version 2.4 which is newer than 2.3 which was installed.

Answer 1

There seems to be no way to make the extension wait on app setting update so I moved the installation of the extension into a different task in the release environment. Now I have three tasks:

1.  ARM deploy common resources
2.  ARM deploy app dependencies and app service
3.  ARM deploy status monitor site extension
4.  Web Deploy code into app service

However, in order to do this, you have to still specify the website somehow in step 3.

Here is what I did using the output from step 2 which has the webAppName, I had to specify the site again and then place the extension into the resources for that site. You must be careful about what you specify here as to not disrupt the previous deployment.
