applicationinsights-snapshotcollector's Issues

Unable to log snapshots from .NET 6 console app

The application successfully logs errors and messages to Application Insights but not debug snapshots. No options for snapshots appear in Azure.

When attempting to create a support request in Azure, it runs a diagnostic test that says snapshots were not sent:

Our diagnostic has detected that the configured application(s) have not sent any data to the Application Insights resource with name ApplicationInsightsinstance and instrumentation key XYZ between 11/2/2022 5:00 PM and 11/3/2022 5:00 PM. This is an indication that there is a configuration issue with your application and you should follow the troubleshooting steps below to correct your issue.

SnapshotUploader.exe is not found anywhere on the dev machine. The local temp folders configured below had to be created manually and remain empty.

Configuration:

• See dialedin2014/ApplicationInsightsTest: AI experiment (github.com)
• .NET 6 Console app using the Generic Host
• services.AddSnapshotCollector() called
• Using the latest Microsoft.ApplicationInsights.WorkerService package
• Using the latest Microsoft.ApplicationInsights.SnapshotCollector package
• SnapshotCollectorConfiguration ShadowCopyFolder is set to C:\temp\SnapshotUploader
• Using the ServerTelemetryChannel configured with StorageFolder = @"C:\temp\aisdkstorage"
• Viewing results in Azure under ApplicationInsightsinstance | Failures as a user with the Application Insights Snapshot Debugger in that instance
• The test throws a new InvalidOperationException twice with the same message to meet ThresholdForSnapshotting
• The Azure region is not Azure Government or Azure China

What is missing?

Missing "Open Debug Trace" button for Snapshot Debugger

I am Long from Office division.
My team is exploring Snapshot Debugger. I tried to install it, but cannot download the snapshot. The button "Open Debug Trace" is missing my portal.
Target: I want to download the snapshot

My stack: Appservice for Windows, Net6
I installed these 2 Nugets: "Microsoft.ApplicationInsights.AspNetCore" Version="2.20.0" , "Microsoft.ApplicationInsights.SnapshotCollector" Version="1.4.2"

I have services.AddSnapshotCollector((configuration) => Configuration.Bind(nameof(SnapshotCollectorConfiguration), configuration)); in Startup.cs

I could get exception logged to Application Insights, so I dont have problem with AAD auth.
My settings are followed:

Missing button:

Suspended processes causing low virtual memory

We are using default snapshot collector configuration in an Asp.net MVC application targeting .net 4.8
Snapshot collector for dumps create a suspended w3wp process which is not getting killed after the collections. causing low virtual memory on the server and sometimes the app pool stops due to that.

The issue is quite similar to the one in this blog https://www.codewrecks.com/blog/index.php/2019/07/03/application-insight-snapshot-debugger-and-strange-production-problem/

Here is the screenshot of suspended w3wp and low virtual memory warnings

How long it is expected that suspended w3wp will stay in memory ?

Snapshot Collector may not be able to find ShadowCopyFolder in .NET 6 single file executables

Observed this exception when trying to use snapshot collector (v1.4.3) with a program published as a single binary.

Event: ExceptionDuringNativeComponentExtraction

System.ArgumentException: The path is empty. (Parameter 'path')
at System.IO.Path.GetFullPath(String path)
at System.IO.FileInfo..ctor(String originalPath, String fullPath, String fileName, Boolean isNormalized) at

Can't get too much detail given the environment contraints but I'll see if I can get more info if needed.

Microsoft.Data.SqlClient.SqlConnection' threw an exception with SnapshotCollector 1.4.0 and 1.4.1

No issue with the version : 1.3.7.5 of Microsoft.ApplicationInsights.SnapshotCollector

Since the upgrade to 1.4.0 (and same error with 1.4.1)

When we call EF core call to the SQL DB we get this error message :

System.TypeInitializationException: 'The type initializer for 'Microsoft.Data.SqlClient.SqlConnection' threw an exception.'
ArgumentException: Delegates must be of the same type.

Thank you ! :-)

Dependency to deprecated package System.IO.FileSystem.AccessControl

The NuGet package of ApplicationInsights-SnapshotCollector has got a dependency to
System.IO.FileSystem.AccessControl (>=4.7.0).

System.IO.FileSystem.AccessControl is marked as deprecated.

Is there any planned solution or workaround for this issue?

Add Linux support

Please vote or add comments regarding support for Application Insights Snapshot Debugger for .NET Core application on Linux.

If you comment, it would help if you could describe the environment (e.g. in a Linux VM; in a docker container; in Kubernetes; in Azure App Service for Linux).

Exception on hostBuilder.Build()

Exception Info: System.AggregateException: One or more errors occurred. The semaphore has been disposed.

Not sure if this is the correct place but we have been seeing this more and more since April timeframe. Not sure what other info to provide so let me know if there is anything else we can try to add. Or please point us in the right direction if possible.

Thanks!!

Various potential bugs

The snapshot collector seems to work fine in production but we are having trouble in development/build since the snapshot collector is making a significant number of external calls that cannot route through a firewall.

Without the nuget package installed, everything runs as expected, the only app insights events I see in the debug log are what I expect using the correct iKey.

With the package installed, I see a significant number of events like these two:

Application Insights Telemetry: {"name":"AppEvents","time":"2021-09-30T09:20:56.8831014Z","iKey":"8a28de91-bcf6-44ac-9242-f7a64f1146b8","tags":{"ai.application.ver":"1.4.0.0","ai.device.osVersion":"Microsoft Windows 10.0.19043","ai.cloud.roleInstance":"/PU6k0iJgzHB","ai.session.id":"dYYeFjWs/Le7","ai.internal.sdkVersion":"dotnetc:2.18.0-315","ai.internal.nodeName":"DEV-01.smartsurvey.local"},"data":{"baseType":"EventData","baseData":{"ver":2,"name":"TelemetryProcessorCreated","properties":{"Runtime":".NET Core 3.1.19","TelemetryProcessor":"SnapshotCollectorTelemetryProcessor Problems:Count=0"}}}}

Application Insights Telemetry: {"name":"AppDependencies","time":"2021-09-30T09:20:56.8818670Z","iKey":"xxxxxxxx-xxxx-xxxx-xxxx-62d47594c409","tags":{"ai.application.ver":"15.0.0.0","ai.cloud.roleInstance":"DEV-01","ai.operation.id":"b7a8c124c63ab14db3955c8083467fce","ai.internal.sdkVersion":"rdddsc:2.18.0-315","ai.internal.nodeName":"DEV-01.ss.local"},"data":{"baseType":"RemoteDependencyData","baseData":{"ver":2,"name":"GET /metadata/instance/compute","id":"b2d10a6620b6864d","data":"http://169.254.169.254/metadata/instance/compute?api-version=2017-08-01","duration":"00:00:00.3702150","resultCode":"Canceled","success":false,"type":"Http","target":"169.254.169.254","properties":{"AspNetCoreEnvironment":"Development","DeveloperMode":"true","_MS.ProcessedByMetricExtractors":"(Name:'Dependencies', Ver:'1.1')"}}}}

Note that the first one has an incorrect iKey, which I cannot find anywhere in my code or on github. The second has the correct key, which I have masked. The second one is occuring "correctly" in that the snapshot collector is calling out to http://169.254.169.254/metadata/instance/compute, whatever that is.

I then tried to set IsEnabled to false in appsettings and it didn't disable these calls.

"SnapshotCollectorConfiguration": {
    "IsEnabled": false,
    "IsEnabledInDeveloperMode": false
  } 

Note that we are not hosting these on Azure App Service and don't have any App Services running for any of our apps, which I am mentioning because the first refers to a roleinstance and the second to metadata/instance, which I believe is a cloud service endpoint for local metrics data.

AppInsight Snapshot Debbugger Doesn't show locals vars

I've installed and configured appinsight in my template project with .NET 4.7.2

The AppInsight work fine, but the snapshot debbuger only shows call stack and decompiled code.

My sample exception code:

I've make sure that the pdb generated and it's in debug mode based on this link: Azure App Insights Debug Snapshot doesn't show Locals and Variables , also enable developer mode, but it doesn't work.

I've also added dependent assembly according to this link: Application Insight Snapshot Debugger: Snapshots are not being pushed from a .NET Full Framework Site

But it doesn't work. Please help. Thank you
