Cannot configure sink using `APPINSIGHTS_CONNECTIONSTRING` without relying on `TelemetryClient` service

[batizar]

Hi, it is recommended in Microsoft docs to use Application Insights connection string over instrumentation key but when adding application insights with that sink will not submit any logs or metrics to Application Insights, when I switch back to using instrumentation key it will start working again.

Thanks.

Hi, anybody?!

Because of this issue I had to delete this package and use AI directly:

services.AddApplicationInsightsTelemetry(options => options.ConnectionString = s);

Also:

New Azure regions require the use of connection strings instead of instrumentation keys.

You need to manually initialize the Telemetry Configuration:

.WriteTo.ApplicationInsights(CreateAppInsightsTelemetryConfiguration(), new TraceTelemetryConverter(), LogEventLevel.Information)

Unfortunately, this does not work via appsettings.json based configuration because static methods are only called for interface or abstract type parameters.

Sorry about the delay. Hoping to help catch up on the backlog, here - #168 is tracking.

Any updates on this? Instrumentation key-based ingestion has now a deprecation date set https://azure.microsoft.com/en-us/updates/technical-support-for-instrumentation-key-based-global-ingestion-in-application-insights-will-end-on-31-march-2025/

@shahiddev is this one you'd be interested in shepherding through?

[shahiddev]

Hey @nblumhardt I can try and take a look - aware of the deprecation but wasn't aware of new regions not allowing connection strings

[nblumhardt]

Awesome :-)

@augustoproiete, I'm not 100% across what you have in mind for team structure, but I've invited @shahiddev to the org with maintainer rights in this repo. Drop me a line if there's a particular setup you had in mind.

Let me know if I can help get the ball rolling on anything :-)

Is there any news on this?

[nblumhardt]

Using:

.WriteTo.ApplicationInsights(services.GetRequiredService<TelemetryConfiguration>(), TelemetryConverter.Traces))

should work around this successfully, and is currently the suggested method of configuration. Can anyone please confirm?

[sebader]

@nblumhardt this does not work when you need to initialize the logger earlier than in the Startup.cs/ConfigureServices already

[nblumhardt]

@sebader gotcha! So the title of this issue should be something more like Cannot configure sink using APPINSIGHTS_CONNECTIONSTRING without relying on TelemetryClient service? Thanks 👍

It seems like adding a connection string option to the service configuration should be pretty straightforward, is anyone able to help out/take a shot at it?
