Setting up Cloud Trace for C# ASP.NET Core

You can enable Trace for ASP.NET Core applications by using the Google.Cloud.Diagnostics libraries for .NET.

Configure your platform

You can use Cloud Trace on Google Cloud and other platforms.

Running on Google Cloud

When your application is running on Google Cloud, you don't need to provide authentication credentials in the form of a service account to the client library. However, you do need to ensure that your Google Cloud platform has the Cloud Trace API access scope enabled.

For a list of supported Google Cloud environments, see Environment support.

For the following configurations, the default access-scope settings enable the Cloud Trace API:

If you use custom access scopes, then you must ensure that Cloud Trace API access scope is enabled:

  • For information about how to configure the access scopes for your environment by using the Google Cloud console, see Configuring your Google Cloud project.

  • For gcloud users, specify access scopes using the --scopes flag and include the trace.append Cloud Trace API access scope. For example, to create a GKE cluster with only the Cloud Trace API enabled, do the following:

    gcloud container clusters create example-cluster-name --scopes=https://www.googleapis.com/auth/trace.append

Running locally and elsewhere

If your application is running outside of Google Cloud, then you must provide authentication credentials in the form of a service account to the client library. The service account must contain the Cloud Trace agent role. For instructions, see Creating a service account.

Google Cloud client libraries use Application Default Credentials (ADC) to find your application's credentials.

You can provide these credentials in one of three ways:

  • Run gcloud auth application-default login

  • Place the service account in a default path for your operating system. The following lists the default paths for Windows and Linux:

    • Windows: %APPDATA%/gcloud/application_default_credentials.json

    • Linux: $HOME/.config/gcloud/application_default_credentials.json

  • Set the GOOGLE_APPLICATION_CREDENTIALS environment variable to the path to your service account:

Linux/macOS

    export GOOGLE_APPLICATION_CREDENTIALS=path-to-your-service-accounts-private-key

Windows

    set GOOGLE_APPLICATION_CREDENTIALS=path-to-your-service-accounts-private-key

PowerShell:

    $env:GOOGLE_APPLICATION_CREDENTIALS="path-to-your-service-accounts-private-key"
