Getting Started is Simple

Add the Sentry dependency:

Install-Package Sentry.AspNetCore -Version 3.8.3

Configure Sentry in appsettings.json.

"Sentry": {
  "Dsn": "https://examplePublicKey@o0.ingest.sentry.io/0",
  "MaxRequestBodySize": "Always",
  "SendDefaultPii": true,
  "MinimumBreadcrumbLevel": "Debug",
  "MinimumEventLevel": "Warning",
  "AttachStackTrace": true,
  "Debug": true,
  "DiagnosticsLevel": "Error"
},

Then add the SDK by simply calling UseSentry:

public static IHostBuilder CreateHostBuilder(string[] args) =>
    Host.CreateDefaultBuilder(args)
        .ConfigureWebHostDefaults(webBuilder =>
        {
            // Add the following line:
            webBuilder.UseSentry();
        });

That’s it. Be sure to check out our documentation to ensure you have the latest instructions.

FAQs

Traditional logging provides you with a trail of events. Some of those events are errors, but many times they’re simply informational. Sentry is fundamentally different because we focus on exceptions, or in other words, we capture application crashes. We discuss in more detail here and on our blog.

When Spring Boot is configured to generate Git information every event triggered by Sentry will have a release field set to the current Git commit ID that will enable Monitor Release Health Sentry feature. More details here.

You can get started for free. Pricing depends on the number of monthly events, transactions, and attachments that you send Sentry. For more details, visit our pricing page.
