Getting Started is Simple

Install the NuGet package to add the Sentry dependency:

Click to Copy
dotnet add package Sentry

Initialize the SDK as early as possible, like in the Main method in Program.cs/Program.fs:

Click to Copy
using (SentrySdk.Init(o => {
  // Tells which project in Sentry to send events to:
  o.Dsn = "https://<key>@sentry.io/<project>";
  // When configuring for the first time, to see what the SDK is doing:
  o.Debug = true;
  // Set TracesSampleRate to 1.0 to capture 100% of transactions for Tracing.
  // We recommend adjusting this value in production.
  o.TracesSampleRate = 1.0; }))
{
  // App code goes here - Disposing will flush events out
}

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.
