Q: Are traces stored?

No. Set TracesSampleRate to 0. Transaction items are discarded on ingest. Exception events plus breadcrumbs stay.

Use official sentry-go (fixture captured at 0.28.0). Point Dsn at your Epure host. No Epure Go module.

Use this guide when the process is Go: net/http, Gin, Echo, chi, Fiber, workers, CLIs. Do not use this for JS/TS (→ Browser, Node, Next.js). Full map: Pick your SDK.

Capture exceptions in Go

Install sentry-go, call sentry.Init once, recover or CaptureException, then Flush before exit. Envelope ingest. Grouping uses raw frames.

How do I install sentry-go?

go get github.com/getsentry/sentry-go

Keep existing framework middleware. Only the DSN host changes.

Init the Go SDK

err := sentry.Init(sentry.ClientOptions{
  Dsn:              "http://YOUR_PUBLIC_KEY@localhost:8080/YOUR_PROJECT_ID",
  Environment:      "local",
  Release:          "my-api@0.0.0",
  TracesSampleRate: 0,
})
if err != nil {
  panic(err)
}
defer sentry.Flush(2 * time.Second)

Option	Value
`Dsn`	Required: public key + Epure host + project UUID
`Environment`	Tag for the dashboard filter strip
`Release`	Version string on the issue
`TracesSampleRate`	0; transactions discarded

Flush before exit

Short-lived jobs and CLIs drop the last event if the process exits before the transport drains. Always Flush (or equivalent) on shutdown.

How do I capture errors?

sentry.CaptureException(err)

defer func() {
  if rec := recover(); rec != nil {
    sentry.CurrentHub().Recover(rec)
    sentry.Flush(2 * time.Second)
    panic(rec)
  }
}()

Gin / Echo / chi middleware that already calls CaptureException keeps working after the DSN swap.

What should I see after ingest?

202, then an issue whose title matches the panic or error string, with a stack as sentry-go sent it.

Why does Go never send?

What you see	What to do
CLI exits with no issue	`sentry.Flush(2 * time.Second)` before `os.Exit`
401 / 403	Recopy the DSN from Settings → SDK connection
202, empty Issues	Match the environment chip to `Environment`

No SDK yet? Store curl: Other runtimes.

Does Epure demangle Go stacks?

No. There is no Go symbol server. Grouping uses file, function, and line as sentry-go sends them. Call Flush on shutdown so CLI jobs do not lose the last panic.

Are traces stored?

No. Set TracesSampleRate to 0. Transaction items are discarded on ingest. Exception events plus breadcrumbs stay.
