Q: Are traces stored?

No. Set traces_sample_rate and profiles_sample_rate to 0. Those item types are discarded on ingest. Exception events plus breadcrumbs stay.

Capture exceptions from Rails, Sinatra, and Sidekiq with sentry-ruby pointed at Epure.

Use official sentry-ruby (fixture captured at 5.18.0). Point dsn at your Epure host. No Epure gem.

Use this guide when the process is Ruby: Rails, Sinatra, Sidekiq, scripts. Do not use this for JS/TS (→ Next.js). Full map: Pick your SDK.

Capture exceptions in Ruby

Install sentry-ruby (and sentry-rails / sentry-sidekiq if you already use them), call Sentry.init once, then raise or capture_exception. Envelope ingest. Grouping uses raw frames.

How do I install sentry-ruby?

gem install sentry-ruby

In a Gemfile, keep sentry-rails and sentry-sidekiq if they are already there. Only the DSN host changes.

Init the Ruby SDK

Sentry.init do |config|
  config.dsn = ENV.fetch("SENTRY_DSN")
  config.environment = "local"
  config.release = "my-app@0.0.0"
  config.traces_sample_rate = 0.0
  config.profiles_sample_rate = 0.0
end

Local compose DSN shape:

http://YOUR_PUBLIC_KEY@localhost:8080/YOUR_PROJECT_ID

Option	Value
`dsn`	Required: public key + Epure host + project UUID
`environment`	Tag for the dashboard filter strip
`release`	Version string on the issue
`traces_sample_rate`	0; transactions discarded
`profiles_sample_rate`	0; profiles discarded

Rack middleware and sentry-rails stay. Unrescued controller exceptions still post envelopes after the DSN swap. Sidekiq can share the web project or use a second DSN.

How do I capture handled errors?

begin
  risky
rescue => e
  Sentry.capture_exception(e)
  raise
end

What should I see after ingest?

202, then an issue whose title matches the exception class and message, with a stack as sentry-ruby sent it.

Why does Ruby never send?

What you see	What to do
401 / 403	Recopy the DSN from Settings → SDK connection
202, empty Issues	Match the environment chip to `config.environment`
Job throws missing	Init the SDK in the Sidekiq process, not only `rails server`

Does Epure demangle Ruby stacks?

No. There is no Ruby symbol server. Grouping uses file, method, and line as sentry-ruby sends them. Confirm with Verify.

Are traces stored?

No. Set traces_sample_rate and profiles_sample_rate to 0. Those item types are discarded on ingest. Exception events plus breadcrumbs stay.
