The path
One order, from the alert to the timeout
order_8421 is one failed order. Each screen below is filtered to it, so you never line up timestamps across two tools.
- alert T+0:00 · order order_8421
The alert fires on the checkout route only
Error rate on POST /checkout crosses its threshold while the rest of the site is healthy. The sale traffic is fine. The payment path is not.
- trace T+0:25 · order order_8421
The trace ends at Stripe
Open one failed order. Three retries sit at the bottom of the waterfall in red, each timing out at exactly 1.75 s, the client's own deadline.
- logs T+2:10 · order order_8421
The logs say the pool was empty
The log lines from those spans share the same trace id. They show the retry budget running out and the connection pool at capacity. The requests timed out waiting for a connection.
