When an alert fails to execute, HyperDX now surfaces that error directly in the UI rather than silently dropping it. Previously, users might notice gaps in alert history with no explanation — no error message, no way to debug what went wrong. Now, distinct error icons appear inline when different failure types occur: invalid query, webhook delivery failure, missing webhook configuration, and other invalid setups.
Clicking an error icon shows the specific details needed to diagnose and fix the issue, so users can resolve misconfigured alerts without needing to dig through server logs or file a support request. The goal is to make alert failures self-service: spot the issue, understand it, fix it.
