Defined in:

Overview

Runs all registered checks and rolls them up into a single status.

Status semantics:

:ok           — every check returned :ok
:degraded     — at least one non-critical check failed
:unavailable  — at least one critical check failed

The aggregator never raises. Each check is invoked through ‘safe_run` which catches `StandardError` so a buggy custom check cannot take down /ready.
