DENY/circuit-breaker
Circuit breaker open
Repeated failures on this tool tripped the breaker; calls are shed until it half-opens.
What it means
Aarmos tracks failure rates per tool. When a threshold trips, the breaker opens and denies further calls for a cool-down window, preventing cascading failure and cost.
Common causes
- Upstream tool returning 5xx or timing out.
- Credential expiry causing repeated auth failures.
How to fix
- Fix the upstream cause first; the breaker will half-open automatically.
- Re-authenticate the adapter if failures were auth-related.
