6. Non-Functional Requirements

| Area | Requirement | |-------|--------------| | Performance | Comparison must complete in < 100ms | | State persistence | Store previous health state (e.g., Redis, SQLite, S3) | | Idempotency | Rerunning same check should not trigger duplicate alerts | | Configurability | Ability to ignore certain failure types from “new failure” detection | asm health checker found 1 new failures

Recent rolling deployment, configuration commit, or scaledown/scaleup around the timestamp.
Hardware alerts from infrastructure providers or cloud provider incident notices.

He dug deeper into the ASM logs. The health checker hadn't flagged a total crash; it had flagged a "Zombie Process" in the health-check script itself. A legacy script, written years ago by an engineer who had long since moved on, had timed out while trying to ping a decommissioned staging server. ASM Health Checker Found 1 New Failure: What

Part 6: Preventing Future Occurrences

The asm health checker found 1 new failures message is often a symptom of deeper operational drift. Implement these best practices: Check name & ID Exact error message and

Potential Impact

Reduced redundancy for the affected disk group (if using normal or high redundancy)
Possible performance degradation during write operations
Increased risk of data unavailability if another disk in the same failure group fails before recovery
