Diagnosis Agent

ran in parallel

The degraded status alert was triggered by the scheduled node‑pool maintenance window, which intentionally puts nodes into a reduced‑capacity state; this does not impact customer traffic, making the alert a false positive tied to maintenance activity.

ran in parallel

P4 / infrastructure

Routed to: infrastructure-platform-team

The incident is a known, expected state occurring during a scheduled maintenance window. There is no customer impact, and historical data indicates this is a recurring alert for anticipated infrastructure activities.

Scenario Matcher

deterministic, pre-LLM

Scheduled maintenance window overlap

Alerts overlapping a known maintenance window are expected noise; no automated remediation action is warranted.

Match score: 87% · Recommended action: no_action_needed

Matched tags: maintenance, scheduled, overlap

Remediate Agent

grounded by runbook match, pre-gate

Proposed action: no_action_needed

The alert was triggered by a scheduled node‑pool maintenance window and does not affect customer traffic. The diagnosis confirms this is a false positive, and the matched runbook explicitly recommends no_action_needed for such cases. Therefore, no remediation action is required.

Resolved · residual risk: none

Follow-up: none

The alert was identified as a false positive caused by a routine, scheduled maintenance window which is expected behavior. No impact to customer traffic was observed, and the action taken adheres strictly to the documented runbook.
