Where the closed loop earns its keep.

A connection-pool exhaustion incident in the trading database cascaded into order-rejection alerts and exchange-side timeouts. On-call had to correlate Loki logs, Prometheus graphs, and a recently-shipped migration under pressure.

OpsKeeper grouped the 47 raw alerts into one incident, traced the RCA back to a connection-pool floor mismatch on the new replica, and proposed raising the floor with explicit blast radius. A human approver signed it in 90 seconds. The verifier confirmed recovery from a four-metric allowlist.

A single noisy tenant on a shared Postgres cluster pushed replica replay lag past 60 seconds for everyone. The platform team needed to identify the tenant and route only their reads away, without affecting the other 1,200 tenants.

OpsKeeper correlated the lag spike to one tenant via Qdrant vector recall on historical patterns, drafted a proposal to enable read-only routing for that tenant, and verified recovery against the replay-lag allowlist. The loop ran end-to-end without paging a human until the approval gate.

A regional POP lost upstream connectivity. Local POS terminals kept running on the edge cache but the central OpsKeeper control plane was unreachable. The team needed an autonomous edge that could still emit a clean audit trail.

The opskeeper-edge daemon buffered evidence locally and reconnected to the control plane when the POP recovered. The HMAC-chained ledger replayed end-to-end on the central side, with no audit gap and no manual reconciliation.

A nightly checkpoint on the historian database collided with peak-shift IOPS and saturated the disk subsystem. Production telemetry started dropping. Manual intervention was not an option — the line could not stop.

OpsKeeper detected the disk-saturation pattern, traced it to the checkpoint window, and proposed spreading checkpoints across two replicas. The repairer staged the change, the verifier confirmed IOPS recovered below the alert threshold, and the postmortem was auto-drafted for the next morning.

A dropped index from a previous release caused lock waits longer than 30 seconds during a global event launch. Player-facing queries stalled and the on-call was staring at a chain of blocked transactions.

The investigator traced the blocker back to a single batch job, the reviewer signed off on cancelling it with explicit blast radius, and the verifier confirmed lock waits returned to baseline. The postmortem landed in the team Slack within 60 seconds of recovery.
