# Monitoring

> Operational signals for the web, API, indexer, and data plane.

## Service health

* Web process availability and page render success.
* API `/health` for process liveness and `/readyz` for database readiness.
* PostgreSQL and Redis container health checks.
* Migration job completion before API/indexer startup.

## Chain and indexer health

* Current Base Mainnet head versus finalized indexer checkpoint.
* Checkpoint age and hash continuity.
* RPC latency, retry exhaustion, rate limiting, and chain-ID mismatch.
* Reorg recovery activity and noncanonical row counts.
* Launch discovery, trade projection, and matched graduation-settlement errors.

## Data integrity

* Fee/vault liabilities versus contract or database backing, depending on the layer being checked.
* Canonical projection counts and exclusion behavior.
* Metadata drafts that remain unfinalized after a confirmed launch.
* Null OHLC fields treated as unavailable rather than zero.
* Oracle freshness and `oracle_unavailable` rate.

<Note>
  An API or indexer alarm does not imply onchain financial state changed. Start incident tracing from receipt and block provenance, then checkpoint, canonical raw events, projections, API, and frontend.
