The /v1/metrics endpoint emits a small set of pipeline and process gauges in the Prometheus text exposition format. Point a Prometheus scrape job at it to graph pipeline state, freshness, error rate, and uptime.
Like /v1/health, this endpoint does not require a User-Agent header so monitoring systems can scrape it without configuration.

Metrics
astra_pipeline_stage_info
Emitted once per known pipeline stage with a stage label. The currently active stage reports 1; all others report 0. Stages are: idle, fetch-url, download-manifest, parse-manifest, download-bundles, reassemble, resolve-version, fetch-mappings, extract-assets, structure-data, swap.
astra_last_update_timestamp_seconds
Unix timestamp (seconds) of the last successful pipeline tick. 0 when no successful tick has happened yet.
1 when the last pipeline tick ended in error, 0 otherwise.
Uptime of the API process in seconds.
Alert on time() - astra_last_update_timestamp_seconds exceeding two pipeline poll intervals — that matches the staleness threshold used by the /v1/health endpoint.
