Observe traffic and database demand.

Live monitor

accel refreshes cache hits, misses and hit ratio, CDC events and lag, invalidation activity, application protocol traffic, cache occupancy and uptime. Stopped or stale statistics are shown as unavailable.

Runtime and error logs

Use logs for recent runtime output and logs errors for stored error records. Both commands work locally and over SSH. On packaged servers, systemd journal output is also available.

accel logs
accel logs errors 100
journalctl -u enginegrids-accelerator

Cache and storage

The result cache and write queue are in memory. SQLite holds settings and bounded error logs. Queue acceptance is not durable database completion; watch queue depth, failed writes and final drain during operations.

OpenTelemetry

Configure the full OTLP/HTTP metrics endpoint, usually ending in /v1/metrics. Metrics include requests, hits, misses, writes, errors, CDC events, cache bytes, connections and queue depth. Use the secret command for a bearer token.
