The rollup node should have telemetry for both debugging and prod usage.
We should start with a standard fmt + prometheus stack to collect both traces and metrics:
Metrics collection: Use metrics crate to gather crate performance / monitoring data.
Prometheus: Set up a Prometheus subscriber to expose metrics via a /metrics endpoint.
Fmt Layer: Add structured logging with a fmt layer for human-readable logs.
CLI Configuration
Add a CLI flag (e.g., --metrics) to toggle prometheus.
Allow configuration of the Prometheus port via --telemetry-port=.
Tasks
Integrate metrics and metrics-exporter-prometheus.
Set up Prometheus exposition and logging with fmt.
Add CLI flags for telemetry control.
Test and document the telemetry functionality.
NOTE: some metrics will be especially useful for debugging. Here is one example to keep in mind.
