• Depends on: none
• Prerequisite for: Etherlink

Motivation

The goal of this milestone is to be able to monitor a rollup node with a Grafana dashboard.

Scope

Metrics of the rollup node allow us to assess/validate the Etherlink project.

Work breakdown

• Identify the relevant metrics to monitor, useful for the Etherlink project (see #6557)
  • Existing metrics
    • L1 head block processing time
    • Level of the last inbox
    • Number of messages (internal/external) in head's inbox
    • Node info (version, commit hash, commit date)
    • Rollup node info (rollup address, mode, genesis level, PVM kind)
  • Metrics to add
    • Injected operations per block and kind
    • GC workload/memory consumption
    • Published/cemented commitments
• Write a Grafana configuration file utilizing the existing Prometheus metrics (see http://54.155.214.98:3000/d/c23759d8-bab9-4f32-872b-5eda46eb5e89/smart-rollup-node)
• Launch a rollup node on Mondaynet and the Grafana monitoring tool using docker-compose
• Write new Prometheus metrics for the rollup node
