Berachain Mainnet Snapshots Service

Metrics Access for Chuck

🧀 Current Status

🐻 What This Service Provides

This mainnet snapshots service exposes metrics from 4 running Berachain mainnet nodes for external Prometheus scraping. All nodes share beacon-kit v1.3.5 for consensus. The service also generates and publishes public snapshots for node operators (not yet active).

System-Level Metrics

Node Metrics (Per Installation)

Each installation exposes two Prometheus endpoints:

• CL (Consensus Layer): beacon-kit metrics
• EL (Execution Layer): geth or reth metrics

🧪 Prometheus Configuration

Pick the monitoring groups you want. You can monitor system metrics only, just consensus layer, just execution layer, or everything.

All scrape configs include labels service="mainnet-snapshots" and host="mainnet-80094-snapshots" for filtering in your Prometheus queries.

📝 Service Details

• Domain: bera.tinyplanet.ca is temporary until berachain domain is available
• SSL Certificates: Auto-renew via certbot.timer (expires 2026-04-13)
• Scrape Interval: 30s recommended (adjust for your retention/load)
• Architecture: Exporters only (no local Prometheus server)
• Security: All metrics require HTTP basic auth; snapshot site will be public

🔧 Infrastructure Background

This section documents the underlying setup (for reference, not required for metrics access).

Storage

• /srv/chain: 7.0TB RAID0 (2×3.5TB NVMe, chain state for all 4 nodes)
• /srv/snapshots: 1.8TB NVMe (snapshot generation and public serving)

Security

• UFW firewall: SSH (22), HTTP (80), HTTPS (443), P2P ports (42x01, 42x12 TCP/UDP)
• All RPC/metrics endpoints bound to localhost only
• Nginx reverse proxy with HTTP basic auth for metrics

Services

• 4 berabox node installations (geth/reth × pruned/archive)
• prometheus-node-exporter (system metrics)
• nginx (reverse proxy + SSL termination)
