  • Quick start instructions
  • Metric descriptions
  • Alert documentation
  • Docker deployment
  • Security best practices
  • Troubleshooting guide
  • Additional resources

🎨 Dashboard Design

Theme: Dark terminal (matches RustChain aesthetic)
Color Coding:

• Green: Healthy / Normal / Good
• Yellow: Warning / Degraded
• Red: Critical / Bad

Panel Types:

• Stat panels for current values
• Timeseries charts for trends
• Pie chart for distribution
• Gauge for health score
• Progress bars for resource usage

🚨 Alert Routing

Critical → PagerDuty / Opsgenie / Email
Warning → Slack / Discord / Email
Info → Logging only

Configure in grafana/alerts.yml under alertmanagers section.

📊 Prometheus Metrics Required

The dashboard expects these metrics from RustChain node:

``
rustchain_miners # Active miner count
rustchain_attestations_total # Total attestations
rustchain_current_epoch # Current epoch number
rustchain_balance_rtc # Total RTC balance
rustchain_transfers_total # Transfer count
rustchain_epoch_rewards_distributed # Epoch rewards distributed
rustchain_node_health # Node health score (0-1)
rustchain_api_request_duration_seconds # API response time
rustchain_api_requests_total # Total API requests
rustchain_api_errors_total # Total API errors

### 🔍 Monitoring Coverage

**Network Health:**
- Active miner count
- Attestation rate
- Node availability

**Token Economics:**
- Total supply tracking
- Transfer volume
- Reward distribution

**System Performance:**
- API latency (p95)
- Request rate
- Error rate

**Resource Utilization:**
- Disk space (Prometheus node_exporter)
- Memory usage (Prometheus node_exporter)
- CPU usage (Prometheus node_exporter)

### 📈 Expected Impact

**Visibility:**
- Real-time network health monitoring
- Proactive alerting for critical issues
- Historical trend analysis
- Resource utilization tracking

**Operations:**
- Reduce mean time to detection (MTTD)
- Automated incident response
- Data-driven capacity planning

**Quality:**
- Ensure consistent node performance
- Detect unusual patterns early
- Maintain service level agreements (SLAs)

### 🧪 Testing

**Load Testing:**
- Simulate miner connections
- Generate high volume API requests
- Test alert firing thresholds

**Dashboard Testing:**
- Import dashboard to test Grafana instance
- Verify all panels load correctly
- Test alert rules with synthetic data

### 🔧 Customization

**Adding New Panels:**
1. Edit dashboard in Grafana UI
2. Click "Add panel"
3. Select metric and visualization
4. Configure thresholds and colors

**Adding New Alerts:**
1. Edit `grafana/alerts.yml`
2. Add new alert rule with severity
3. Configure annotations and labels
4. Reload Prometheus

Thanks for the work here — there is a lot of effort, but this PR is not safely mergeable in current form.

Blocking findings:

1. Scope is bundled across multiple unrelated bounties in one PR

• This PR simultaneously includes Grafana (#21), Docker deploy (#20), mining pool proxy (#258), SEO site (#257), and mining badge (#256).
• Impact: review signal is diluted, rollback blast-radius is huge, and payout mapping becomes ambiguous.
• Required fix: split into focused PRs (one bounty per PR), each with isolated diff and validation.

2. Change size is too large for safe review/merge (6,651 additions across 31 files)

• With this size, it is not possible to reliably validate operational safety (deployment/security/runtime behavior) in one pass.
• Required fix: keep each PR narrowly scoped with only files necessary for that deliverable.

Once split into smaller, bounty-scoped PRs, I can re-review quickly.
