CeloHT Monitoring Architecture

Version: 1.0 Project: CeloHT

1. Purpose

This document defines the monitoring architecture used to observe CeloHT applications, infrastructure, APIs, databases, blockchain integrations, and security events.

Monitoring should provide early detection of failures and abnormal behavior.

3. Monitoring Layers

CeloHT monitoring should cover:

  1. Frontend
  2. API
  3. Database
  4. Infrastructure
  5. Blockchain
  6. Smart contracts
  7. CI/CD
  8. Security
  9. Business metrics

4. Application Monitoring

Monitor:

  • Application availability
  • Page errors
  • JavaScript errors
  • API failures
  • Response latency
  • User-facing failures

5. API Monitoring

Track:

Request Rate
Error Rate
Latency
Status Codes
Authentication Failures
Rate Limits

Useful indicators include:

  • Requests per minute
  • Error percentage
  • p50 latency
  • p95 latency
  • p99 latency

6. Database Monitoring

Monitor:

  • Availability
  • CPU
  • Memory
  • Storage
  • Connections
  • Query latency
  • Slow queries
  • Backup status
  • Failed queries

7. Infrastructure Monitoring

Infrastructure monitoring should include:

  • CPU utilization
  • Memory utilization
  • Disk usage
  • Network traffic
  • Service availability
  • Deployment status

8. Blockchain Monitoring

Monitor:

  • RPC availability
  • Transaction submission
  • Transaction failures
  • Confirmation delays
  • Network mismatch errors
  • Contract events

9. Smart Contract Monitoring

Where appropriate, monitor:

  • Contract events
  • Administrative changes
  • Large transfers
  • Unexpected activity
  • Failed transactions
  • Pause/unpause operations

High-value contract events should receive increased monitoring attention.

10. Treasury Monitoring

Treasury monitoring should focus on:

  • Transfers
  • Authorized signers
  • Large transactions
  • Unexpected destinations
  • Administrative changes

Example:

 ▼         ▼
Normal   Suspicious
            │
            ▼
           Alert

11. Security Monitoring

Security monitoring should detect:

  • Authentication anomalies
  • Repeated failed access
  • Suspicious API activity
  • Privilege changes
  • Secret exposure
  • Unexpected deployments
  • Abnormal blockchain activity

12. CI/CD Monitoring

Track:

  • Build failures
  • Deployment failures
  • Unexpected workflow changes
  • Failed security checks
  • Dependency alerts
  • Deployment frequency

13. Business Monitoring

Technical monitoring should be complemented by business metrics.

Potential CeloHT indicators:

  • Users trained
  • Completed training
  • Active agents
  • Transactions
  • Remittance activity
  • Reforestation activity
  • Revenue
  • Community participation

Each metric must have a documented definition.

14. Alerts

Alerts should be actionable.

Bad alert:

Something happened.

Better alert:

API error rate exceeded threshold for 10 minutes.

An alert should ideally include:

  • What happened
  • When it happened
  • Affected service
  • Severity
  • Relevant diagnostic information

15. Alert Severity

Critical

Immediate response required.

High

Prompt investigation required.

Medium

Investigation during normal operational windows.

Low

Informational or trend monitoring.

16. Dashboards

Recommended dashboards:

System Health

Availability
API Errors
Latency
Infrastructure
Database

Blockchain

RPC Health
Transactions
Failures
Confirmation Times
Contract Events

Security

Authentication Failures
Suspicious Requests
Privileged Changes
Security Alerts

Impact

Users Trained
Agents
Transactions
Reforestation
Revenue

17. Logging Principles

Logs should be:

  • Structured
  • Searchable
  • Timestamped
  • Correlated using request IDs where appropriate

Logs must not contain:

  • Private keys
  • Seed phrases
  • Passwords
  • API secrets
  • Sensitive authentication tokens

18. Observability Correlation

Where possible:

User Request
     │
     ▼
Request ID
     │
     ├── API Log
     ├── Database Log
     ├── Blockchain Operation
     └── Error Event

This allows engineers to trace failures across system boundaries.

19. Monitoring Data Retention

Monitoring data should have defined retention periods.

Security logs may require longer retention than ordinary application logs.

Retention should balance:

  • Investigation needs
  • Cost
  • Privacy
  • Compliance requirements

20. Incident Integration

Monitoring connects directly to incident response.
