Push-based monitoring system with heartbeats

[mostronatorcoder]

Summary

Implement a push-based monitoring system where the bot sends heartbeats every 2 minutes to an external monitor service. This approach is non-invasive (no changes to core bot architecture) and provides comprehensive health monitoring.

Implementation Plan

Phase 1: Bot Integration (Week 1)

• Create monitoring.ts module
• Add environment variables to .env-sample
• Integrate heartbeat into bot startup
• Test heartbeat functionality

Phase 2: Monitor Service (Week 2)

• Create monitor service for Digital Ocean
• Implement heartbeat reception and analysis
• Set up smart alerting system
• Deploy to Digital Ocean App Platform

Phase 3: Testing & Documentation (Week 3)

• Test full alerting pipeline
• Set up UptimeRobot for monitor service
• Document configuration options
• Create monitoring dashboard

Benefits

• Proactive Detection: Know about issues within 2-6 minutes
• Non-invasive: No changes to bot's core architecture
• Comprehensive: Monitors all critical components (bot, DB, Lightning)
• Configurable: Flexible intervals and alerting thresholds
• Cost-effective: ~$5/month for 24/7 monitoring
• Reliable: Multiple layers of monitoring with failover

Success Criteria

• Bot sends heartbeats every 2 minutes with full health data
• Monitor service receives and analyzes heartbeats correctly
• Critical alerts sent within 6 minutes of issues
• Warning alerts properly throttled to prevent spam
• Status dashboard shows real-time bot health
• System tested with simulated failures

This monitoring system will ensure administrators are notified within minutes when the bot experiences issues, preventing extended downtime and maintaining user trust.

Push-based heartbeats are definitely the way to go here, especially since it bypasses the usual firewall headaches you get with pull-based checks on LN nodes. I’ve been using Pulsetic (https://pulsetic.com/) for this exact scenario,their heartbeat monitoring handles the alerting logic out of the box so you don't have to build a custom monitor service on Digital Ocean from scratch.

thanks adrian, it makes sense that pulsetic service looks really great and in another time I would have gone for that option, but building our own custom monitor service right now is really cheap on time and resources with AI agents, then the deploy is really cheap
