Monitor Render Services with Health Checks

Never wake up to a down service again. Get instant alerts when things break.

What You'll Build

A monitoring system that:

• Pings all your Render services every 5 minutes
• Checks HTTP status codes and response times
• Alerts you immediately when services go down
• Tracks uptime and generates weekly reports

Requirements

• Plugins: Render (from Lobstash.ai), Web Search
• Time: 5 minutes

Setup

1. Install Render Plugin

Connect Render account List all services

2. Configure Health Checks

Every 5 minutes, check: - Service: my-api (https://my-api.onrender.com/health) - Service: my-frontend (https://my-app.onrender.com) - Service: my-worker (via Render API status) Expected: 200 status code, response time <2 seconds

3. Set Up Alerts

Alert me on Telegram if: - Any service returns non-200 status - Response time >5 seconds - Service crashes or enters "suspended" state - Render dashboard shows degraded performance Do NOT alert if: - Service is in "sleeping" state (expected for free tier)

4. Weekly Reports

Every Monday at 9 AM, send: - Uptime % for each service - Average response times - Number of incidents last week - Any services that need attention

Sample Alert

Service Down:

🚨 RENDER ALERT Service: my-api Status: DOWN (500 error) Last successful check: 8 minutes ago Response time: timeout [View logs on Render →](https://dashboard.render.com/...) Attempting auto-restart...

Auto-Recovery:

✅ Service Recovered Service: my-api Status: HEALTHY Downtime: 12 minutes Auto-restart: successful Logs show: memory limit exceeded → increased instance size recommendation

Sample Weekly Report

📊 Render Weekly Report — Feb 5-11 🟢 my-api Uptime: 99.8% Avg response time: 245ms Incidents: 1 (auto-recovered) 🟢 my-frontend Uptime: 100% Avg response time: 180ms Incidents: 0 🟡 my-worker Uptime: 95.2% Downtime: 8 hours (planned maintenance) Incidents: 0 🎯 Recommendations: - Upgrade my-api to 2GB RAM (hit limits 3x this week) - Enable Redis caching for my-frontend (response times trending up)

Pro Tips

1. Custom Health Endpoints: Create /health routes that check database, Redis, etc.
2. Incident Tracking: Log every alert to a Notion database for post-mortems
3. Auto-Scaling: If monitoring detects consistent slow responses, trigger Render API to scale up
4. Cost Alerts: Get notified when Render bill exceeds monthly threshold
