Guide to Uptime Monitoring
What is Uptime Monitoring?
Uptime monitoring is a service that regularly checks if your website is online and functioning properly. Tinylytics uptime monitoring provides:
- Regular health checks of your website
- Immediate notifications when your site goes down or comes back up
- SSL certificate monitoring and expiration alerts
- Historical uptime statistics and event tracking
- Easy display of uptime stats on your website
How It Works
Monitoring Process
- Regular Checks: Tinylytics checks your website every 5-10 minutes when it’s functioning normally.
- Multiple Verification: When a potential downtime is detected, the system:
- Marks it as potential downtime
- Performs multiple verification checks with increasing timeouts
- Uses smart retry logic to confirm actual downtime
- Only sends notifications once downtime is confirmed
- Smart Retry System:
- First attempt: 30-second timeout
- First retry: 60-second timeout
- Subsequent retries: 120-second timeout
- Exponential backoff between retries (with jitter)
- IPv4 fallback for network issues
- Adaptive Monitoring: Check frequency automatically adjusts based on site status:
- When your site is up: Checks every 5-10 minutes
- When your site just went down: Checks every minute
- After 24 hours of downtime: Reduces to every 10 minutes
- After 48 hours of downtime: Reduces to every 30 minutes
- After 7 days of downtime: Auto-pauses monitoring (can be resumed anytime)
SSL Certificate Monitoring
For HTTPS sites, Tinylytics also monitors your SSL certificate:
- Validates certificate authenticity

Troubleshooting Common Issues
Site Shows as Down But It’s Working
Possible causes:
- Bot protection or firewall blocking monitoring requests
- Rate limiting from security tools
- Regional networking issues
Solutions:
- Whitelist the Tinylytics User Agent in your firewall settings
- Configure Cloudflare to allow Tinylytics monitoring requests
- Verify bot protection settings
- Contact support if issues persist
Firewall and CDN Configuration
Tinylytics uses a specific User Agent for uptime checks:
Tinylytics Uptime Monitor/1.0
If you’re using Cloudflare or similar services, you should create a rule to allow requests with this User Agent. Otherwise, your firewall might block our health checks, resulting in false downtime alerts.
For Cloudflare users:
- Go to your Cloudflare dashboard
- Navigate to Security → WAF → Create Rule
- Create a rule that allows traffic when the User Agent contains “Tinylytics Uptime Monitor”
- Set the rule to “Skip” security features for matching requests
SSL Certificate Warnings
Common issues:
- Certificate approaching expiration
- Self-signed certificates
- Incomplete certificate chains
- SNI (Server Name Indication) configuration problems
Solutions:
- Renew certificates before they expire
- Use trusted certificate authorities
- Configure proper certificate chains
- Set up SNI correctly for shared hosting
Plan Features and Limitations
- Free Plan: No uptime monitoring
- Paid Plans: Full uptime monitoring and SSL certificate monitoring
Best Practices
- Place the uptime display in your footer or status page
- Combine with hit counters for more comprehensive stats
- Resume monitoring promptly after auto-pause
- Keep your SSL certificates up to date
- Use the monitoring data to improve your hosting setup
