Port Monitoring
Know When a Port
Stops Responding
Monitor any TCP port — databases, web servers, mail servers, SSH, custom services — and get instantly alerted when a port goes closed or unresponsive.
Monitor Any Port on Any Server
-
TCP port monitoring
Monitor any TCP port — 80, 443, 3306, 5432, 6379, 22, 25, or any custom port your service uses.
-
Connection timeout configuration
Set custom connection timeouts to match your service's expected response behaviour.
-
Multi-location verification
Checks from multiple global locations confirm real outages — never wake up for a false alarm again.
-
Response time tracking
Track TCP connection times over time and spot performance degradation early.
-
Common ports pre-configured
Quick-select common services (MySQL, PostgreSQL, Redis, SSH, SMTP) for instant setup.

Common Port Monitoring Use Cases
Database Availability
Monitor MySQL (3306), PostgreSQL (5432), or MongoDB (27017) to catch DB outages before they bring down your app.
Web Server Health
Verify HTTP (80) and HTTPS (443) ports are open independently from your URL monitor.
Mail Server
Monitor SMTP (25/587) and IMAP (993) ports to ensure email delivery is working.
Cache Services
Track Redis (6379) or Memcached (11211) availability to prevent cascading failures.
SSH Access
Monitor SSH (22) to know immediately if remote access to a server is lost.
Custom Services
Any internal service on a custom port — game servers, APIs, message queues — monitored instantly.
