Port Monitoring

TCP Port Monitoring for Any Service

Monitor databases, mail servers, caches, and any TCP-based service. Get instant alerts when ports stop responding, before your application breaks.

Why Port Monitoring Matters

Your website might be up, but is your database responding? Is your Redis cache available? Port monitoring ensures all the services your application depends on are running and accessible.

Database Monitoring

Monitor MySQL (3306), PostgreSQL (5432), MongoDB (27017), and other database ports to ensure your data layer is always available.

Cache & Queue Services

Track Redis (6379), Memcached (11211), and message queues like RabbitMQ (5672) to prevent application slowdowns.

Mail Server Monitoring

Ensure your email infrastructure is running with SMTP (25/587), IMAP (143/993), and POP3 (110/995) port monitoring.

Custom Application Ports

Monitor any custom port your applications use. If it accepts TCP connections, we can monitor it.

Common Ports to Monitor

Service Default Port Use Case
MySQL 3306 Database connectivity
PostgreSQL 5432 Database connectivity
MongoDB 27017 NoSQL database
Redis 6379 Cache & session store
Elasticsearch 9200 Search engine
SMTP 25/587 Email sending
SSH 22 Server access
FTP 21 File transfer

How It Works

  1. Add Host & Port: Enter the hostname/IP and the TCP port number you want to monitor.
  2. Set Connection Timeout: Configure how long to wait before considering the port unreachable.
  3. Configure Alerts: Choose notification channels - email, Slack, webhooks, or SMS.
  4. Monitor 24/7: We'll continuously check the port and alert you if it stops responding.

Port Monitoring Best Practices

  • Monitor Internal Services: Don't just monitor your website - monitor databases, caches, and queues
  • Use Reasonable Timeouts: Set timeouts based on expected response times for each service
  • Combine with Uptime Monitoring: Use HTTP monitoring for web apps and port monitoring for backend services
  • Monitor from Multiple Locations: Ensure services are reachable from different network paths
