TCP Monitor

The TCP monitor checks if a specific port on a server is open and accepting connections.

Configuration Options

When setting up a TCP monitor, you can configure the following options:

Basic Settings

• Name: A descriptive name for your monitor.
• Group: Optional group assignment for organizing monitors.
• Interval (seconds): How frequently updu should perform the check.
• Timeout (seconds): The maximum time updu will wait for a connection before considering the check failed.

TCP Specific Settings

• Host / IP: The hostname or IP address of the server (e.g., 192.168.1.100 or db.example.com).
• Port: The specific network port to check (e.g., 3306 for MySQL, 5432 for PostgreSQL).

Example Use Cases

• Database Availability: Ensure your internal database server is accepting connections on its standard port.
• Network Services: Check if an FTP server is running on port 21.
