TCP ports monitoring to send you alerts when Timeout and Restored

Port_Alert monitors TCP port connections and sends alerts when connect timeouts happen consecutively — then sends another alert when the service is restored. This license version supports WhatsApp, Email, and Sound alerts.

Features

  • Monitor any TCP port and alert on consecutive connect timeout and when service is restored (status change alerts).
  • Works for common services like FTP(21), SSH(22), Telnet(23), SMTP(25), DNS(53), HTTP(80), POP3(110), MSSQL(1433), MySQL(3306) — and any custom port.
  • Adds 3× PING verification results inside the timeout alert text (helps identify network vs. application issues).
  • Alert once when status changes (normal → timeout, timeout → normal) to prevent repeated notifications while the issue continues.
  • Alert channels: WhatsApp, Email, and Sound.
  • Daily SMS cap option (for SMS-based versions) to avoid message storms; Email alerts can still be sent while SMS is capped.
  • Logs timeout details to files and automatically separates logs by date.
  • Optional “I am Alive” periodic mail notification so you know the program is still running.

Setup: WhatsApp & Email
