Ports are numerical identifiers in host to host communications. Most users have probably heard of TCP and UDP ports before, likely when they had to configure their router or firewall to allow or block specific ports on a computer system.
Port Alert is a freeware port monitor that can be used to constantly monitor specific ports and notify the user if a port is not accessible. The program supports both local and remote systems.
The user has to enter a host name or IP address, a port and a description for each computer and port combination that should be monitored by Port Alert.
Common ports like port 80 or 21 can be selected directly from the listing with the possibility to add custom port numbers in case that is needed.
The port monitor will send a query to each entry every 10 seconds by default, a value that can changed in the program’s settings. This should probably be changed to less frequent checks if ports on a third party server are checked with the program.
The alert settings hold the configuration for email and sms alerts as well with email alerts requiring mail server information and sms alerts a membership at the developer’s site. The last option in the settings is the configuration of a program that should be executed whenever a port check fails.
A click on the Start Monitor button will start the port checks in the defined interval. Port Alert placed the wrong program shortcut in the Windows Start Menu during our tests. We had to run it from the program directory instead.
The TCP port monitor worked fine otherwise. It can be downloaded from the developer’s website.
