ProtoMon is a robust server monitoring software intended to check your servers and let you know when some of them are down.

It supports the following network protocols:
- ICMP
- HTTP(HTTPS)
- FTP(FTPS)
- POP3(POP3S)
- IMAP(S)
- SMTP(SMTPS)
- Telnet(SSH)
- SFTP
- Custom TCP connections

If a server is not responding, the program will perform any of these actions:
- send a notification e-mail message
- display a pop-up notification window
- play a sound

Also ProtoMon can do some additional actions, such as filter the downloaded content, check the Internet connection, download a file while checking an FTP or SFTP server, send a test e-mail message while checking an SMTP server, execute the scripts via Telnet or SSH, etc.

The program keeps network monitoring statistics, and displays it both in text and chart forms.

You can review the server statuses and statistics remotely, using your favorite web browser. This can be done in two different ways. ProtoMon includes a built-in web server, thus you can start it and connect directly. Or you can configure the program to create the static web pages within desired intervals and place them to the specified folder. This allows you to use your default web server (Apache, IIS, or any else) to access this information.
