ProtoMon is a server monitoring software (network monitoring software, website monitoring software) what continuously checks your servers at specified intervals and notifies you when one or more of them is not responding. So you can immediately take the steps to resolve the problem, minimizing the downtime.

The Internet and network servers monitoring:
1. Website monitoring (HTTP, HTTPS). The program supports all types of queries, HTTP authentication, proxy servers with authorization, redirects, content checking, etc.
2. File server monitoring (FTP, FTPS, SFTP). The monitoring software can download a file from the file server and check its content using the boolean expressions filter.
3. Email server monitoring (SMTP, POP3, IMAP). ProtoMon supports the secure versions of all mail protocols. It can check the messages count and the folders list, and can send a test message on every monitor check.
4. Telnet monitor and SSH monitor. The software can execute a script on the remote computer, grab its output, and check it using the content filters with support of the boolean expressions.
5. Check the connection to any TCP server on any port.

When a monitor check fails, ProtoMon can do the following actions:
1. Show a pop-up notification window.
2. Play a sound.
3. Send a notification e-mail message.
4. Launch any external application, file or URL.

ProtoMon can identify the Internet connection failures, thus you can:
1. Get separate statistics for the servers downtime and the Internet connection problems.
2. Specify, whether you wish to trigger the alerts when Internet connection fails, or not.
3. Force ProtoMon to re-check the monitors more frequently if the Internet is not available.

The program supports a wide range of network protocols including ICMP, HTTP, FTP, POP3, IMAP, SMTP, Telnet/SSH, SFTP and TCP.

ProtoMon can monitor system information of any Windows computer. There are more than 30 parameters that can be monitored. Among them are the CPU and memory usage, files and processes information, registry values and much more.

Also the program can execute any console application and monitor its output.
