This web-monitoring tool allows users to track website availability and content changes, along with several notification methods. It features search by masks and multithreaded site checks with low system requirements. Written in C++, it doesn't require MySQL, Perl, PHP, or cron.

The program includes a web interface that lets users adjust the system and monitor the progress and status of their sites. It also has the ability to scan multiple sites simultaneously with multi-threaded site checks. Additionally, there are several methods of user notification, including email, command execution, and GET.
DF Site Monitor (C++) allows users to search by masks, which enables a deeper analysis of the HTML code. For example, masks can determine whether a link is in the document body or inside comments, and whether there are unclosed HTML tags in front of it, which can prevent its correct displaying or SE indexation.
This software also has a "Task" feature, which checks the sites of a particular group once, generates a report, and automates the group deletion. The system can detect freezing sites and increase the check frequency when site status changes to unavailable. Furthermore, it can detect redirects and visit the site where the redirect leads for checking purposes. Users can also truncate page parameters when checking sites and all site status changes are logged.
DF Site Monitor (C++) is a high-performance system fully written in C++. Its reliability comes with minimal system requirements, and it does not use MySQL, Php, Perl, etc. This program features a built-in scheduler that lets it operate without the need for cron usage. It also provides server overload protection, and the number of sites checked per script run can be limited. Moreover, the number of sites monitored is unlimited.
Finally, there is an interface for using DF Site Monitor (C++) as a module for other scripts (API). The program even has an API sample in Perl. Users can test the software to its fullest extent by exploring its demo and trial versions, which are available on the internet.
