HyperSentry is a simple web services monitor that allows you to monitor HTTP, SMTP, FTP, IMAP, POP3 and PING responses from an unlimited number of hosts. If a service does not respond within the defined timeout, the software can alert you by sound, pop-up window, email alert and/or HTTP post. HyperSentry is easy-to-use, suitable for non-technical users, but lacks the features and flexibility of more advanced monitoring tools.
