MARS 1.4 – MARS is a Java application designed to help system administrators monitor the status of Internet servers they manage. It currently monitors SMTP, POP3, IMAP, HTTP, FTP, and SSH, as well as load average, free disk space, and free memory (with an included Perl server, named SPOTS, placed on each monitored machine). It can alert you of problems via alert boxes displayed on your desktop or (optionally) via e-mail or e-mail based paging systems.
