monitored by a Xymon server using network probes supporting a large and extensible range of protocols, including SMTP, HTTP/S and DNS. Hosts that use a supported operating system can also run a Xymon client (also free software), to additionally collect operating system and application monitoring metrics and report them to the Xymon server. Clients are available for Unix and Linux (in formats including source tarball, RPM and Debian package) from the Xymon download site at Sourceforge. Windows hosts can use the Big Brother client for Windows,
