iStat Server for Linux, FreeBSD and Solaris is now available. It has been developed by William Tisater and released as open source, which should encourage rapid development and wide platform support. Anyone is welcome to submit patches.
While it has not been built by Bjango, we endorse William's version as the official Linux, FreeBSD and Solaris release.
You can download it from GitHub:
