New PGP keys

We've updated our PGP keys with new ones that conform better to current best practices. If you're relying on them to validate our software please grab our new keys instead.

Old ticket tracker removed

Our old email based support system has now been deprecated, along with the two email addresses that pointed at it - bugs@ and support@. The main reason for this was the sheer amount of spam we were getting, even with anti-spam measures in place. But also because the amount of issues logged outweighs the need to run our own system at the moment.

If you have an issue to report, please see our bug reporting page for more information on the best way to do it. If you had an outstanding issue in the old system we should have contacted you by now, so if you haven't heard anything from us assume it got lost and log a new issue as described on the aforementioned page.

libstatgrab is a library and tool set for acquiring system statistics from the operating system. An API is provided for other applications to easily accesses a variety of system statistics, including, amongst other things, CPU usage, VM usage, disk statistics, and network interface usage.

A handful of tools are also provided to make this information more readily available to users. A curses based tool gives users a "top like" view of the current state of their system, and a "sysctl like" tool gives easy access to the statistics for other applications that can't easily used the C API.

Finally scripts are provided to quickly setup MRTG to use libstatgrab for generating graphs of the available statistics.


pystatgrab is a set of Python bindings for the libstatgrab library. It provides a set of function calls identical to those of libstatgrab, and returns data in structures that logically map on to those of libstatgrab.
