For a more detailed look at server load and network metrics etc, use Ganglia:


The Ganglia graphs are split into three sections: the HPC nodes, the Storage servers, and other System (management, domain-control etc) servers.

Disk-usage summaries


Information on disk-usage summaries will be available soon.

Login attempts

You can see where in the world people are logging into gruffalo using the map below:


Each pin represents a location where one or more IP addresses have attempted to log in (tracked over the last seven days). Successfull logins are coloured green, and unsuccessfull logins are coloured red, with the opacity of the pin fading over time, ie, more solid pins represent more recent attempts.

Remote monitoring

We remotely monitor the status of various public-facing servers using UptimeRobot.
