Existing systems-management tools are essentially a plumbing infrastructure: they collect data and present it to administrators, typically with an API to allow administrators to code scripts for automated analysis. Plumbing is the easy part; analysis is the hard part; this talk will describe our research on creating effective run-time behavioural models of log and metric data, together with work on how to then use that data for fault localisation and diagnosis, leading to self-recovering systems. Given the large costs of running enterprise information systems ($100 billion annually in the US alone; US Bureau of Labor Statistics), our research is expected to result in very significant cost reductions.
