One of the research directions of DBlab is: Cloud Storage andAnalysis of System Monitoring Data.


Systems Monitoring Data typically comprises log-files or messages from the monitoring infrastructure in a computing center. By analyzing it is possible to gain in depth knowledge about common resource bottlenecks, correlated use of different resources, but also to derive and predict failure patterns or allow for provisioning. Systems monitoring data is one of the classical examples for Big Data, analyzing it is a key field of application for BigData Analytics methods.

In the frame of an yearly masters project we lay the foundations in the above field by analyzing certain scenarios, correlating resource usage patterns and examining system interdependencies.


DBlab has been active in the field of cloud storage for years. We address aspects of building high performance cloud storage to system virtualization and load optimization. Some of the most relevant papers are listed below.
