Collection and Exploration of Large Data Monitoring Sets Using nProbe
Collecting and exploring monitoring data is becoming increasingly challenging as networks become larger and faster. Solutions based on both SQL-databases and specialized binary formats do not scale well as the amount of monitoring information increases. This paper presents a novel approach to the problem by using a bitmap database that allowed the authors to implement an efficient solution for both data collection and retrieval. The validation process on production networks has demonstrated the advantage of the proposed solution over traditional approaches. This makes it suitable for efficiently handling and interactively …
