MDBF: A Tool for Monitoring Database Files

Part of the book series: Lecture Notes in Computer Science ((LNISA,volume 11158))

Abstract

When complex queries are executed in a database system, several files will be accessed such as relational tables, indexes and profiles. Monitoring database files enables us to better understand the query progress and the storage system. In this demo, we present a tool for monitoring file operations such as when the file is accessed and how many bytes are transferred for read and write. The access information is visually displayed at running time, and also stored as historical data for further analysis and optimization. We provide a graphical interface to report and display the results. MDBF is implemented inside a system kernel with a low overhead. The demonstration is performed by using real trajectory datasets and continuous queries employing three different indexes.
