DATABASE SNAPSHOT ANALYSIS

摘要

Analysis tools summarize and provide statistics from snapshot files. The analysis tools may provide a temporal view of the changes of the data values across two or more periods of time from one or more snapshot files to show trends in performance of the system. The analysis tools may include meta-data definitions for different sources of the snapshot information.

1. A system for providing statistic data for a database, the system comprising:
one or more processors; a non-transitory computer-readable storage medium storing a plurality of instructions, which, when executed, cause the one or more processors to:
define a time period of analysis of a snapshot information dataset, the snapshot information dataset comprising data relating to a state of the database at multiple instances of times;define a data field of the snapshot information to capture for analysis;load a meta-data definition for the data field of the snapshot information dataset;collect the data field from the snapshot information dataset using the meta-data definition;compute a set of statistics over the time period of analysis for the data field of the snapshot information dataset;format the set of statistics; andoutput the set of statistics, wherein no snapshot information used to compute the statistics is directly outputted.
