Abstract: A system to collect performance data and store it in a special data structure which records the metadata in the structure itself. The performance data for each day is recorded in time-series, converted into Unicode, and stored in a single directory. The performance metric data is compressed prior to transmission to a server over any data path. The data structure at the server where analysis is done has a subdirectory for every resource type. Each subdirectory contains text files each of which stores performance metric data values for a group of attributes with one section per attribute. The performance metric data values are recorded as a comma delimited list. Analysis of the performance metric data is done using regular expressions.
