Identification of request families for measurements aggregation.
On performance report generation, requests are classified and aggregated on the basis of a generated key, resulting from the concatenation of fields type and comment of request reports.
To perform a smarter aggregation, a regular expression may be defined to represent a variety of such keys as a single family of request. Then an alias is given to identify this family of request.
Doing so results in a more relevant aggregation and in a more readable report.
Regular expressions follow Java's java.util.regex.Pattern format.
