Introduction

The Filling-the-Gap (FG) module of the DICE Enhancement Tool is designed to achieve the following objectives:

Provide statistical estimation algorithms to infer resource consumption of an application.
Provide fitting algorithms to match monitoring data to parametric statistical distributions.
Annotate results in UML models.
Acquire data via JSON files, either user-specified or obtained from the DICE monitoring platforms (D-MON).

A high-level overview of the tool architecture is given in the figure below:

DICE-FG Architecture

The logical components of the DICE-FG tool are as follows:

DICE-FG Analyzer: Executes the statistical methods necessary to obtain the estimates of the performance models parameters, relying on the monitoring information available on the input files.
DICE-FG Actuator: Annotates in the UML model the parameters of the models, e.g., resource demands, think times, etc., which are obtained from the DICE-FG Analyzer.
