The Gurobi Optimizer produces a log that allows you to track the progress of the optimization. The Gurobi command-line tool and the Gurobi Interactive Shell put the log to both the screen and to a file named gurobi.log by default. The other interfaces just put the log to the screen. Screen output can be controlled using the OutputFlag parameter, and file output can be controlled using the LogFile parameter.
