An information supply apparatus for a construction machine is adapted to enhance alarm/trouble cause checking accuracy. A user-side personal computer 4 or other apparatus, remote from a hydraulic excavator 1, acquires chronological data relating to alarm/trouble occurrence information on the hydraulic excavator 1, chronological data relating to engine on/off and engine key switch on/off information, and chronological data relating to operational-state physical quantities. The apparatus displays an item list of acquired alarm/trouble occurrence information, enables an operator to select first alarm/trouble occurrence information from the item list, automatically selects second alarm/trouble occurrence information with respect to the selected first alarm/trouble occurrence information, on the basis of a previously stored combination of alarms/trouble events which have some association with probable causes, and displays the chronological data relating to the thus-selected alarm/trouble occurrence information, together with the chronological data relating to the engine on/off and engine key switch on/off information.
