1. A method for monitoring operations of a machine operating at a worksite, the machine being powered by an engine and including an implement for performing one or more of a loading operation and a dumping operation, the method comprising:
determining, by a processing unit using an engine speed sensor associated with the engine, a first parameter corresponding to an engine speed associated with the engine;
determining, by the processing unit using an accelerometer positioned inside an operator cabin of the machine, a second parameter indicative of vibrations detected inside the operator cabin;
determining, by the processing unit using a position sensor, a third parameter indicative of a machine speed associated with the machine; and
determining, by the processing unit, a machine operation as one of the loading operation, the dumping operation, and a travelling operation based on one or more of the determined first parameter, the determined second parameter, and the determined third parameter,
wherein the machine is configured to operate for a predefined time duration at the worksite to perform a plurality of loading operations, a plurality of dumping operations, and a plurality of travelling operations within the predefined time duration, and
wherein the method further comprises:
determining, by the processing unit, a time duration associated with completion of at least two of the plurality of loading operations, the plurality of dumping operations, and the plurality of travelling operations; and
generating, by the processing unit, a machine operations report indicating at least two of:
a first total percentage time of the predefined time duration, spent by the machine in performing the plurality of loading operations;
a second total percentage time of the predefined time duration, spent by the machine in performing the plurality of dumping operations; and
a third total percentage time of the predefined time duration spent by the machine in performing the plurality of travelling operations.
