1. A method for optimizing event alerts in an information technology (IT) infrastructure management system, comprising: tracking, by a processor of an alert optimization system, one or more event alerts, triggered by monitoring tools, in the IT infrastructure management system; determining, by the processor, a probable usage for at least one configuration item associated with the one or more event alerts based on the tracking; determining, by the processor, a probable threshold value for each of the at least one configuration item based on the probable usage and capacity data; computing, by the processor, a final threshold value for each of the at least one configuration item based on at least one of the probable threshold value, seasonality data, or semantic context data; and optimizing, by the processor, the event alerts by filtering at least one unwanted event alert from the one or more event alerts based on the final threshold value.
