Reduction of alerts in information technology systems

A computer program product for dynamically reducing the frequency at which an information technology (IT) infrastructure automatically generates alerts, the computer program product comprising one or more computer-readable tangible storage devices and program instructions stored on at least one of the one or more computer-readable tangible storage devices, the program instructions comprising:

• program instructions to identify an opportunity to reduce a frequency at which the IT infrastructure automatically generates the alerts, the program instructions to identify the opportunity to reduce the frequency comprising program instructions to detect, using historical data from a plurality of data sources in the IT infrastructure, false alerts generated in the IT infrastructure;
• program instructions to generate a new alert policy that addresses the opportunity to reduce the frequency;
• and
• program instructions to perform a simulation of applying the new alert policy in the IT infrastructure using historical data from a plurality of data sources in the IT infrastructure.

A computer system for dynamically reducing the frequency at which an information technology (IT) infrastructure automatically generates alerts, the computer system comprising one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, the program instructions comprising:

• program instructions to identify an opportunity to reduce a frequency at which the IT infrastructure automatically generates the alerts, the program instructions to identify the opportunity to reduce the frequency comprising program instructions to detect, using historical data from a plurality of data sources in the IT infrastructure, false alerts generated in the IT infrastructure;
• program instructions to generate a new alert policy that addresses the opportunity to reduce the frequency;
• and
• program instructions to perform a simulation of applying the new alert policy in the IT infrastructure using historical data from a plurality of data sources in the IT infrastructure.
