A system for generating a graphical display region indicative of a condition of a computing infrastructure, the system comprising: a server comprising a processor and a memory, wherein the memory includes code executable by the processor to execute: a configuration management database comprising nodes representative of at least one of an infrastructure resource or an applicative resource in the computing infrastructure; a data structure configured to store states of validity for nodes of the configuration management database; and a system management module configured to generate the graphical display region by executing instructions to: store alert data in an alert table of the data structure, the alert data corresponding to alerts relating to one or more nodes, each alert having a timestamp indicative of a first time at which it was identified; identify a plurality of valid alerts of the alerts stored in the alert table, based on the timestamp of each alert of the plurality of valid alerts being earlier than or coincident with an impact calculation start time; perform an impact calculation starting at the impact calculation start time to generate impact data for only the plurality of valid alerts, wherein the impact calculation determines an impact of the plurality of valid alerts on the computing infrastructure; and generate the graphical display region to display the impact data and alert data indicative of the plurality of valid alerts. a configuration management database comprising nodes representative of at least one of an infrastructure resource or an applicative resource in the computing infrastructure; a data structure configured to store states of validity for nodes of the configuration management database; and a system management module configured to generate the graphical display region by executing instructions to: store alert data in an alert table of the data structure, the alert data corresponding to alerts relating to one or more nodes, each alert having a timestamp indicative of a first time at which it was identified; identify a plurality of valid alerts of the alerts stored in the alert table, based on the timestamp of each alert of the plurality of valid alerts being earlier than or coincident with an impact calculation start time; perform an impact calculation starting at the impact calculation start time to generate impact data for only the plurality of valid alerts, wherein the impact calculation determines an impact of the plurality of valid alerts on the computing infrastructure; and generate the graphical display region to display the impact data and alert data indicative of the plurality of valid alerts. store alert data in an alert table of the data structure, the alert data corresponding to alerts relating to one or more nodes, each alert having a timestamp indicative of a first time at which it was identified; identify a plurality of valid alerts of the alerts stored in the alert table, based on the timestamp of each alert of the plurality of valid alerts being earlier than or coincident with an impact calculation start time; perform an impact calculation starting at the impact calculation start time to generate impact data for only the plurality of valid alerts, wherein the impact calculation determines an impact of the plurality of valid alerts on the computing infrastructure; and generate the graphical display region to display the impact data and alert data indicative of the plurality of valid alerts. <EOS>
