Abstract: A method and system for performance management, wherein software applications processes run on one or more processors of monitored systems. One or more process collector monitoring processes retrieve performance measurements from the application processes and relay the measurements to a processor collector monitoring process on each processor. The former may aggregate the measurements based on various measurements' types, and sends the created performance scan data to a system collector server, that receives such performance scan data from a plurality of processors, alternatively performs further data aggregation and issues alarms based on predefined thresholds. Performance scan data is temporarily stored in a scan database, further sent under XML format to a file system repository, or accessible to consumers at requested time intervals.
