Tailoring diagnostic information specific to current activity of multiple threads within a computer system. A request to dump system state is received. A system dump is created, including main memory and system state information. The system dump is stored to a database. In response to a request to format the system dump, the system dump is loaded from the database, whereby a virtual memory image of system state at system dump time is created. The virtual memory image and system state information is scanned to identify tasks that were running, tasks that have failed due to an error, and tasks that were suspended at system dump time. State information and control blocks associated with the identified tasks are collected from the system dump and collated based on task number. The database is updated with a formatted system dump, including the state information and control blocks associated with the identified tasks.

Tailoring diagnostic information in a multithreaded environment

Generating a performance policy for a server. A plurality of system metrics of a first server is monitored, and a benchmark for the plurality of system metrics based on the monitored plurality of system metrics is stored. The benchmark indicates desirable system metrics of the first server. An operating policy for a second server is generated from the stored benchmark. The operating policy includes desirable system metrics of the second server based on the desirable system metrics of the first server.
