Monitoring in semiconductor manufacturing: A contribution to diagnosis in complex computer systems

Today´s computer environments move toward higher complexity. The expansion of the local networks, the need for heterogeneous software and hardware, and the various interfaces between them, bring new challenges into computer science. The requirements for availability and reliability 24 hours per day and 7 days per week let increase the system administrator´s effort needed. Highest flexibility and self organising raises the software overall performance and is taylored to the customer´s needs in the best way possible. However, it also raises a lot of new issues in the field of tracing, trouble-shooting and fault diagnosis.
