A full performance analysis of a complex computer system can be difficult to complete in a short time-scale if the system consists of many interworking sub systems, often widely separated geographically, and if time and budget pressures prevent the normal in-depth assessment of performance. There is, however, a way to identify performance problems and provide indications of where performance engineering effort should be directed to greatest effect - the performance health check. This chapter covers the full richness of the performance health check; normally a subset of the techniques would be employed, tailored to the particular requirements of the situation - time-scales often dictate how deeply the analysis should go. Note that the approach here concentrates on systems; networks would be covered in an analogous way.
