Definitive diagnostic data

Definitive diagnosis data are specific to the type of data used in the investigation and diagnosis of IT system problems; Transaction performance, fault / error or incorrect output.

Qualification

To qualify as Definitive Diagnostic Data it must be possible to correlate the data with a user’s experience of a problem, and for that reason they will typically be stamped event information. Log and trace records are common sources of Definitive Diagnostic Data.

Statistical data

Generally, statistical data can not be used as it lacks the granularity necessary to directly associate it with a user’s experience of a problem instance. However, it can be modified by reducing the time interval of the system.
