ⓘ Definitive diagnostic data

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

                                     

1. Qualification

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

                                     

2. Statistical data

Generally, statistical data cant be used as it lacks the granularity necessary to directly associate it with a users experience of a problem instance. However, it can be adapted by reducing the sample interval to a value approaching the response time of the system transaction being performed.
