Error Reports
The final kind of report that GPA provides is the error report. The GPA Error Report
informs you of system errors and diagnoses them. There are two types of errors that
can occur:
• Fatal errors that cause GPA to terminate.
• Non-fatal errors, on which GPA bases its performance-enhancing
recommendations.
Example 4-47 is an example of an error report that contains both fatal and non-fatal
errors.
