Global Indicators (COVER)
Global Indicators (COVER)
This 74-column report is a cover page for the set of charts and reports. It shows global
information, which includes:
•
The date and time of the measurement taken
•
The system measured
•
The numbers and types of CPUs
•
The total, average, low, and high values for key performance metrics
This report uses the GLOBINFO entity.
Parameters used are:
•
LID—specifies the Measure Load ID
•
SECTION—specifies the report section number
MEASURE Load ID: G1530MC1
