Tandem Performance Data Collector (TPDC) Manual—526357-001
5-9
Data Communications Line Overview (DATACOM)
•
LID—specifies the Measure Load ID
•
SECTION—specifies the report section number
The chart is sorted in CPU number, channel, controller number, and then unit number
order.
Data Communications Line Overview (DATACOM)
This 74-column chart provides a tabular overview of communication lines other than
Expand lines. It includes:
•
A flag if retries occurred
•
Line name
•
Requests per second
•
Input bits per second
