Note:
The Pending Requests graph is not directly defined by metrics, but it is useful when considering
metrics. The Pending Requests graph presents the unit‐averaged number of requests that were
pending (in progress) at any moment of time. It allows you to correlate the number of requests
posted to a completer with other performance metrics.
10.18.4 Link Transaction Level Graphs
Memory Writes are the only (posted) requests that do not get promoted to the Split
transaction level. Therefore, Memory Write performance should be viewed at the Link
Transaction level. That is the reason graphs at the Link level only present the Memory
Write‐related metrics and are titled Writes: Response Time: and Writes: Throughput (see
the following figure).
