Measures reported by MLXPGStatTest

Quality of Service (QoS) prioritizes network traffic and manages available bandwidth so that the most important traffic goes first. QoS is implemented as rules or policies that prioritize packets, optionally change information in the packet header, and assign them to outbound port queues based on their priority. The priority interface in Mellanox switch allows for the configuration of priority rules and handles the incoming traffic accordingly. The Mellanox swithc allows you to assign different traffic classes to a group where priority can be assigned to the whole group.

This test monitors the traffic and collects key stats about the priority treatment of grooups. Looking at the trend of these stats, the administrators can understand how the switch is behaving and if there are any issues.

Outputs of the test: One set of result for each switch.

Descriptor: Switch

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
RecvPkts Indicates the total number of packets received during the last measurement period belonging to the priority group. Number

If the number of messages and bytes is going down, there amy be a problem with either grouping or classification. You may want to look at stats from other tests to ensure there is no other problem.

RecvByte Indicates the total bytes received belonging to the priority group. MB

If the number of messages and bytes is going down, there amy be a problem with either grouping or classification. You may want to look at stats from other tests to ensure there is no other problem.

QDepth Indicates the total number of packets in the queue dedicated to priority group. Number

Priority group packets should be processed at priority so queue depth should be smallest as compared to other queues.
