An Ethernet metric system and methodology which provides comparable measurements over a data link layer for use in network engineering and Service Provider (SP) performance monitoring. The Ethernet metric system of the present invention utilizes a measurement appliance known as a nodal member for measuring various Ethernet and IP metrics. A plurality of nodal members is used to make one-way or round-trip measurements over asymmetrical paths. The system includes a database for storing measurement data recorded by the plurality of nodal members. A workstation is also contemplated to facilitate system configuration and reporting of measurement data. The system further includes at least one service daemon for interfacing between the plurality of nodal members and the database. Additionally, the service daemon instructs the plurality of nodal members to create vectors and obtain vector configuration from the database. The service daemon processes results data transmitted from the nodal members to the database.
