EES related measurements are used to measure the performance of an EES on each of the supported functionality.

Discovery procedures enable entities in an edge deployment to obtain information about EAS and their available services, based on specified criteria of interest. It is useful to analyse the EAS discovery success rate in order to assess EES performance. The discovery procedure may fail due to the unavailability of the relavant EAS. If the failure rate increases beyond a defined threshold, corrective actions (e.g instantiating the required EAS) can be taken by the OAM systems. Hence, it is necessary to collect measurement related with EAS discovery procedures. EAS discovery failure measurement can be used to mitigate the EAS discovery failure issue, based on the UE locations, application characteristics, and number of UEs that have failed in the EAS discovey during the EAS docsovery failure.

An EEC performs registration, registration update, and de-registration with an EES in order to provide information that can be used by the EES in Edge Computing services. It is useful to analyse the success rate of registration, registration update, and de-registration in order to assess EES performance. If the failure rate increases beyond a defined threshold, corrective actions can be taken by the OAM systems. Hence, it is necessary to collect measurement related with EEC registration, registration update, and de-registration procedures.

The EAS Registration procedure allows an EAS to provide its information to an EES in order to enable its discovery. It is useful to analyse the EAS registration success rate in order to assess EES performance. If the failure rate increases beyond a defined threshold, corrective actions can be taken by the OAM systems. Hence, it is necessary to collect measurement related with EAS Registration procedures.
