Greetings from O-RAN-SC OAM.
Story:
We could validate and use successfully the VES collector version 1.10.1 for domain 'stndDefined'. In agreement with ONAP 5G SON use case team an OpenAPI3 yaml file was created as 'stndDefined' enhancement for [VES-PM-Streaming|https://gerrit.o-ran-sc.org/r/gitweb?p=scp/oam/modeling.git;a=blob_plain;f=data-model/oas3/experimental/o-ran-sc-du-hello-world-pm-streaming-oas3.yaml;hb=refs/heads/master] .
Basically we would like to transport a list of key/value pairs for Performance Measurement values. Due to the different nature of the PM-counter-values, the type of the 'value' can be one of several:
Please see line 140ff of the yaml file above:
[...] value: oneOf: - type: boolean description: A boolean value for the measurement. - type: integer description: A integer value for the measurement. - type: number description: A number value for the measurement. - type: string description: A string value for the measurement. description: 'The value of the measurement type for its period. ' [...]
Finding:
When sending a corresponding VES message the VES-Collector 1.10.1 reports in its logs:
docker logs -f ves-collector
[...]

Current workaround:
We modified the schema - all works fine, when the 'value' is of type 'integer' only.
value:
# oneOf:
# - type: boolean
# description: A boolean value for the measurement.
type: integer
description: A integer value for the measurement.
# - type: number
# description: A number value for the measurement.
# - type: string
# description: A string value for the measurement.
# description: 'The value of the measurement type for its period.
Such modification is used in O-RAN-SC E-Release for VES-Collector [configuration|https://gerrit.o-ran-sc.org/r/gitweb?p=oam.git;a=blob_plain;f=solution/integration/smo/oam/ves-collector/externalRepo/o-ran-sc/experimental/o-ran-sc-du-hello-world-pm-streaming-oas3.yaml;hb=refs/heads/e-release] .
Request:
Please support 'values' with 'oneOf' types.
