OpenTelemetry output plugin

[BaptisteMeynier]

Hello everybody,

I use Fluentbit to redirect my Otel Data (trace, metric, log), for this I use OpenTelemetry output.

I have something like:

pipeline: outputs: - name: opentelemetry match: "*" host: otel-collector port: 4317 grpc: on

I need to enriched with some metadata on each scope (trace, metric,log), so I use processor with opentelemetry-envelope but also add_label.

`
pipeline:
outputs:
- name: opentelemetry
match: "*"
host: otel-collector
port: 4317
grpc: on
add_label: service_name my-service
processors:
logs:
- name: opentelemetry_envelope

      - name: content_modifier
        context: otel_resource_attributes
        action: upsert
        key: service.name
        value: my-service

`

So, data for logs and metrics are identic excepted underscore (opentelemetry-collector-contrib allow automatic convertion).

Do you know if this is possible to factorise this for all Otel scope ?

I find processor usage in this case quite heavy. Do you think that It should be good to create new keys inspired by add_label usage ?

Something like a key for each Opentelemetry context resource_attributes, otel_scope_name, etc (context from content modifier)
