Support for the transform processor

[bmbferreira]

Is your feature request related to a problem? Please describe.

I'm using fluentbit to forward the logs to the opentelemetry collector and I want to parse the json from the logs and then transform some of the fields to attributes using the transform procesor. However that processor doesn't seem to be supported by the AWS otel collector.

Describe the solution you'd like

I would like to have support for the transform processor to be able to do advanced transformations using the Opentelemetry Transformation Language.

Describe alternatives you've considered

Use the docker image from opentelemetry instead of using this one from AWS.

Thanks for creating this feature request, certainly something we consider @bmbferreira. Please do note that at the moment we do not support logs GA in ADOT (see aws-observability/aws-otel-community#11 for details).

I would like to have transform processor for my trace processing - I would like to rename service.name attribute if it is not in allowed set, e.g.:

transform:
  error_mode: ignore
  trace_statements:
    - context: resource
      statements:
        - set(attributes["service.name"], "not-whitelisted-service") where isMatch(["service-a","service-b"], attributes["service.name"])

Thank you, @jangaraj

+1 to getting this processor added to ADOT. We are working with a customer for whom the lack of this processor is causing heartburn.

FWIW, I think this is a dupe of #1869. Very much hope it is picked up soon!

+1 for this processor, in the context of transforming histogram metrics for Dynatrace

Bumping this issue again.

I'd like to use this processor to extract attributes from a log's Scope, which doesn't seem to be possible with the processors currently included in the ADOT collector, but seems like it would be trivial with this processor:

transform/datadog/logs:
  error_mode: ignore
  log_statements:
    - context: log
      statements:
        - set(attributes["logger.name"], instrumentation_scope.name)

bump, this matters because the opentelemetry-shim adds links to every span and Honeycomb treats a link as an extra span in searches.

This feature is essential for efficiently processing message content towards CloudWatch. Having the transform processor would enable us to parse and filter logs effectively, allowing for better data management and more accurate insights. This capability is critical for creating efficient log filters and improving overall system observability. Thank you for considering this request.

+1 for this. Transform processor is useful not only for logs but also for traces. It provides functionality for traces that no other processor provides. Kindly consider this request to have transform processor support as a part of ADOT.

+100 This would be a very welcome feature.

Another use case is to manage attributes in metrics data points.
For example, taking Resource attributes and adding them as attributes in either Spans or Metrics data points.

Transform Processor is an essential component of OTEL Collectors. Its applicability extends to Traces and Metrics. I believe its currently the only way to inject OTEL Resource Attributes into Prometheus Labels Reference. An essential piece of functionality if you want to run a central ADOT collector and then inject deployment labels to Prometheus metrics.

I would love to see the Transform Processor included within the ADOT Collector package ❤️
