We would like n8n to offer easy integration with Observability & Evaluation platforms such as Langfuse and Comet Opik, which enable instrumentation of n8n workflows, be it a subset workflow or end to end.
I think each of these offer OTEL interfaces, which is a common open source standard for telemetry.
Apart from helping n8n users test, debug, and run evaluations on workflows, this critical missing piece would make n8n stand apart from competitor drag & drop builder offerings.
I’m part of the team at Comet, thanks for calling us out. We have actively started on an integration between Comet Opik with n8n. You can follow the issue on Github n8n Integration · langfuse · Discussion #4397 · GitHub
I would suggest to use OpenTelemetry to allow for interoperability with different observability and evaluation backends. Thereby, n8n users could configure their OTel endpoint and authentication in the UI (or as an env when selfhosting n8n) and it should just work.
