Exporting failed. Dropping data for host node logs

[ba1ajinaidu]

Describe the bug I'm trying to export the host level logs from a kubernetes node to quickwit using otel-collector, using filelog receiver to read /var/log/messages file and exporting it. But the logs exporting fails with below error logs

2024-03-15T17:10:37.980Z    error   exporterhelper/queue_sender.go:97   Exporting failed. Dropping data.    {"kind": "exporter", "data_type": "logs", "name": "otlp", "error": "not retryable error: Permanent error: rpc error: code = Internal desc = ", "dropped_items": 2}

Steps to reproduce install otel-collector with the below give helm-values and install quickwit with default helm values

What did you expect to see? Logs should be exported to quickwit

What did you see instead?

logs are not being exported and are dropped

What version did you use? 0.96.0

What config did you use? used helm chart to install collector

@ba1ajinaidu it looks like only your exporter is having trouble. Check that your endpoint/port is correct and available

[ba1ajinaidu]

@TylerHelmuth I checked endpoint/port both of them are correct and are working for other logs, it still fails for this file.

[TylerHelmuth]

Oh interesting. Can you add a debug exporter with verbosity: detailed to the pipeline and isolate it to only the troubled file?

And other logs flow through this pipeline to the same endpoint without issue?

Can you point your OTLP exporter to a otlp receiver in another collector (or another pipeline in this collector)? I want to make sure there isn't something in the data that isn't being handled correctly in OTLP (this is extremely unlikely)

[ba1ajinaidu]

Yes. Tried pointing the exporter to a receiver in a new pipeline, still seeing the same error

[bhavin-kotak]

Any resolution that you found for this error? I am getting same error when the exporter is tempo
