InfluxDB Exporter ExponentialHistogram Support

[IakMastro]

Hello,

I am using the InfluxDB OTEL Exporter to export metrics. However, I get this error:

024-11-07T09:47:49.183Z        error   internal/queue_sender.go:92     Exporting failed. Dropping data.        {"kind": "exporter", "data_type": "metrics", "name": "influxdb", "error": "not retryable error: Permanent error: failed to convert OTLP metric to line protocol: unknown metric type \"ExponentialHistogram\"", "dropped_items": 20}
go.opentelemetry.io/collector/exporter/exporterhelper/internal.NewQueueSender.func1

It is missing the ExponentialHistogram which I need to export.

This is my configuration:

  influxdb:
    endpoint: http://influxdb:8086
    timeout: 500ms
    org: xxxx
    bucket: metrics
    token: xxx
    metrics_schema: telegraf-prometheus-v2

I get the same error when the metrics_schema is set at telegraf-prometheus-v1. I am using this images: influxdb:2.7.10 and otel/opentelemetry-collector-contrib:0.112.0.

I am not sure if I haven't configured something or it's a bug/missing feature.

Cheers!
