Description
I am trying out Google Cloud and am trying to export OpenTelemetry traces from a test curl script on my laptop to Google Cloud. I can send data to the collector, but I consistently get the following response:
{ "partialSuccess": {} }
This indicates that my requests reach the server, but that the data isn't exporting. I don't see any results in my traces dashboard.
I also tried sending traces from a test Rust program I have on my machine, in case there was a problem with non-unique IDs being filtered. Nothing seems to export.
I can't seem to get any access to logs either. The OTel documentation says errors should be going to stderr but the collector doesn't report anything other than some startup info.
Steps to Reproduce
I followed these instructions to make sure the agent and service account are enabled and configured:
https://cloud.google.com/monitoring/agent/ops-agent/install-agent-vm-creation
https://cloud.google.com/stackdriver/docs/solutions/agents/ops-agent/otlp#config-overview
https://cloud.google.com/stackdriver/docs/solutions/agents/ops-agent/otlp#otlp-traces
I created a service key using the console option here:
https://cloud.google.com/iam/docs/keys-create-delete#iam-service-account-keys-create-console
I get version 0.123.0 of the googlecloud exporter from Docker
My Docker deploy:
docker run \
--hostname otel-collector \
--volume $(pwd)/gcloud_collector/service_acct_key.json:/etc/otelcol-contrib/key.json \
--volume $(pwd)/gcloud_collector/config.yaml:/etc/otelcol-contrib/config.yaml \
--env GOOGLE_APPLICATION_CREDENTIALS=/etc/otelcol-contrib/key.json \
--publish 127.0.0.1:4317:4317 \
--publish 127.0.0.1:4318:4318 \
--name google-otel-exporter \
otel/opentelemetry-collector-contrib:0.123.0
Test script:
curl -X POST http://127.0.0.1:4318/v1/traces \
-H "Content-Type: application/json" \
--data @trace.json \
--verbose
