Opentelemetry with Grafana cloud without agent

Monitoring and Observability Grafana
#1

Hi all! is there a way to use opentelemetry with grafana cloud, without having to install the grafana agent? We have an already existing open telemetry collector installed in our cluster

#2

(our tracing database) would probably be able to answer that for you

#3

In that case, just configure an exporter to forward the data to tempo in grafana cloud

#4

Something like this

 jaeger:
   protocols:
     grpc:

processors:
 batch:

exporters:
 otlp:
   endpoint: [tempo-us-central1.grafana.net:443](http://tempo-us-central1.grafana.net:443)
   headers:
     authorization: Basic <base64 data>

service:
 pipelines:
   traces:
     receivers: [jaeger]
     processors: [batch]
     exporters: [otlp]```

My setup on the otel collector matches this, but Im getting an unauthenticated desc error in the logs. I assume that this is down the to grafana API key being incorrect.
Outside of an API key with the “MetricsPublisher” role, what else needs done?

#6

Yes that is because you need to encode it using base64

#7

Give me a few minutes I have the steps for this somewhere

#8

echo -n "<your user id>:<your api key>" | base64

#9

So the api key is base64 encoded already, and that needs further encoded as above?
