The open telemetry collector is used to receive, process, and deliver open telemetry traces to a backend.
|
|
There are many backends that can be used by setting "exporter" configurations.
|
|
The example configuration in the repository sends data to [Honeycomb.io](https://honeycomb.io) since they provide a free plan with 50,000,000 events per month.
|
|
See the values.yaml file for an example configuration and reference the [Open Telemetry docs](https://opentelemetry.io/docs/collector/configuration/) for additional options.
|
|
|
|
Be sure to replace all configurations in the values file which are encased in double brackets like `[[something]]`.
|
|
The example below has many different telemetry system configurations for example purposes.
|
|
Most people will have only one telemetry backend, though the example shows how to send to multiple.
|
|
If you do not wish to use a service, for example to remove NewRelic delete the exporter called `otlp/newrelic` and then remove pipeline `traces/2` which sends to that exporter and remove the `otlp/newrelic` exporter from the metrics pipeline.

To get the secret for troubleshooting, you can use a command like:
|
|
|
|
```bash
|
|
kubectl get secret -A --selector=configsecret=otelcollector -o go-template='{{range .items}}{{"----\n# "}}{{ .metadata.name }}{{"."}}{{ .metadata.namespace }}{{":"}}{{"\n"}}{{.data.otelConfigFile|base64decode}}{{end}}'
|
|
```
