3.6. Selecting a large configuration

Procedure

1. Select a large configuration by adding the following information to the /etc/microshift/observability/opentelemetry-collector.yaml file. Large is the default configuration.

     kubeletstats:
       auth_type: tls

   Replace the variable ${env:OTEL_BACKEND} with the IP address or hostname of the remote back end. This IP address resolves to the local node’s hostname. Any unreachable endpoint is reported in the microshift-observability service logs.
