3.2. Configuring MicroShift Observability

Procedure

1. Update the /etc/microshift/observability/opentelemetry-collector.yaml file to specify an OTLP-compatible endpoint with the following information. The endpoint must link to an IP address or host name, and port number of an OTLP service.

   OTLP-compatible endpoint configuration

   # ...
   exporters:
     otlp:
       sending_queue:
         storage: file_storage
       endpoint: ${env:OTEL_BACKEND}:4317

       tls:
         insecure: true
   # ...
   service:
   # ...
     telemetry:
       metrics:
         readers:
           - periodic:
               exporter:
                 otlp:
                   protocol: http/protobuf
                   endpoint: http://${env:OTEL_BACKEND}:4318

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

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

2. Each time that you update the opentelemetry-collector.yaml file, you must restart MicroShift Observability to apply the updates.

   Restart MicroShift Observability by entering the following command:

   $ sudo systemctl restart microshift-observability
