Red Hat build of MicroShift

Select a medium configuration

You can configure MicroShift Observability to collect performance and resource information from various sources by updating the YAML file.

Procedure

Select a medium configuration by adding the following information to the /etc/microshift/observability/opentelemetry-collector.yaml file:

 receivers:
  kubeletstats:
    auth_type: tls
    ca_file: /var/lib/microshift/certs/ca-bundle/client-ca.crt
    key_file: /var/lib/microshift/certs/admin-kubeconfig-signer/openshift-observability-client/client.key
    cert_file: /var/lib/microshift/certs/admin-kubeconfig-signer/openshift-observability-client/client.crt
    insecure_skip_verify: true
    collection_interval: 10s
    endpoint: "${env:K8S_NODE_NAME}:10250"
    node: ${env:K8S_NODE_NAME}
    k8s_api_config:
      auth_type: kubeConfig
  k8s_events:
    auth_type: kubeConfig
  journald:
    units:
      - microshift
    priority: info
processors:
  batch:
  resourcedetection/system:
    detectors: [ "system" ]
    system:
      hostname_sources: [ "os" ]
exporters:
  otlp:
    sending_queue:
      storage: file_storage
    endpoint: ${env:OTEL_BACKEND}:4317
    tls:
      insecure: true
extensions:
  file_storage:
    directory: /var/lib/microshift-observability
service:
  extensions: [ file_storage ]
  pipelines:
    metrics/kubeletstats:
      receivers: [ kubeletstats ]
      processors: [ batch ]
      exporters: [ otlp ]
    logs/kube_events:
      receivers: [ k8s_events ]
      processors: [ resourcedetection/system, batch ]
      exporters: [ otlp ]
    logs/journald:
      receivers: [ journald ]
      processors: [ resourcedetection/system ]
      exporters: [ otlp ]
  telemetry:
    metrics:
      readers:
        - periodic:
            exporter:
              otlp:
                protocol: http/protobuf
                endpoint: http://${env:OTEL_BACKEND}:4318

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.

Restart MicroShift Observability to complete the configuration selection by entering the following command:
```
$ sudo systemctl restart microshift-observability
```
