Telelemetry

Integration with Grafana Loki​

We can also configure the OTel collector to send logs to Loki backends. To do so:

  1. Export the collector config map into a file:

    kubectl get cm oblv-deploy-stack-oblv-deploy-chart-collector-config \
    		-n kube-system -o yaml > /tmp/collector-config.yaml
    	
    cat /tmp/collector-config.yaml

    apiVersion: v1
    data:
      collector-config.yaml: |
        receivers:
            otlp:
                protocols:
                    grpc:
                        endpoint: 0.0.0.0:4317
                    http:
                        endpoint: 0.0.0.0:4318
        exporters:
            debug:
                verbosity: detailed
        service:
            pipelines:
                traces:
                    receivers: [otlp]
                    exporters: [debug]
                metrics:
                    receivers: [otlp]
                    exporters: [debug]
                logs:
                    receivers: [otlp]
                    exporters: [debug]
    kind: ConfigMap

  2. Edit the config map to configure Loki as an exporter:

    apiVersion: v1
    data:
      collector-config.yaml: |
        receivers:
            otlp:
                protocols:
                    grpc:
                        endpoint: 0.0.0.0:4317
                    http:
                        endpoint: 0.0.0.0:4318
        exporters:
            debug:
                verbosity: detailed
            loki:
    				    endpoint: https://loki.example.com:3100/loki/api/v1/push
        service:
            pipelines:
                traces:
                    receivers: [otlp]
                    exporters: [debug]
                metrics:
                    receivers: [otlp]
                    exporters: [debug]
                logs:
                    receivers: [otlp]
                    exporters: [debug, loki]
    kind: ConfigMap

  3. Update the configmap:

    kubectl apply -f /tmp/collector-config.yaml -n kube-system

    configmap/oblv-deploy-stack-oblv-deploy-chart-collector-config configured

  4. Restart the OTel collector pod:

      kubectl rollout restart \
    	  deployment/oblv-deploy-stack-oblv-deploy-chart-collector \
    	  -n kube-system
    	
    	deployment.apps/oblv-deploy-stack-oblv-deploy-chart-collector restarted
