Logcore

Appearance

OpenTelemetry Collector ​

If you already run an OpenTelemetry Collector, or prefer one in Kubernetes, add Logcore as an exporter. Apps send to the Collector, and the Collector sends to Logcore.

Collector → Logcore directly ​

yaml
# otel-collector-config.yaml
receivers:
  otlp:
    protocols:
      grpc: { endpoint: 0.0.0.0:4317 }
      http: { endpoint: 0.0.0.0:4318 }

processors:
  batch: {}
  resource:
    attributes:
      - key: deployment.environment
        value: production
        action: upsert

exporters:
  otlphttp/logcore:
    endpoint: https://logcore.lsofito.com
    headers:
      x-logcore-api-key: ${env:LOGCORE_API_KEY}
    compression: gzip

service:
  pipelines:
    traces:  { receivers: [otlp], processors: [resource, batch], exporters: [otlphttp/logcore] }
    metrics: { receivers: [otlp], processors: [resource, batch], exporters: [otlphttp/logcore] }
    logs:    { receivers: [otlp], processors: [resource, batch], exporters: [otlphttp/logcore] }

To export over gRPC instead:

yaml
exporters:
  otlp/logcore:
    endpoint: logcore.lsofito.com:4317
    headers:
      x-logcore-api-key: ${env:LOGCORE_API_KEY}

Collector → Logcore agent ​

If the Collector runs on a server that has the Logcore agent with APM enabled, export to the agent. You don't need a key:

yaml
exporters:
  otlphttp/logcore:
    endpoint: http://127.0.0.1:4318

The Collector and the agent can't both listen on 4317 and 4318. Move one of them to other ports, for example otlp_http_addr: "127.0.0.1:14318" in logcore.yaml, and point the exporter there.

Kubernetes (Helm) ​

yaml
# values.yaml for open-telemetry/opentelemetry-collector
mode: deployment
extraEnvs:
  - name: LOGCORE_API_KEY
    valueFrom:
      secretKeyRef: { name: logcore, key: api-key }
config:
  exporters:
    otlphttp/logcore:
      endpoint: https://logcore.lsofito.com
      headers:
        x-logcore-api-key: ${env:LOGCORE_API_KEY}
  service:
    pipelines:
      traces:  { exporters: [otlphttp/logcore] }
      metrics: { exporters: [otlphttp/logcore] }
      logs:    { exporters: [otlphttp/logcore] }

Apps in the cluster then use OTEL_EXPORTER_OTLP_ENDPOINT=http://otel-collector.observability:4318 and no key.
