OTel Collector
The OpenTelemetry Collector is LogClaw’s sole ingestion gateway. It accepts logs via OTLP (the CNCF industry standard) and forwards them to Kafka for processing.
Why OTLP?
OTLP is supported natively by every major observability vendor — Datadog, Splunk, Grafana, AWS CloudWatch, GCP Cloud Logging, and Azure Monitor. If your app already uses OpenTelemetry, point it at LogClaw and you’re done. No custom integrations needed.
Endpoints
| Transport | Port | Path | Use Case |
|---|
| gRPC | 4317 | — | High-throughput, binary Protobuf. Recommended for production SDKs and OTel agents. |
| HTTP/JSON | 4318 | /v1/logs | Human-readable JSON. Good for curl, scripts, and debugging. |
Both ports are exposed on the logclaw-otel-collector Kubernetes service.

Scaling
The OTel Collector supports horizontal pod autoscaling. For high-throughput deployments:
| Tier | Replicas | HPA |
|---|
| standard | 1 | Disabled |
| ha | 3 | Optional |
| ultra-ha | 5+ | Recommended (min 5, max 50) |
