Send logs

Rootprint accepts logs two ways:

OTLP HTTP: OpenTelemetry logs over HTTP (protobuf). Use it with any OpenTelemetry SDK, the OpenTelemetry Collector, or a sidecar that speaks OTLP. OTLP logs must go to an OpenTelemetry logs index such as otel-logs-v0_9 (see Index target).
NDJSON gateway: an authenticated HTTP endpoint that ingests NDJSON. Use it when you control the wire format and write to a custom-schema index.

If you have…	Use
An app in Python, Node.js, Go, or Zig	The matching language page (OTLP SDK)
Access logs from Caddy or Nginx	The matching web server page (OpenTelemetry Collector or Vector)
Container logs on a Linux host	Docker (Vector or OpenTelemetry Collector)
Pods in a Kubernetes cluster	Kubernetes (OpenTelemetry Collector DaemonSet)
Logs already on disk on a Linux host	OpenTelemetry Collector, Fluent Bit, or Vector
Existing pipeline that emits your own schema	NDJSON gateway
Syslog from Linux hosts or network appliances	Syslog (rsyslog + Vector)
An app in another language, or anything else that speaks OTLP	OTLP reference
