Feature · Collector

Self-hostable collector for on-network capture.

Single Go binary inside your network. Local batching, on-disk buffering, redaction. Fans out to Trefur and any backends you already run, in parallel.

How it works.

The trefur collector is one Go binary. Run it on a host inside your network, in a Kubernetes sidecar, or as a systemd unit on a VM. Your SDKs point at it with the standard OTLP endpoints — /v1/traces, /v1/metrics, /v1/logs.

The collector batches locally, buffers to disk when the upstream drops, and replays cleanly when the network comes back. Redaction runs in the collector before egress — drop fields, mask substrings, hash identifiers — so sensitive content never leaves your perimeter unredacted.

The collector is fan-out friendly. Send traces to Trefur and any other OTLP backend in parallel. Keep your existing pipeline; add agent-aware observability without ripping anything out.

What you can do with it.

Single Go binary. No dependencies. Runs on Linux, macOS, Windows, ARM, x86.

Receives OTLP/HTTP and OTLP/gRPC at /v1/traces, /v1/metrics, /v1/logs.

Local batching with configurable size and flush interval.

On-disk buffering keeps data when the network drops; replays when it comes back.

Configurable redaction — drop fields, regex-mask values, hash identifiers before egress.

Fans out to Trefur and any other OTLP backend in parallel, including Datadog, Honeycomb, Grafana.
