otelunifi — OpenTelemetry Output Plugin

Exports UniFi metrics to any OpenTelemetry Protocol (OTLP) compatible backend via push, using the Go OTel SDK.

Compatible backends include Grafana Alloy/Mimir, Honeycomb, Datadog (via OTel collector), Grafana Tempo, New Relic, Lightstep, and any vendor that accepts OTLP.

Configuration

The plugin is disabled by default. Set enable = true (or UP_OTEL_ENABLE=true) to enable it.

TOML

[otel]
  url      = "http://localhost:4318"   # OTLP HTTP endpoint (default)
  protocol = "http"                    # "http" (default) or "grpc"
  interval = "30s"
  timeout  = "10s"
  enable   = true
  dead_ports = false

  # Optional bearer token for authenticated collectors (e.g. Grafana Cloud)
  api_key  = ""

YAML

otel:
  url: "http://localhost:4318"
  protocol: http
  interval: 30s
  timeout: 10s
  enable: true
  dead_ports: false
  api_key: ""

Environment Variables

All config keys use the UP_OTEL_ prefix:

Variable	Default	Description
UP_OTEL_URL	http://localhost:4318	OTLP endpoint URL
UP_OTEL_PROTOCOL	http	Transport: http or grpc
UP_OTEL_INTERVAL	30s	Push interval
UP_OTEL_TIMEOUT	10s	Per-export timeout
UP_OTEL_ENABLE	false	Set to true to enable
UP_OTEL_API_KEY	``	Bearer token for auth
UP_OTEL_DEAD_PORTS	false	Include down/disabled switch ports

Protocol Notes

• HTTP (protocol = "http"): Sends to <url>/v1/metrics. Default port 4318.
• gRPC (protocol = "grpc"): Sends to <host>:<port>. Default localhost:4317. The URL for gRPC should be host:port (no scheme).

Exported Metrics

All metrics use the unifi_ prefix and carry identifying attributes (labels).

Example: Grafana Alloy

otelcol.receiver.otlp "default" {
  grpc { endpoint = "0.0.0.0:4317" }
  http { endpoint = "0.0.0.0:4318" }

  output {
    metrics = [otelcol.exporter.prometheus.default.input]
  }
}

Set UP_OTEL_URL=http://alloy-host:4318 and UP_OTEL_ENABLE=true in unpoller's environment.

Example: Grafana Cloud (OTLP with auth)

[otel]
  url      = "https://otlp-gateway-prod-us-central-0.grafana.net/otlp"
  protocol = "http"
  api_key  = "instanceID:grafana_cloud_api_token"
  interval = "60s"
  enable   = true
