Prerequisites
Before you begin, make sure you have:- a Bronto API key
- an application instrumented with an OpenTelemetry SDK, or an OpenTelemetry Collector receiving traces
- network access to the Bronto ingestion endpoint for your region
Endpoint and authentication
Use the trace endpoint that matches your Bronto region:| Region | Trace endpoint |
|---|---|
| EU | https://ingestion.eu.bronto.io/v1/traces |
| US | https://ingestion.us.bronto.io/v1/traces |
Supported protocols
Bronto supports OTLP using:- gRPC on port
4317 - HTTP on port
4318 - HTTP OTLP on port
443
443 is the simplest option.
Send traces through an OpenTelemetry Collector
If you are using an OpenTelemetry Collector, configure an OTLP receiver and an OTLP/HTTP exporter that targets the Bronto trace endpoint.otel-config.yaml
<BRONTO_API_KEY> with your Bronto API key.
If your Collector also sends logs, keep traces and logs in separate exporters and pipelines. Traces use
traces_endpoint; logs use logs_endpoint.Send traces directly from an SDK
If you do not need a Collector, configure your application’s OpenTelemetry SDK to export traces directly to Bronto over OTLP/HTTP. For direct trace export, point your SDK at the regional traces endpoint and include the Bronto API key header:Minimal working examples
Bronto has OpenTelemetry setup guides for several languages. If you want a quick starting point, the Python and Node.js guides include complete working examples for logs and traces, including SDK setup, resource attributes, exporter configuration, and direct export to Bronto.Python
Configure the OpenTelemetry Python SDK, create spans, and export traces to Bronto.
Node.js / JavaScript
Configure the OpenTelemetry JS SDK, create spans, and export traces to Bronto.
Verify trace delivery
After configuration, verify trace delivery with these checks:- Confirm that you are sending traces to the correct regional endpoint.
- Confirm every request includes
x-bronto-api-key. - Run your application and trigger an operation that creates a span.
- Check Bronto for the expected
service.name. - Confirm new traces are visible and spans include the attributes you expect.
Troubleshooting
If you do not see traces:- verify the ingestion URL matches your region
- verify the
x-bronto-api-keyheader is present and valid - confirm your process flushes spans before exit
- confirm your exporter is configured for traces, not logs or metrics
- check network egress rules for ports
4317,4318, or443
Next steps
Once trace ingestion is working, you can:- add auto-instrumentation for your framework or runtime
- route telemetry through a shared OpenTelemetry Collector
- enrich spans with standard resource attributes
- standardize exporter configuration across services
