Before you start, read the prerequisites on the OTLP export page and check what is sent. This page only covers the values Bronto needs.
  1. Get the endpoint for your Bronto region. EU is https://ingestion.eu.bronto.io/v1/traces and US is https://ingestion.us.bronto.io/v1/traces. Checkly posts to exactly the URL you enter, so keep the /v1/traces path.
  2. Get the key. In Bronto, open Settings > API Keys, select Add API key, name it and give it the Ingestion Role. Copy the key right away, because Bronto shows it once. API Keys page in Bronto
  3. Paste the values into Checkly. On the Traces settings page, turn on Enable exporting traces, paste the URL, add the header below, and save. Checkly Export Traces settings with the Bronto endpoint and the x-bronto-api-key header
  4. Run a check, or wait for its schedule. Ad hoc runs from the check editor are exported too.
  5. Find the spans. In Bronto, open Tracing. The spans appear under service checkly, named after the check. Checkly span as the root of a trace in Bronto Tracing
If no spans arrive, check that the export is saved, that the header name is exactly x-bronto-api-key and that the key carries the Ingestion role. Then check the region: an EU key sent to the US host is rejected, and the other way round. When your own services are instrumented and report to the same Bronto account, their spans nest under the check run with no further setup. Correlate with your application’s traces covers the headers that make this work. Build conditions with Filter: pick the field Span:checkly.check.status, the comparison does not equal and the value PASSED to list the runs that did not pass, and add $service.name equals checkly to leave your own services out. Bronto trace filter for Checkly runs that did not pass Bronto documents the endpoints in Bronto Ingestion Endpoints and this setup in Checkly synthetic monitoring with OpenTelemetry. To see failed runs, filter on the attribute checkly.check.status with the value FAILED. The OTLP export page has the span schema.
