Anthropic's own telemetry failures no longer look like your collector breaking

Anthropic's own telemetry failures are summarised separately so they don't look like your collector breaking.

What

The wrapper around Anthropic's internal metrics exporter now reports success on every path, including shutdown, credential errors, opt-out check failures, HTTP failures and thrown exceptions, and routes the error to a new aggregator instead. The first failure logs a single line that says explicitly the problem is Anthropic's pipeline and not your own OpenTelemetry collector, later failures are counted silently, and a single summary line is emitted at flush or shutdown.

Details
  • Because the export is reported as a success, your OTel collector no longer sees these as export errors to retry or report.
  • Only the wrapper around Anthropic's own exporter is affected; a collector you configure yourself is untouched.
  • All log lines from this exporter gained a shared prefix so they can be told apart from your own pipeline's output.
  • Present unconditionally in this build, with no flag or setting controlling it.
Evidence

export failed (${e}). This is Anthropic's own telemetry pipeline, not your OTel collector; further failures are counted and summarised at shutdown., This is Anthropic's own telemetry pipeline, not your OTel collector; further failures are counted and summarised at shutdown.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
