QUESTION

Does Panther support OpenTelemetry (OTEL) logs? And how do I ingest them into Panther?

ANSWER

Panther does not officially support OTEL logs today, but you can ingest them with a few limitations and configuration adjustments.

You can send OpenTelemetry logs to Panther using an HTTP log source. However, Panther expects the endpoint to be provided exactly as configured, and cannot handle automatically appended paths such as /v1/logs.

Many OTEL exporters automatically append /v1/logs to the endpoint, which will cause ingestion to fail (404 errors).

Panther does not currently have built-in logic to interpret or normalize the OTEL log structure. As a result:

  • OTEL logs will be ingested, but they may appear unstructured or flattened.

  • If your logs look malformed or difficult to read, check if you can set the OTEL log exporter to use JSON encoding instead of the default protobuf (proto).

If you'd like Panther to support OTEL logs officially, please reach out to Panther support and raise a feature request.
