Auto detect log format, support ElasticSearch spans

Node.js3.7.2

Added

  • Add a log format option for autodetection the log format.
  • Add support for native OpenTelemetry spans from @elastic/transport package in Node.js.

Changed

  • Detect the log format automatically. We now detect if a log line is in the JSON, Logfmt, or plaintext format. No further config needed when calling our logger, like so:

    JavaScript
    const logger = Appsignal.logger("app"); logger.info("message");

Fixed

  • Fix 'unknown' events being reported for some HTTP routes.
