I assume Splunk Cloud is supported?


  • Node.js v4 or later. Splunk logging for Javascript is tested with Node.js v10.0 and v14.0.
  • Splunk Enterprise 6.3.0 or later, or Splunk Cloud. Splunk logging for Javascript is tested with Splunk Enterprise 8.0 and 8.2.0.
  • An HTTP Event Collector token from your Splunk Enterprise server.

Could you please investigate this issue? Why is there a connection to

Kind regards,
