Splunk® Add-on for OpenTelemetry Collector

Splunk Add-on for OpenTelemetry Collector

Troubleshooting

If you experience issues collecting data, try these steps to make sure that the Splunk Add-on for OpenTelemetry Collector is correctly deployed and configured.

If you confirm that the add-on is installed and configured correctly but you still can't see data in Splunk Observability Cloud, then the issue may be with your collector. See Troubleshoot the Collector in the Splunk Observability Cloud manual.

Verify that the Splunk Add-on for OpenTelemetry Collector is deployed successfully

  • Check your server to make sure it is adequately configured, refer to your OS documentation for more information.
  • Make sure that the Splunk Add-on for OpenTelemetry Collector is enabled in Settings > Forwarder Management > Add apps > Enable App.
  • Make sure that Splunkd has restarted after installation in one of two ways:
    • In the Splunk Web interface, you can check that the Splunk Add-on for OpenTelemetry Collector is enabled in Settings > Forwarder Management > Add apps > Restart Splunkd.
    • Check the Splunk_TA_otel.log to make sure that splunkd has restarted.

Verify that the Splunk Add-on for OpenTelemetry Collector is running properly

  • Check the following logs generated in $SPLUNK_HOME/var/log/splunk/ for any runtime or start/stop errors:
    • otel.log (or whatever you have named it to if using a custom log file)
    • Splunk_TA_otel.log
  • Make sure that there are no competing collector agents running on your server. If you have configured a collector agent using Splunk Observability Cloud, a new agent created on the same server with the Splunk Add-on for OpenTelemetry Collector will not run properly. See Manage Multiple Collectors for more information.
