If you experience issues collecting data, try these steps to make sure that the add-on is correctly deployed and configured.

• Check your server to make sure it is adequately configured, refer to your OS documentation for more information.

• Check the log messages from the Collector by using the following Splunk query `index="_internal" Splunk_TA_otel | fields event_message.value` (assuming that the default logging configuration was not changed).

• Make sure that the Splunk Add-on for the 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, check that the Splunk Add-on is enabled in Settings > Forwarder Management > Add apps > Restart Splunkd.

Check the configuration of your OpenTelemetry Collector

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 might be with your collector instance. See Troubleshoot the Collector for further steps.
