Confirm and troubleshoot DNS data collection

Check the indexer for data

After you configure and deploy the Splunk Add-on for Windows DNS into your DNS server, check the deployment server to see that data has arrived by loading the Search and Reporting app and view the Data Summary.

For an example of searches to use to confirm ingestion of Splunk Sample DNS searches and dashboards.

1. In the system bar, click Apps > Search & Reporting. Splunk Enterprise loads the Search & Reporting app.
2. Click Data Summary. Splunk brings up the data summary page with the "Hosts" tab active.
3. Scan through the list of host names for the name of your DNS server.
   
   If you do not see the deployment client host name, then there is a problem occurring between the client at the indexer. Confirm that:
   • You have properly configured receiving on the indexer.
   • You have properly configured the "send to indexer" app to forward data to the indexer.
   • No network issue exists between the deployment client and the indexer.
4. Click the host name in the list. Splunk Enterprise brings up a search window that displays all events associated with the deployment client host name.
5. Search through the data to see that all of the events you configured in the Splunk Add-on for Windows DNS have been sent to the indexer.
   
   If you do not see the events you expect, try these steps:
   • Confirm that you have placed the add-on in the deployment apps directory and reloaded the deployment server.
   • Confirm that the deployment client does not have errors attempting to collect the data.
   • More troubleshooting steps are available in the Splunk Troubleshooting manual.

What's next?

You have configured and deployed the Splunk Add-on for Windows DNS to your domain controller deployment clients. This now means that Active Directory data is present on the indexer. This is the last piece of the data puzzle.

The next step is to complete setup by finishing a few more required tasks.
