Version1.0.0
Minimum LogScale Version1.82.0

Enables parsing of DNS debug logs that contain DNS server information by the Windows Server.

Breaking Changes

This update includes parser changes, which means that data ingested after upgrade will not be backwards compatible with logs ingested with the previous version.

Updating to version 1.0.0 or newer will therefore result in issues with existing queries in for example dashboards or alerts created prior to this version.

See CrowdStrike Parsing Standard (CPS) 1.0 for more details on the new parser schema.

Follow the CPS Migration to update your queries to use the fields and tags that are available in data parsed with version 1.0.0.

Configurations and Sending The Logs to LogScale

Windows Logs Formats can be ingested using a log shipper Falcon LogScale Collector.

If the resulting logs include additional lines before the debug content the lines must be removed before the content is processed.

Installing the Microsoft DNS Debug Package in LogScale

Find the repository where you want to send the DNS debug logs, or create a new one.

  1. Navigate to your repository in the LogScale interface, click Settings and then Packages on the left.

  2. Click Marketplace and install the LogScale package for Microsoft DNS Debug.

  3. When the package has finished installing, click Ingest tokens on the left (still under the Settings, see Ingest Tokens).

  4. In the right panel, click + Add Token to create a new token. Give the token an appropriate name (e.g.the name of the server the token is ingesting logs for), and leave the parser unassigned. You can assign the parser to the LogScale Collector Configuration as described in the documentation Sources & Examples.

    Before leaving this page, view the ingest token and copy it to your clipboard — and save it temporarily elsewhere.

    Now that you have a repository set up in LogScale along with an ingest token you're ready to send logs to LogScale.

  5. Next, configure the Falcon LogScale Collector to ship the logs from your syslog server into LogScale. Follow LogScale Collector Install LogScale Collector and Configure LogScale Collector. LogScale Collector documentation also provides an example of how you can configure your syslog datasource, see Sources & Examples.

Verify Data is Arriving in LogScale

Once you have completed the above steps the DNS debug data should be arriving in your LogScale repository.

You can verify this by doing a simple search for #Vendor = "microsoft" | #event.module = "windows-dns"| #event.dataset := "windows.dns" to see your data.
