Most sourcetypes contain DNS events of some sort. This app provides Splunk dashboards, forms, and reports which can be used to explore your DNS events across your different sourcetypes.
To do this, the app relies on the Splunk Common Information Model (CIM) for network resolution (DNS) events. This means that the app can report on any network resolution(DNS) data, as long as it has been on-boarded properly, and is available through the Network Resolution (DNS) data model.
This app requires data model acceleration, which will use additional disk space. If you are using the Splunk App for Enterprise Security, this is already enabled, and should have been factored into your retention policies. If not, you should review the documentation on data model acceleration, how it uses disk space, and how to plan for it.
As mentioned above, the app uses the CIM for network resolution (DNS) events. The CIM allows you to take events from a number of sources or products, and report on them in one cohesive manner, using a common set of names for fields and event types.
Provides a starting point for exploring your DNS events. Most panels will drill-down to other pages in the application.
DNS events which appear to come from a single source.
DNS events sent to a specific destination.
DNS query information for specific queries.
Information about the sourcetypes which are present in the accelerated data.
This dashboard provides field information from the data models used to retrieve data for this application. Included information includes indexes and sourcetypes found in the data model. This dashboard also shows fields and constraints in the data models.

Because this App runs on Splunk Enterprise, all of the Splunk Enterprise system requirements apply.
This app depends on data models included in the Splunk Common Information Model Add-on, specifically the
Network_Resolution data model. Please review the information on installing and using the Splunk Common Information Model Add-on and information on configuring the acceleration on the data model.
The Splunk Common Information Model Add-on can be downloaded from Splunkbase.
This app has been tested with versions 4.15 of the CIM add-on.
In order to make the app respond and load quickly, accelerated data models are used to provide summary data. For this data to be available, the
Network_Resolution data model must be accelerated. Information on how to enable acceleration for the
Network_Resolution data model can be found here. The data model must be accelerated for the length of time for which you would like to see reporting.
Breakdown of Sourcetypes in Indexes in Dataset panel on the
Data Transparency Overview dashboard will only be seen if the
Sankey Diagram visualization is installed.
The Sankey Diagram Visualization can be downloaded from Sankey Diagram Custom Visualization.
