Endpoint

The Endpoint data model replaces the Application State data model, which is deprecated as of software version 4.12.0. The architecture of this data model is different than the data model it replaces. Each data set is directly searchable as DataModel.DataSet rather than by node name.

The fields and tags in the Endpoint data model describe service or process inventory and state, such as Unix daemons, Windows services, running processes on any OS, or similar systems.

Note: A dataset is a component of a data model. In versions of the Splunk platform prior to version 6.5.0, these were referred to as data model objects.


Dataset name Tag name

|____ Ports

|____ Processes

The following table lists the extracted and calculated fields for the event datasets in the model. Note that it does not include any inherited fields. For more information, see How to use these reference tables.

Search Example

The Endpoint data model is not directly searchable. Searching the Endpoint data model directly may show the following error: "Error in 'DataModelCache': Invalid or unaccelerable root object for datamodel." Instead, search for one or more of the data sets within the Endpoint data model: Endpoint.Ports, Endpoint.Processes, Endpoint.Services, or Endpoint.Filesystem.

An example follows for the new versus old search for summary count of ports by destination port:

Endpoint

| tstats `summariesonly` count from datamodel=Endpoint.Ports by Ports.dest

Application State

| tstats count from datamodel=Application_State.All_Application_State where nodename="All_Application_State.Ports" by All_Application_State.dest
