Predictive Analytics dashboard
Use the Predictive Analytics dashboard to search for different varieties of anomalous events in your data. Predictive Analytics uses the predictive analysis functionality in Splunk to provide statistical information about the results, and identify outliers in your data.
The Predictive Analytics dashboard filters are implemented in a series from left to right. Example: The Object filter is populated based on the Data Model selection. To analyze data with predictive analytics, choose a data model, an object, a function, an attribute, and a time range and click Search.
Use the available dashboard filters to refine the results displayed on the dashboard panels.
|Data Model||Specifies the data model for the search. Available data models are shown in the drop-down list.||Drop-down: select to filter by|
|Object||Specifies the object within the data model for the search. There must be a Data Model selection to apply an Object.||Drop-down: select to filter in|
|Function||Specifies the function within the object for the search. Functions specify the type of analysis to perform on the search results. For example, choose "
||Drop-down: select to filter in|
|Attribute||Specifies the constraint attributes within the object for the search.
Attributes are constraints on the search results. For example, choose "
|Drop-down: select to filter in|
|Time Range||Select the time range to represent.||Drop-down: select to filter by|
|Advanced||Access to the advanced predict options.||Link: A window of optional predict settings|
|Prediction Over Time||The Prediction Over Time panel shows a predictive analysis of the results over time, based on the time range you chose. The shaded area shows results that fall within two standard deviations of the mean value of the total search results.|
|Outliers||The Outliers panel shows those results that fall outside of two standard deviations of the search results.|
The Predictive Analytics dashboard is not restricted to any specific data source, but references data in any user selected data model. If the data model accelerations are unavailable or incomplete for the chosen time range, the predictive search dashboard will revert to searching unaccelerated, raw data.
Create a correlation search
From this dashboard, create a correlation search based on the search parameters for your current predictive analytics search. This correlation search will create an alert when the correlation search returns an event.
Click Save as Correlation Search... to open the Create Correlation Search dialog.
Select the Security domain and Severity for the notable event created by this search. Add a search name and search description. Click Save.
To view and edit correlation searches, go to Configure > General > Custom Searches. See the "Edit Correlation Search page" in the Installation and Configuration manual.
1. This dashboard references data from various data models. Without the applicable data, the panels will remain empty.
2. Use the Open in Search link available in the lower left corner of a dashboard view to perform a direct search against the data model. The New Search dashboard also exposes the search commands and objects used to populate the view.
3. Validate the data model is being accelerated.
- In the Splunk App for Enterprise Security, browse to Audit > Data Model Audit. Review the Acceleration Details panel for information about the data model acceleration status.
- Note: For more information about data model acceleration and the Enterprise Security App, see "Data models in the Enterprise Security app" in the Installation and Configuration Manual.
