Install the Machine Learning Toolkit
The Splunk Machine Learning Toolkit (MLTK) enables users to create, validate, manage, and operationalize machine learning models through a guided user interface. Use the following directions to install the MLTK on to your system(s).
In order to successfully run the Machine Learning Toolkit, the following is required:
- Splunk Enterprise 8.0 and above or Splunk Cloud Platform
- Installation of the correct version of the Python for Scientific Computing (PSC) add-on from Splunkbase.
- Installation of the Splunk Machine Learning Toolkit app from Splunkbase.
Choose the appropriate version of the Python for Scientific Computing (PSC) add-on for your environment:
On some Windows installations, installing PSC through the Splunk Manage Apps user interface results in an error. This error is usually benign and can be ignored. In some cases it is necessary to manually unpack the package in the apps directory to get past the error.

Splunk Cloud Platform deployments
Follow the appropriate directions for your instance of self-service or managed Splunk Cloud Platform.
Splunk Cloud Platform trial and self-service Splunk Cloud Platform
Install the Python for Scientific Computing add-on and the Splunk Machine Learning Toolkit app to your self-service instance of Splunk Cloud Platform using the app browser in Splunk Cloud Platform.
- Log in to your Splunk Cloud Platform instance.
- From the Splunk Web home screen, click on the gear icon next to Apps in the left navigation bar.
- Click Browse more apps.
- Search for the Python for Scientific Computing add-on and install it.
- Search for the Splunk Machine Learning Toolkit app and install it.
Managed Splunk Cloud Platform
Open a ticket with support and request the Python for Scientific Computing add-on and Splunk Machine Learning Tooklit app to be installed for you.
Splunk Enterprise single instance deployments
Follow these directions for single instance deployments.
Install the Python for Scientific Computing add-on and Splunk Machine Learning Toolkit app onto your single instance Splunk Enterprise
- Install the Python for Scientific Computing add-on first (required).
- Install the Splunk Machine Learning Toolkit app.
Install an app or add-on in Splunk Web
- In Splunk Web, click on the gear icon next to Apps in the left navigation bar.
- On the Apps page, click Install app from file.
- Click Choose File, navigate to and select the package file for the app or add-on, then click Open.
- Click Upload.
Install an app or add-on from the command line
At the command line, enter the following content, depending on your operating system.
./splunk install app <path/packagename>
splunk install app <path\packagename>
Alternatively, unpack/unzip the file then copy the app directory to
$SPLUNK_HOME/etc/apps on Unix based systems or
%SPLUNK_HOME%\etc\apps on Windows systems.
Splunk Enterprise distributed deployments
Follow these directions for distributed deployments.
Use the following tables to determine where and how to install the Splunk Machine Learning Toolkit and Python for Scientific Computing add-on in a distributed deployment of Splunk Enterprise. Depending on your environment, you may need to install the Splunk Machine Learning Toolkit and Python for Scientific Computing add-on in multiple places.
Where to install Splunk Machine Learning Toolkit and Python for Scientific Computing add-on
This table provides a reference for installing the Splunk Machine Learning Toolkit (MLTK) and Python for Scientific Computing add-on (PSC) to a distributed deployment of Splunk Enterprise.
Splunk instance type Supported MLTK required PSC required Actions required / Comments Search Heads Yes Yes Yes Install the MLTK and PSC add-on to all search heads where the Machine Learning Toolkit is used. Search heads must be running Splunk Enterprise 6.6 or greater. Indexers No No No Do not install on Indexers. Heavy Forwarders No No No These apps do not contain a data collection component. Universal Forwarders No No No These apps do not contain a data collection component. Light Forwarders No No No These apps do not contain a data collection component.

Machine Learning Toolkit files
You can view the source code for the Machine Learning Toolkit app in Unix and Windows environments:
- For Unix-based systems, see
- For Windows systems, see
The Machine Learning Toolkit is not open source and MLTK source code is provided as an example only, and for educational purposes.
Refer to the following table for sub-directory names and descriptions:
||Contains configuration and dashboard files.|
||Contains the sample datasets used in the Showcase examples, along with more information about the datasets and their licenses.|
Permanent model files, sometimes referred to as learned models or encoded lookups, are saved on disk. These files follow Splunk knowledge object rules, including permissions and bundle replication. Bundle replication is the process by which knowledge objects on the search head are distributed to the indexers.
The Machine Learning Toolkit includes a number of example model files that support the Showcase page. These examples are powered by .csv lookup files. To prevent performance issues, these .csv lookup files are not included in the MLTK bundle replication process.
