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
- Installation of the Python for Scientific Computing (PSC) add-on version 2.0.0, 2.0.1, or 2.0.2 from Splunkbase
- Installation of the Splunk Machine Learning Toolkit app from Splunkbase.
You can choose the appropriate version of the Python for Scientific Computing (PSC) add-on for your environment:
In order to save models, users need the
upload_lookup_files capability included in their role.
Specific version dependencies
For version information that includes MLTK, the PSC add-on, Python, and Splunk Enterprise, see Machine Learning Toolkit version dependencies matrix.
MLTK Version PSC Version 5.2.1 2.0.0, 2.0.1, or 2.0.2 5.2.0 2.0.0, 2.0.1, or 2.0.2 5.1.0 2.0.0, 2.0.1, or 2.0.2 5.0.0 2.0.0, 2.0.1, or 2.0.2 4.5.0 1.4 4.4.2 1.3 or 1.4 4.4.1 1.3 or 1.4 4.4.0 1.3 or 1.4 4.3.0 1.3 or 1.4 4.2.0 1.3 or 1.4 4.1.0 1.3 4.0.0 1.3 3.4.0 1.3 3.3.0 1.2 or 1.3 3.2.0 1.2 or 1.3 3.1.0 1.2
Versions 2.0.2 and 2.0.1 of the PSC add-on are limited to minor library upgrades from version 2.0.0. There are no differences in functionality to version 2.0.0 of the PSC add-on.
If you have written any custom algorithms that rely on the PSC libraries, upgrading to an updated version PSC library add-on will impact those algorithms. You will need to re-train any models (re-run the search that used the
fit command) using those algorithms after you upgrade the PSC add-on.

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 Yes No Conditional If you want to use the distributed apply feature of the MLTK, install the PSC add-on to all of your indexers. This feature is disabled by default. See Use your indexers to apply models. Indexers must be running Splunk Enterprise 6.6 or greater. The MLTK does not need to be installed on the indexers to enable this functionality. Heavy Forwarders Yes No No These apps do not contain a data collection component. Universal Forwarders Yes No No These apps do not contain a data collection component. Light Forwarders Yes No No These apps do not contain a data collection component.
Distributed deployment feature compatibility
This table describes the compatibility of the Splunk Machine Learning Toolkit and Python for Scientific Computing add-on with Splunk distributed deployment features.
Distributed deployment feature Supported Actions required Search Head Clusters Yes Search heads must be running Splunk Enterprise 6.6 or greater. Indexer Clusters Yes If you want to use the distributed apply feature of the Splunk Machine Learning Toolkit, install Python for Scientific Computing on the indexers in your cluster. This feature is disabled by default. See Use your indexers to apply models for information. Indexers must be running Splunk Enterprise 6.6 or greater. The Splunk Machine Learning Toolkit does not need to be installed on the indexers in your cluster to enable this functionality.
Use your indexers to apply models
If you have more than one Splunk indexer and want to take advantage of the parallel computing power available on your standalone Splunk indexers or Splunk indexing cluster, you can configure your indexers to run the
apply command, a CPU-intensive task that applies machine-learning models.
Follow these steps to use your indexers to apply model:
- Install the Python for Scientific Computing add-on on all of your indexers.
- On each search head in your deployment, open the local
mlspl.confconfiguration file in a text editor.
For Unix based systems:
For Windows systems:
mlspl.confin the local directory if one does not exist.
- Copy the
[default]stanza from the default
mlspl.confconfiguration file to the local version of the configuration file if this stanza is not present.
Location of default
mlspl.conffile on Unix based systems:
Location of default
mlspl.conffile on Windows systems:
- Change the
streaming_applycommand to be true as follows:
streaming_apply = true
Use the deployment methodology of your choice to make these configuration changes.

The MLTK is not open source. MLTK source code is provided as an example and for educational purposes only.
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.
