Platform Installation for Splunk Cloud

Installation Requirements

Atlas for Splunk Cloud requires that a Splunk Search Head be deployed in your local environment that will connect to your Splunk Cloud environment. This Search Head must be configured as a Federated Search Head. Atlas will be installed on this Search Head and will connect to your Splunk Cloud environment. This Search Head will be referred to as the “Atlas Search Head” throughout the remainder of this article. Once deployed, you will add the Splunk Cloud Search Head as a search peer on your local Atlas Search Head to allow use of the Splunk REST command.

The Atlas Search Head Deployment Guidelines

  • Can be deployed in a clustered or non-clustered architecture or can also be an all-in-one (AIO) Splunk deployment
  • Must be deployed to an environment that is outside of your Splunk Cloud environment
  • Must be able to connect to Splunk Cloud over the internet (Typically over ports 8089, 8181, and 8191)

Installation Prerequisites

You should have obtained and completed the following items before proceeding with the installation:

  • A server that meets Splunk minimum requirements, has had Splunk installed on it, and meets the requirements set in “The Atlas Search Head Deployment Guidelines” section above
  • Administrative access to the Atlas Search Head’s Splunk web interface
  • The Atlas software
  • A valid Atlas license key
  • Administrative access to the Atlas Search Head
  • Created an “atlas_audit” events index on the Atlas Search Head
  • Created an “atlas_data_utilization” metrics index the Atlas Search Head
  • Created an “atlas_monitor_summary_metrics” metrics index the Atlas Search Head
  • Created an “atlas_stig_metrics” metrics index the Atlas Search Head

Atlas Search Head Sizing Requirements

Search head sizing guidance from Splunk

Splunk's sizing specifications can be found here. You should use these as your guidance for sizing your Atlas Search Head. The Atlas Expertise on Demand Team can be leveraged to provide you with customized guidance for achieving optimal Atlas performance in your environment.

Evaluation only Atlas Search Head Specifications

If you are evaluating Atlas, you can consider the following 'Evaluation only' specifications as minimum requirements for the Atlas Search Head. This should provide enough resources to evaluate Atlas features, but when you want to add production workload, you will need to comply with Splunk's recommendations.


The following specifications are Atlas software evaluations only. Do not use these server specifications for running production workloads.

  • An x86 64-bit chip architecture
  • 8 vCPU at 2Ghz or greater speed per core
  • 8GB RAM
  • 100GB of dedicated storage (SSD Based storage system with no less than 800 sustained IOPS, can be thin-provisioned)
  • A 1GB Ethernet NIC
  • A 64-bit Linux or Windows distribution

Configure the Atlas Search Head and REST Connections

Once you have installed and configured your Atlas Search Head you will need to connect it to your Splunk Cloud environment. If you are completing these items yourself, these steps are best executed using Splunk Cloud's Admin Config Service (ACS).

  1. Allow your Atlas Search Head's public IP on your Splunk Cloud Environment for REST API access.

    • This can be accomplished using the following methods:
      • ACS
      • Splunk server settings UI
      • Opening a request to Splunk Cloud support
  2. Configure Federated Search on the Atlas Search Head

    • Create an account on your Splunk Cloud instance with fsh_manage permission

    • On the Atlas Search Head, in Splunk Web, navigate to Settings -> Federated Search -> Add Federated Provider

    • Create a new Federated Provider in transparent mode using your Splunk Cloud URI and the account that was created above

    • See the Splunk documentation for more information on this topic

  3. Add the Splunk Cloud Search Head as a search peer on the Atlas Search Head

    • In Splunk Web on the Atlas Search Head, navigate to Settings -> Distributed Search -> Search Peers. Your indexers (both Splunk Cloud and local if applicable), should already be listed here.

    • Using the New Search Peer button on this page, add any other Splunk instances that you wish to be able to search or perform REST calls against.

      • Adding instances from your Splunk Cloud deployment requires the user credentials of a Splunk Cloud user with the role ofsc_admin
      • The search heads that you add, must be an equal or higher version than the search peers.

Atlas Platform Installation and Initial Configuration

The following procedure will outline the steps required to install the Atlas Platform on your local Atlas Search Head.

Installing Atlas Elements

Locate the Atlas Installer .tgz file (SA_atlas_installer-<version>.tgz) received when Downloading Atlas. Follow the guidance below for installing the application via the Splunk Web UI or CLI. The Atlas Platform Elements can then be automatically installed by running the installer script.

Splunk Web Upload

  1. Sign in as a Splunk Admin on your Splunk Search Head and navigate to Apps -> Manage Apps in the Splunk Web UI.

  2. Click on the Install App from File button located in the top right.

    Step 3

  3. Select the SA_atlas_installer-<version>.tgz file and Click "Upload". If you experience an issue, try selecting the “Upgrade App” checkbox when repeating the upload process. This option is required when upgrading to a new version of the Atlas Installer.

    Step 4


    You can confirm a successful upload of the file by searching “Atlas” on the Manage Apps screen, listing the Atlas Installer in Splunk's applications.

Splunk CLI Installation

  1. Using any available method, copy the application to an accessible directory on the Splunk Server where Atlas will be installed. The example below uses the scp utility.

    scp SA_atlas_installer-<version>.tgz
  2. Using any available method, access the CLI on the Splunk Server where the Atlas Installer has been copied. If applicable, become the Splunk service user.

  3. Run the Splunk CLI application installation command on the provided SA_atlas_installer-<version>.tgz. Adjust relative paths accordingly, or use absolute paths as documented. Address prompts for Splunk authentication as needed by providing valid credentials of a user configured with the admin role for the Splunk instance.

    # Where $SPLUNK_HOME is Splunk's home directory, e.g. /opt/splunk
    $SPLUNK_HOME/bin/splunk install app /tmp/SA_atlas_installer-<version>.tgz

Running the Atlas Installer Script

The Atlas Installer script must be run from the CLI. If the SA_atlas_installer application was installed via the CLI, skip to step 2.

  1. Using any available method, access the CLI on the Splunk Server where the Atlas Installer has been copied. If applicable, become the Splunk service user.

  2. The installer can be run without any arguments to guide an administrator through a series of prompts. The installation process can be customized by providing options detailed under Atlas Installer CLI Options. Basic usage of the installer script is shown below:

    # Where $SPLUNK_HOME is Splunk's home directory, e.g. /opt/splunk
    $SPLUNK_HOME/bin/splunk cmd python $SPLUNK_HOME/etc/apps/SA_atlas_installer/bin/
Atlas Installer Default Prompts

Running the installer script without any options will provide a series of prompts to modify the type of installation and confirm the resulting installation directories.

  1. In the first prompt, select the Deployment Type.

    Select Deployment Type:

    1 - Standalone Search Head
    2 - Deployer (SHC)
    3 - All in One

    Enter selection (1-3): 1
    • Standalone Search Head: This option installs the Atlas Elements to the $SPLUNK_HOME/etc/apps directory for use on the local Search Head. Any Elements requiring installation on additional Splunk Server types can be copied to the appropriate locations for manual installation (e.g. Cluster Manager for TA deployment to Indexers)

    • Deployer: This option installs the Atlas Elements to the $SPLUNK_HOME/etc/shcluster/apps directory, allowing admins follow standard deployment procedures to Search Head Clusters

    • All in One: This options installs the Atlas Elements to the same location as the Standalone Search Head option, $SPLUNK_HOME/etc/apps, while also copying any appropriate Elements to the $SPLUNK_HOME/etc/deployment-apps directory. This allows for the use of the All in One Atlas Server to push relevant Atlas configurations to Universal Forwarders with minimal configuration of the Deployment Server functionality.


      If no Elements in the acquired installation package are intended to be deployed by Deployment Server, the installation procedure for this option only deploys to the $SPLUNK_HOME/etc/apps directory.

  2. In the second prompt, confirm the installation paths based on the previous selection.

    Destination path(s):


    Proceed with installation? [y/n]: y
  3. Restart the Splunk service after the script completes.

    $SPLUNK_HOME/bin/splunk restart
Atlas Installer CLI Options

Run the installer script with the --help option to see additional details on setting deployment types without interactive prompts.

$SPLUNK_HOME/bin/splunk cmd python $SPLUNK_HOME/etc/apps/SA_atlas_installer/bin/
usage: Atlas Platform Installer [-h] [--install-type {local,deployer,aio}]
[--exclude {es,smh}]

This Supporting Add-on installs the Atlas Platform for Splunk.

optional arguments:
-h, --help show this help message and exit
--install-type {local,deployer,aio}
Target Splunk server type for installation.
--exclude {es,smh} Exclude special-use element sets.

Review Required Splunk Permissions & Capabilities

You must now ensure that user permissions are set correctly to ensure that you get the most out of Atlas. Instructions for setting these permissions can be found on the Atlas Capabilities & Permissions page.

Configure Atlas Audit

After the Atlas Elements have been installed and configured you should also configure Atlas Audit. Atlas Audit tracks activities performed by your users using Atlas. This information stays in your Splunk environment and can be used to track changes made to your Splunk deployment by your users using Atlas.

  1. Using your preferred method, create an index in Splunk with your desired name. The default is atlas_audit.

  2. The index used by Atlas Audit is specified in the atlas.conf file located at $SPLUNK_HOME/etc/apps/atlas_core/default/. You do not need to change anything in this file unless you plan to use a different index name. The contents of the atlas.conf file should look similar to the following:

    license_key =

    index = atlas_audit
    sourcetype = atlas_logs
    • Do not alter the sourcetype in the atlas.conf file. The sourcetype must remain atlas_logs for proper operation.
    • Do not edit the atlas.conf file in the /atlas_core/default/ folder. Any changes made there will be overwritten during an upgrade. Make any changes in the /atlas_core/local/ folder.
  3. Restart the Splunk Search Head to start capturing audit events.

ES Helper Configuration

If you are using the ES Helper Atlas Element, the are some additional steps required to properly configure the application. The ES Helper Atlas app requires an “ES” Distributed Search Group (DSG) to be created to facilitate communication with the ES Search Head.

  1. In the ES Helper app: Change the es_helper_target macro’s definition to “splunk_server_group=ES” if you have created an ES DSG, or “splunk_server=<ES Search Head server name>” if you have not, or if there is only one ES Search Head.

    • The server name can be found by running the following on the ES Search Head:

      | rest /services/server/info
      | table splunk_server
    • Navigate to Settings > Advanced search > Search macros, click the es_helper_target marco, edit the Definition field per the instructions above and Save.

    • Edit the es_helper_target macro

  2. Configure Data Model Acceleration:

    • Atlas ES Helper requires the Search Head where it is installed to define the same Data Models and Acceleration settings as the Enterprise Security Search Head.

      • Install Splunk_SA_CIM from Splunkbase and configure datamodels.conf in the $SPLUNK_HOME/etc/apps/Splunk_SA_CIM/local directory to match the same file on your Enterprise Security Search Head.
    • By default, Splunk Indexers create separate Data Model Summaries for each Search Head or Search Head cluster that defines a Data Model even if the definitions are identical. However, you can configure Splunk to use another Search Head’s Data Model summaries instead. Therefore, you should configure remote summaries to save indexer space and compute. Follow the following steps to configure a Remote Data Model Summary:

      • Ensure the ES Search Head has been added as a search peer on the Atlas Search Head.

      • To find the GUID of the ES Search Head, run the following search:

        | rest splunk_server=local /services/search/distributed/peers
        | table peerName title guid search_groups
      • In the $SPLUNK_HOME/etc/apps/Splunk_SA_CIM/local folder edit datamodels.conf. For each data model, add the following property:

        • acceleration.source_guid=<GUID from step ii>
      • Additional information about acceleration summaries can be found here
