Configuring Exabeam Data Services Data Retention in Exabeam Data Lake

Hardware and Virtual Deployments Only


To configure this feature, please contact your Exabeam technical representative.

By default, the retention policy for Exabeam Data Services (EDS) data is 30 days. Therefore, LDIF (LDAP Data Interchange Format) files collected daily from the LDAP (Lightweight Directory Access Protocol) server(s) are retained for 30 days.

In general, the 30-day default period is suitable for the average customer and does not affect product behavior performance. However, some customers may need to reprocess older events, which may include events related to users or assets that are no longer active, and won’t be found in the current context tables. In this specific case, the events will be reprocessed but might not be able to leverage the historical contextual information.

To configure the EDS data retention period:

  1. Access the EDS custom application.conf file: /opt/exabeam/config/common/eds/custom/application.conf

  2. Add the value here, where N is the total number of retention days:

    EDS.Defaults.RetentionPeriod = N days
  3. Stop, and then start EDS again:


Re-Assign to a New IP (Appliance Only)

Hardware Deployments Only


These instructions apply to Exabeam appliances only. For instructions on re-assigning IPs in virtual deployments, please contact Exabeam Customer Success by opening a case at Exabeam Community.

  1. Set up a named session to connect to the host. This will allow the process to continue in the event you lose connection to the host.

    screen -LS [session_name]
  2. Enter the cluster configuration menu.

    source /opt/exabeam_installer/init/
  3. From the list of options, choose Change network settings.

  4. Choose Change IP of cluster hosts.

  5. Choose Change IP(s) of the cluster - Part I (Before changing IP).

  6. You will go through a clean up of any previous Exabeam installations.

    Do you want to continue with uninstalling the product? [y/n] y
  7. Acknowledge the Exabeam requisites.

    Part I completed. Nuke successful. Product has been uninstalled.
    Before running Part II, please perform these next steps below (Not optional!):
    - Step 1 (Manual): Update the IPs (using nmtui or tool of choice)
    - Step 2 (Manual): Restart network (e.g., systemctl restart network)
    Please enter 'y' if you have read and understood the next steps: [y/n] y
  8. Open the nmtui to change IP addresses of each host in the cluster where the IP address will be changed.

    sudo nmtui
  9. Go to Edit Connection and then select the network interface.

  10. The example below shows the menu for the network hardware device eno1. Go to ETHERNET > IPv4 CONFIGURATION.

    The menu for the network hardware device ​eno1​​, with the ​Ethernet and ​IPv4 Configuration sections highlighted with a red rectangle.


    Please apply the correct subnet CIDR block when entering [ip]/[subnet]. Otherwise, network routing will fail or produce unforeseen circumstances.

  11. Set the configuration to MANUAL, and then modify the IP address in Addresses.

  12. Click OK to save changes and exit the menu.

  13. Restart the network services.

    sudo systemctl restart network
  14. Enter the cluster configuration menu again.

  15. Choose Change network settings.

  16. Choose Change IP of cluster hosts.

  17. Choose Change IP(s) of the cluster - Part II (Before changing IP)

  18. Acknowledge the Exabeam requisites.

    Please make sure you have completed all the items listed below:
    - Complete Part I successfully (nuke/uninstall product)
    - (Manual) Update the IPs (using nmtui or tool of choice)
    - (Manual) Restart network (e.g., systemctl restart network)
    Do you want to continue with Part II? [y/n] y
  19. Provide the new IP of the host.

    What is the new IP address of [hostname]? (Previous address was[new_host_ip]
  20. Update your DNS and NTP server information, if they have changed. Otherwise, answer n.

    Do you want to update your DNS server(s)? [y/n] n
    Do you want to update your NTP server? [y/n] n

Exabeam Cluster Authentication Token

Hardware and Virtual Deployments Only

The cluster authentication token is used to verify identities between clusters that have been deployed in phases as well as HTTP-based log collectors. Each peer cluster in a query pool must have its own token. You can set expiration dates during token creation or manually revoke tokens at any time.

To generate a token:

  1. Navigate to Settings > Admin Operations > Cluster Authentication Token.

    admin operations cluster authentication token selection
  2. At the Cluster Authentication Token menu:

    cluster authentication token menu
    1. To configure a new token, click A blue circle with a white plus sign..

    2. Or to edit an existing configuration, click A pen shaped edit icon..

  3. In the Setup Token menu, fill in the Token Name, Expiry Date, and select the Permission Level(s).

    setup token menu


    Token names may contain letters, numbers, and spaces only.

  4. Click ADD TOKEN or SAVE to apply the configuration.

Use this generated file to allow your API(s) to authenticated by token. Ensure that your API uses ExaAuthToken in its requests. For curl clients, the request structure resembles:

curl -H "ExaAuthToken:<generated_token>" https://<external_host>:<api_port>/<api_request_path>
