Manage Splunk UBA configuration properties in the uba-site.properties file

Configure Splunk UBA by adding or editing properties in the /etc/caspida/local/conf/uba-site.properties file. Customizations made in this file are not modified during any upgrade procedures.

You can configure the following product areas in Splunk UBA by adding or editing properties in the /etc/caspida/local/conf/uba-site.properties file:

In the tables in each section, the values in the Default behavior column indicate the default Splunk UBA behavior when a configuration property is not set.

How to set configuration properties in Splunk UBA

A file called /opt/caspida/conf/uba-default.properties is used by Splunk UBA to manage many of the processes and micro-services required to operate Splunk UBA. To edit any of these default properties, or to add new properties, copy this file to /etc/caspida/local/conf/uba-site.properties file. Only edit the uba-site.properties file when changes are required. The /etc/caspida/local/conf directory is not affected by any upgrade scripts so configuration changes in this location can persist across product upgrades.

Perform the following steps to edit the /etc/caspida/local/conf/uba-site.properties and have the changes take effect:

  1. Log in to the Splunk UBA management node as the caspida user.
  2. Edit the /etc/caspida/local/conf/uba-site.properties file and add or edit the desired property and value.
  3. Save and exit the file.
  4. Synchronize the configuration changes across the cluster:
    /opt/caspida/bin/Caspida sync-cluster  /etc/caspida/local/conf

Depending on the service you are configuring, there might be additional steps required in order for the configuration property changes to take effect.
