To enable event visualization:
Log in to the Sentinel server as the novell user.
Open the <sentinel_installation_path>/etc/opt/novell/sentinel/config/configuration.properties file.
(Conditional) If you are using Sentinel in High Availability (HA) mode, ensure that the sentinel.ha.cluster property is set to true for all the nodes on the cluster.
Set the eventvisualization.traditionalstorage.enabled to true.
NOTE:Enabling or disabling event visualization generates an exception, as it restarts Sentinel indexing services. You can ignore this exception.
