This section contains information on features that pertain to the Local-External Storage 
Server (L-ESS) and Remote (Long Term)-External Storage Server (R-ESS).

R-ESS introduces new configurables to selectively discard the insignificant UDRS in the 
database based on a threshold limit in the form of number of total bytes. The statistics of the 
discarded UDRs will be displayed in Summary Report. Discarding the insignificant UDRs 
will result in the reduction of the number of records in the database and improvement of the 
R-ESS reporting performance.

The R-ESS extends its support to include yet another configurable that is set accordingly to 
enable the collection of parsing statistics report.

This functionality allows the user to select multiple content types from GUI as well as CLI 
and enables the R-ESS to generate Threshold Content Type and/or Top N Content Type 
reports based on the selected types. This feature further enables the R-ESS to specify a 
combined threshold for the selected content types and view the list of users who have used 
the most amount of traffic for the content types.

The L-ESS application extends its support to include some new configurables that are set 
appropriately to pull the xDR files from ST-series platform and push the files to configured 
destinations. When this functionality is enabled, L-ESS will start the pull process and file 
transfer process simultaneously or separately based on the configurations. The L-ESS is 
configured in such a way that the files are accepted from ST-series platform and then 
pushed to a central location at L-ESS. The L-ESS pushes the files further to the 
destinations. The file transfer process will automatically detect the number of hosts and 
whether they are willing to push EDR / UDR files to L-ESS by detecting the directories 
present below the configured base path.

The L-ESS extends its support to include some new parameters in the configuration file, 
allowing the user to configure up to a maximum of four SNMP destinations for the traps to 
be forwarded.

Also, a script ‘addhosts.sh’ is modified for addition and removal of Starent and SNMP 
Manager hosts dynamically. This script is now menu driven and provides option for adding 
and removing these hosts.

For more information, see the ESS Installation and Administration Guide.
