Is it possible to know the amount of data passing through an ASA firewall

I would like to identify data ex filtration through my Cisco ASA firewalls. Is this possible? Can you provide a sample query?

I'd try experimenting with the Splunk Add-on for Cisco ASA (https://splunkbase.splunk.com/app/1620/) since it appears that one of the metrics that maps to the Common Information Model (CIM) is 'Network Traffic'.

I don't currently have a Cisco ASA to test with, but this add-on may help to provide enough information to run a search against the network traffic fields such as 'bytes', 'bytes_in', or 'bytes_out'. Here is more information on the 'Network Traffic' data model for the Common Information Model.
