Actual amount of Data transferred using SLP & AIR

I'm trying to find an easy way to report on the actual amount of data being transferred from one Netbackup 5220 appliance to another 5220 appliance using SLP & AIR.  Both appliances are running 7.6.0.2.  I wrote a script to look for the  "CR sent" field in the /usr/openv/netbackup/db/jobs/trylogs/ directory but as we implement Targeted AIR the script will have to be updated to accommodate the changes.  I could not find a report in OpsCenter that would give me this information.  Is the "CR sent" data logged somewhere other that the job logs that would make it easier to report on for any given timeframe?
