J-flow licensing on MX104

Hi,

 

maybe a dumb question but here goes :-)

 

I'm currently looking at some MX104 licensing and I'm not sure how to read the limitation for the 5G/10G J-flow licensing.

 

When looking at the description for S-ACCT-JFLOW-IN-5G the description is: "Flow monitoring and accounting features using J-Flow service on any MPC limited to 5G of total JFLOW traffic". (ref: http://www.juniper.net/documentation/en_US/junos15.1/topics/reference/general/mx-series-software-lic... )

 

My question: Is the 5G of JFLOW traffic defined as the amount of revenue traffic which is being sampled via the router or should it be read as 5G of sampled traffic, meaning you can sample 1/10 of your packets and then j-flow export 50G of revenue ttraffic?

 

If it's revenue traffic, can inline j-flow then be limited to only look at traffic to/from specific interfaces or is it per "MPC" (chassis in the MX104 situation).

 

Thanks in advance.
