This read-create flag turns J-Flow, Juniper's NetFlow-style traffic flow accounting, on or off for an IP interface built from this profile. Admins enable it when they need visibility into per-flow traffic statistics, such as source, destination, protocol, and byte or packet counts, for capacity planning, billing, or troubleshooting on that interface. For example, setting juniIpProfileFlowStats to enable on a profile causes every interface using it to start exporting flow records that a NetFlow collector can use to report top talkers.
