Enabling per-session accounting for offloaded NP6 sessions
By default FortiOS does not record log messages for offloaded NP6 and NP4 sessions. This also means that traffic monitoring does not report correct session counts, byte counts and packet counts.
However, for NP6 processors you can use the following command to enable per-session accounting for each NP6 processor in the FortiGate unit.
For example, to enable session accounting for the first and second NP6 processors (np6_0 and np6_1):
config system np6
edit np6_0
set per-session-acounting enable
next
edit np61
set per-session-acounting enable
end
