Description
This article explains how to set up the sample rate for Netflow.
Scope
FortiGate.
Solution
- NetFlow on FortiGate, exports all the information about sessions depending on netflow-sampler interface monitoring configuration.
- Netflow on FortiGate does not support the sampling rate below v7.6. sflow supports packet sampling at a configurable rate for all versions.
From v7.6.x onward the following CLI options can be used to control the sample rate:
config system interface
edit <interface name>
set netflow-sampler {tx | rx | both}
set netflow-sample-rate <integer>
set netflow-sampler-id <integer>
next
end
