Netflow support for Brocade Vyatta routers


(Amir Gohar) #1

can logstash plugin for netflow support vyatta routers as well ?
i am able see my CISCO devices data on elk stack but not able to see the vyatta routers related data, i am aware of the supported exporters list that netflow plugin supports.

Currently VYATTA isn't supported, how hard it is to add support for VYATTA devices or what steps should be taken in order to support it ?

There were issues with older versions of the netflow codec, due to the MPLS Label Stack Octet related fields that are part of the Flow record sent by Vyatta (and VyOS) routers. It has worked fine since around November of last year. I use it with two VyOS routers as well as a Ubiquiti EdgeRouter (also a Vyatta community fork). What version of Logstash, or rather the netflow codec, are you using?

set system flow-accounting netflow timeout expiry-interval '60'
set system flow-accounting netflow timeout flow-generic '10'
