j-flow monitoring on srx cluster - top talkers

[ Edited ]

Hello,

I would like to configure J-flow on SRX300 Cluster to monitor bandwith top users on PRTG.

It shows mixed traffic on PRTG since I have two outgoing connection one for Internet and one for WAN (Internal).

I already contacted PRTG and juniper support. JTAC says there is no option available in SRX series devices to check the top talkers with respect to interface. 

I would like to see top talker per interface. Do you have any advice?

 

Thank you very much.

netflow/jflow only generates per interface statistics that are sent to the analysis server.

 

the reporting engine to corolate and report on things like top talkers is a server function.  So if your current server does not have the reporting you are looking for you need to source other ones.

 

PC world has a convenient list and description of some open source options that you can see if they have the reporting you are looking for.
