J-Flow v9 with two external flow collectors on SRX

Hi all,

I have configured J-Flow v9 on SRX according to this KB. I want to direct J-Flow traffic to 2 external collectors.

I have tried 2 external collectors under the same instance - instance1:

set forwarding-options sampling instance instance1 input rate 100
set forwarding-options sampling instance instance1 input run-length 0
set forwarding-options sampling instance instance1 family inet output flow-server X.X.X.X port 1111
set forwarding-options sampling instance instance1 family inet output flow-server X.X.X.X version9 template ipv4-test
set forwarding-options sampling instance instance1 family inet output flow-server Y.Y.Y.Y port 2222
set forwarding-options sampling instance instance1 family inet output flow-server Y.Y.Y.Y version9 template ipv4-test

But commit returned:

sampling inline configuration error
Can't configure inline output with more than one V9 collector configured

I have also tried 2 external collectors under different instances - instance1& instance2:

set forwarding-options sampling instance instance1 input rate 100
set forwarding-options sampling instance instance1 input run-length 0
set forwarding-options sampling instance instance1 family inet output flow-server X.X.X.X port 1111
set forwarding-options sampling instance instance1 family inet output flow-server X.X.X.X version9 template ipv4-test
set forwarding-options sampling instance instance2 input rate 100
set forwarding-options sampling instance instance2 input run-length 0
set forwarding-options sampling instance instance2 family inet output flow-server Y.Y.Y.Y port 2222
set forwarding-options sampling instance instance2 family inet output flow-server Y.Y.Y.Y version9 template ipv4-test

But commit returned:

sampling interface validation error
Can't configure multiple V9 samping instances

So can I have 2 external collectors on SRX or not ?

Thanks
