UF sending data in LB fashion

[nikhilmehra79]

I have following config in my output.conf

[tcpout]
defaultGroup = productionSplunk1, productionSplunk2

[tcpout:productionSplunk1]
server = X.X.X.X:9997

[tcpout:productionSplunk2]

server = Y.Y.Y.Y:9997

I have search head and 2 indexers (x.x.x.x) and (y.y.y.y), when i now look in search head i am gettign double events , eg say UF send 2 events, i am getting 4 at search head - 2 from each of above indexers.

I expected the UF to send data to me in LB fashioned. Which is what it is not doing, any idea what is bad with my config

It is my config file. 1 minute at intervals will then load balance.

my output.conf
[tcpout]
defaultGroup = LB_indexers

[tcpout:LB_indexers]
disabled = false
autoLBFrequency = 60
server = x.x.x.x:9997,y.y.y.y:9997

I was referring to this URL.

http://docs.splunk.com/Documentation/Splunk/5.0.5/Deploy/Configureforwarderswithoutputs.confd

I think whether this serves as a reference.

Do you really need?

[tcpout] defaultGroup = LB_indexers

[nikhilmehra79]

i am trying now this - does this look fine?
[tcpout:my_LB_indexers]
server=X.X.X.X:9997,Y.Y.Y.Y:9997

Thanks , qq - what is significance of 1 minute - does it tell UF to send data 1 minute apart ?
