Hello, I have one question please....

I have 2 servers for loadbalancing, www page is working for everybody, but I still see total conns established=0, do you know why? Or how to check if load balancing is working? thx a lot

server1, serverfarm, state = OPERATIONAL

address = 1.1.1.1, location = <NA>

conns = 0, maxconns = 4294967295, minconns = 0

weight = 8, weight(admin) = 8, metric = 0, remainder = 0

total conns established = 0, total conn failures = 0

server2, serverfarm, state = OPERATIONAL

address = 2.2.2.2, location = <NA>

conns = 0, maxconns = 4294967295, minconns = 0

weight = 8, weight(admin) = 8, metric = 0, remainder = 0

total conns established = 0, total conn failures = 0

Hi,

Check if you are getting any connecitons to VIP using command below. You have options to filter with specific client ip too.

show module csm slot conns

Looks like the traffic is not passing through the CSM, hitting server directly? Do you access the VIP on CSM that loadbalances to the servers?

To loadbalance, you should access the VIP not the server directly.

Problem resolved. Thank you sivaksiv for your help. The problem was that I was connected to standby CSM :-).

Sorry for confusion.
