Hello,

Firstly, I am the load balancer monkey. So go easy on me when explaining sourceone !.

We have an F5 load balancer and have successfully load balanced what the storage guy tells me in the 'online' archive. Straight forward we have a VIP on the F5 that listens on port 80 and we then load balance it, with persistency, to a couple of backend servers on port 80 too. Work, marvellous.

There is this offline thing he wants, I am told this listend on tcp ports 8001 and 8002 and protocol is HTTP. So we create two VIPs, same IP address but the two different listner ports, we create two backend pools with the same server but with the two distinct listener ports.

The virtual server is marked as down, cause the pools are down.Fair, enough.

As a health monitor I have tried the basic GET \n/n and also GET / HTTP/1.1\r\nHost: \r\nConnection: Close\r\n. I have had to use that on some Oracle/Sun Java stuff before, the bog standard GET don't work.

Now I am not sure if I am meant to put a receieved string in.

If from the F5 I telnet to either port. I am making a connection and then being told to go away 'connect closed be remote host' etc

So, any documentatin / tricks / tips, anyone done this before ?

The web seems eerily quiet on this one.

Cheers,

George
