F5 pool troubleshooting

If few servers in .. F5 SERVER POOL are not working, then Connections will be dropped simply or Speed will be slow ?

anwers:

a.Connections will be droped if all servers related to application are behind that pool

b.Connection will be dropped if the pool is down as the VIP will be marked in a down state, make sure the health monitor port of pool on the physical server is opened !

c. connections should not be dropped and delay then depends on the volume of traffic hitting the VIP and LB menthod as well.we check  use of least connections and see.

d.Connection will not drop if you have applied monitor because it will mark them as unavailable and will not give the traffic to those server.You will can face some delay that will depend on the remaining server capability

e.If all servers are not down, then client traffic should redirects to available pool member so we should get performance issue if available server load is too high
