Load balancer issue

Question

Hi Team,

 

I have a small confusion with the concept of load balancer.

Suppose, I have an application hosted in 4 servers and that is managed by a load balancer. Suppose, in a certain time, any one of the server got a high cpu, for which the server became unaccessable(not unreachable).

In such scenario, if the user tries to log in to the application, is it possible the load balancer may be redirect the user to the same server which was having a high cpu? or is it like this...the load balancer can understand or identify the server taking high cpu and redirect the user to the other server?

(do not consider the number of node connections for the servers, assume all are having an equal number of nodes connected to it)

 

Does cpu usage matters at all for the load balancer to redirect the user to the other server?

 

 

Thanks,
