Probing to see if Varnish is Alive.

[Caunter, Stefan]

If your load balancer can do a port 80 check (or whatever port you are
using), you can block port 80 with pf to stop traffic flow, do your
updating, and return it to service by unblocking the port.

Hi,

 

Is there a way to probe a varnish server to see if it is alive ? We have
a couple of varnish servers that are load balanced. We would like the
load balancer to stop sending traffic to a particular varnish server if
we are updating that server. Is there a recommended way to do this ?

 

Thanks & Regards,

Mohan
