Nimbostratusrule choose different pool if primary one is down
Is there a way to have a rule automatically direct traffic to a different pool in the event that all the nodes in the primary pool fail? In this case my scenario is that the actual nodes are still up ...
Hi Steve --
Unfortunately, v4 doesn't offer us much in the way of checking the status of the pool before sending traffic to it. v9 is much more capable of handling this scenario.
The only way I can think to redirect traffic when the whole pool goes away while still keeping the same hostname would be to create another virtual server for the same name/IP, different port, then create a pool with the remote servers + SNAT & set the fallback URL to reference the new virtual server:
Existing vitual server: 10.10.10.1:80
Pool: normal server pool
Fallback: http://10.10.10.1:81
Fallback vitual server: 10.10.10.1:81
Pool: remote fallback server(s) + SNAT
