CSS 11501 7.40 Monitoring the services on real servers?

[Marlon Malinao]

Hi,

Just want to ask some basic questions, How can i monitor the services (ie 80 and 443) of the real servers. So that when the CSS11501 detects that one of the services of one of the real servers is down, it will not forward the traffic to that server. Or is the CSS is configured to monitor the services by default?

Because we are planning to upgrade one of the webservers (web01) while web02 is running, if we shutdown the service 80 and 443, does it affect the end-user, will CSS automatically redirect it to web02?

Regards,

Marlon

keepalives configured for your services will mark the service down when its not available.

Hi Syed,

Thanks for the reply. No extra configuration needed and the LB will automatically route packets to the other server.
