Monitoring a service if ICMP to the host isblocked

Hi all,

i've done the same for my loadbalancer-cluster. I use the HTTP-check as check_command in the hostconfig to ensure that the single nodes are up.

Kind regards,

Sure... either simply remove the host check from the hosts definition, 
or - what I would do - use the ftp check as a host check also.
