Hi All, I have started to do monitoring of some hosts which are behind the firewall and PING (ICMP) is block on firewall. so I have exculded ping service in localhosts.cfg file and as well as check-host-alive option also from host template but still Nagios web interface shows host as "DOWN" RED Color in host status web interface. I think this is happening due to PING block on firewall. However ssh and nrpe port are opened on firewall to do monitoring of host resources. other services are showing OK in green color associate to this host. Please let me know how can we enforce nagios to shows that HOST is UP in host status web interface.
