Hosts with multiple IP's + scheduling standard hosts

[mv652 at softhome.net]

Hi, 

I've searched the archive as well as online but couldn't find a concrete 
answer. 

How can I monitor hosts that have multiple IP Addresses? 

Currently we assign a 'virtual hostname' to each IP: 

IP Hostname_a
IP Hostname_b
IP Hostanme_c etc. 


I'm sure there muct be a simpler way. 


Secondly, I've seen posts that explain how to schedule checks and alerts for 
'critical' hosts with "NKTIME", but is there a way to schedule check of all 
hosts without adding them to a 'critical' list? 

We only want to check certain hosts 19:00 - 06:00 M-F for example. 


Thanks,
Mario
