The default host check is check_ping with some mildly liberal 
thresholds.  If you look for the host check command in your config 
files, you'll probably find a 50-100ms threshold pre-configured.  If 
your hosts are across the public Internet, sometimes those values will 
need adjusted.  Your host status page should tell you what the actual 
round trip time is as a basis for choosing the correct values.
