nagios gives unknown state - when monitoring over WAN link

[Anthony Montibello]

You can always try using NSCA  with a very large timout,  If you are
already using NSCA for other things on you system you may want to run
a second one on a non default port that way you can set the timeout
specifically to handle the large lag time.  When using NSCA you would
basically run plugins on the remote servers and gather the outputs,
then send all the outputs at once via the send_nsca.

Make sure you adjust your timeout of whatever plugin you are using if
you are getting timeout or no data received from host in your
warnings.

Also you may want to change some of the service settings to prevent
the warnings
Read through the nagios Documentation on what the different service
settings do.

Hope this helps 
Tony
