Sure.  Take a look at the example (for restarting apache on a local
machine):

http://nagios.sourceforge.net/docs/1_0/eventhandlers.html

Now, configure a nagios account on the remote machine that has privileges
to run apachectl.  Create an ssh keypair and publish the public key in the
/home/nagios/.ssh/authorized_keys file.

Modify the stock event handler to do something like:

ssh -l nagios remote_box /usr/sbin/apachectl restart

Hope that helps.
