Yep.

We double check a providers service (to ensure access to it has not 
failed because of ISP failure) by having a service event handler ssh to 
another host - in a different administrative domain - and repeat the 
check from there.

exit 0
  unless $ARGV[1] eq 'HARD' ;

open(OUT, '>> 
/home/nagios/results_of_traceroute_and_check_qwebprd_on_foo')
  or die "Cannot open 
\"/home/nagios/results_of_traceroute_and_check_qwebprd_on_foo\" in 
append mode: $!" ;

select OUT ;

$| = 1 ;

print scalar localtime, "\n" ;

print qx'ssh stanley at foo.bar "perl/check_qwebprd; echo; 
traceroute -Picmp -q1 qwebprd.questel.fr" 2>&1' 

Event Handlers are very flexible.
 
You probably want to make sure that event handler self destructs if it 
hasn't finished in less than some maximum time interval.

'...No man is an island, entire of itself; every man is a piece of the
continent, a part of the main. If a clod be washed away by the sea,
Europe is the less, as well as if a promontory were, as well as if a
manor of thy friend's or of thine own were. Any man's death diminishes
me, because I am involved in mankind; and therefore never send to know
for whom the bell tolls; it tolls for thee...'

from Meditation 17, J Donne.
