Is it possible to have a script run in a loop (waiting for a change of state in the network interface), and if the loop continues for five minutes, to have it email the admin, and carry on in the loop?
Here is my loop:

io::async::signal
IO::Async::Signal(3pm) User Contributed Perl Documentation IO::Async::Signal(3pm)NAME
"IO::Async::Signal" - event callback on receipt of a POSIX signal
SYNOPSIS
use IO::Async::Signal;
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $signal = IO::Async::Signal->new(
name => "HUP",
on_receipt => sub {
print "I caught SIGHUP
";
},
);
$loop->add( $signal );
$loop->run;
DESCRIPTION
This subclass of IO::Async::Notifier invokes its callback when a particular POSIX signal is received.
Multiple objects can be added to a "Loop" that all watch for the same signal. The callback functions will all be invoked, in no particular
order.
EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_receipt
Invoked when the signal is received.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
name => STRING
The name of the signal to watch. This should be a bare name like "TERM". Can only be given at construction time.
on_receipt => CODE
CODE reference for the "on_receipt" event.
Once constructed, the "Signal" will need to be added to the "Loop" before it will work.
