I'm a 1.2 Luddite, but here's my $0.02.

Does the user running Nagios have access to /var/run/asterisk.ctl?

Using sudo will work. You could change the ownership or permissions of 
asterisk.ctl, but using sudo should survive upgrades better and has less 
chance of breaking something else.

FAILS is never used.

You don't need grep or cut. Since (I'm assuming) this script will run 
frequently, cutting the number of processes created in half seems like a 
good idea.

        STATUS=$(sudo asterisk -rnx "pri show span 1"\
                 | awk '/Status/ {print $3}'\
                 )

         if      [ "Up," == "${STATUS}" ]
         then    echo "PRI UP"
                 exit 0
         else    echo "PRI DOWN"
                 exit 2
         fi

Keep in mind that if the span has multiple D channels (like an NFAS group) 
you will get multiple statuses.

I'm not a big fan of using "-rx." I think AMI should be used for all new 
code.

Thanks in advance,
