Not being a python person I re-wrote Mark Ferlatte's script as a (very
crude)
simple shell script hack - emphasis on the hack.  Thanks to Mark for the
inspiration.

I changed the host-notify-by-epager command to the following:

# 'host-notify-by-epager' command definition
define command{
        command_name    host-notify-by-epager
        command_line    /usr/local/nagios/bin/hthrottle "$HOSTALIAS$"
"$HOSTSTATE$" "$OUTPUT$" "$DATETIME$" "$NOTIFICATIONTYPE$" "$HOSTNAME$"
"$HOSTSTATE$" "$CONTACTPAGER$"
        }

This calls this script:

#!/bin/sh
# Host throttle script designed to send a maximum of x pages (set in
variable $npages) every x minutes (set in variable $ctime - represented in
seconds, ie. 600 is 5 # minutes).

# Set Variables

hist=/usr/local/nagios/var/pagehist
ctime=600
npages=5
time=$( date +%s)
admin=nagios at localhost
tmp=/tmp/tmp$$

# Setup Temporary File

rm -f $tmp
touch $tmp

# Check for pagehist file

if [ -f $hist ]; then
    wait
else
    touch $hist
fi

# Purge entries older than x minutes from pagehist file

ttime=`expr $time - $ctime`

awk ' { if($0 > "'"$ttime"'") print $0} ' $hist > $tmp

mv $tmp $hist

# Have more than x pages been sent in the last five minutes - if yes then do
not send page.

pages=`echo \`wc -l < $hist\``

if [ "$pages" -ge "$npages" ]; then
        /bin/mail -s "More than $npages pages sent in the last five minutes"
$admin
else
        /usr/bin/printf "%b" "Host '$1' is $2\nInfo: $3\nTime: $4" |
/bin/mail -s "$5 alert - Host $6 is $2" $8
        echo "$time" >>$hist
fi

# Clean Up

rm -f $tmp
