We have bash scripts that query the xml status pages for a given domain and looks for oldest message and queue size - it looks at all of the machines that we have in the cluster and then sends a mail message out if certain thresholds are exceeded. You can also query the xmlstatus pages and put together a page that indicates how many messages you have queued for the domains with the most mail - helpful if you have multiple machines and you need to know which domains that you need to be looking at for delivery problems.
Bash script to notify based on oldestmessage or queue size.
In the code below, you would need to change ownerlist, userpass, listofironports, and replace yourdomain.com with your domain name.
#!/usr/bin/bash
#--------------------------------------------------------
# This script checks on specified domains and attempts
# to send a message to warn a person if there are messages
# over 3600 seconds (1 hour) or more than 1,000 recipients
# in our queues for their domain. If the domain is down
# and the email address given to us is on their domain
# or forwards to their domain then it won't be delivered
# until their domain is back up.
# The script also saves historical data so we can look at
# it.
#--------------------------------------------------------
#--------------------------------------------------------
# Get the name of the script so we can send the output
# to the right place

To get the tophosts, you would do
statusinfo=`/usr/local/bin/curl -s -k https://$curironport/xml/tophosts -u "$userpass"--max-time 30`
and then parse out the hostname and active recipients.
