MRTG can use shell commands as data source, so there is no problem
in monitoring any value you want. I get the queue size with:

n=`find /var/exim/spool/input -name '*-H' -print 2>/dev/null | wc -l`

Now I am sure that someone will again mention you how expensive that is.
It's not, unless the directory entries don't fit in your dentry cache,
but in that case you have a bigger problem than the above taking long.
I use this with queues up to >100k messages and it works just fine.
