In the monit documentation I can see there is a check directory command but I can't see any examples of how to use it to see if the directory exists and if it doesn't to create the directory using the mkdir command.

This works for me:

check directory my_path path /mnt/some_mount_point
  if does not exist then exec "/usr/local/bin/create_mnt.sh"

This might help you mkdir -p $directory should do what you want. The -p option will create any necessary parent directories. If $directory already exists as a directory, the command does nothing, and succeeds. If $directory is a regular file, it will remain untouched, nd does not fail if the directory already exists, so you can do it all at once with:

mkdir -p /some/directory/you/want/to/exist || exit 1

Alec pretty much has it, but you don't need to create a script to do this. You can run mkdir directly (though note you need the full path to it):

check directory my_path path /mnt/some_mount_point
  if does not exist then exec "/bin/mkdir /mnt/some_mount_point"

Depending on your path, it may help to add the -p switch to mkdir if you need subfolders and/or duplicate error suppression.
