ah looks like aggr nearly full messages are now lumped in with volume nearly full messages in Ontap 9, e.g:
*Message: monitor.volume.nearlyFull: Aggregate prod4a is nearly full (using or reserving 95% of space and 0% of inodes). * So I guess they are in there after all - that sorts me out.

I assume you got this message from trolling the message log?
yeah, that message has been around since the GX days I believe. sucks that it's gone in Ontap 9.

I'd probably just script something out that does a show aggr and then parses the numbers and alerts on them. 'dashboard storage show' might also be something to look at, but much harder to parse and work with.
yeah looks like will have to hack something together, would be great if the filer could tell you when it's running low on space though, seems like a pretty fundamental metric to be able to alert on.
Do you run with a bunch of small aggregates, or much fewer, larger aggregates? I personally like monster aggregates, so I don't have to move volumes very often if at all.
we thin provision all of our volumes, as it's difficult to forecast which ones will get large, and we don't want to have a lot of empty disk space wasted.
this means that aggregate used is fairly constantly rising, so once an aggr gets around 90% full, we start looking to vol move stuff elsewhere.
But I do have some smaller dedicated aggregates for some Oracle DBs which need the dedicated IOPs. This is still on a 7-mode 8.x system which is running out of steam...
