MySQL Table Statistics not populating for 2TB Database

Hi, I have setup PMM as a docker container and am testing with database servers with varying sized databases. The MySQL table statistics is quite a useful feature, but it doesn’t seem to be populating for the largest databases, it does work fine however for the smaller databases which are less than half a terrabyte in size. So I am guessing some discivery queries are timing out for the larger ones.

Could someone please point out if there is a tweakable element here?
