You can enable trackers like

\enabletrackers[figures.*]

But that just gives more log messages for debugging.

You get the list of all trackers with:

context --global m-trackers.mkiv


For your use case, directives are more helpful, like

\enabledirectives[logs.errors=*] (i.e. break at every error)

AFAIK that just handles missing characters, references and modules ATM, 
but this information might be outdated.

You get all directives with

context --global m-directives.mkiv
