Judging whether a small oil seep needs immediate work or monitoring

Safety-critical vehicle advice should be treated as general discussion; use qualified repair help when a fault could make a vehicle unsafe.

There's a slight oily film around a gasket, but no puddle under the car and the oil level hasn't noticeably dropped between checks. A mechanic mentioned it during routine service without saying it was urgent. I don't want to ignore an early warning, and I also don't want to pay for a large repair because a ten-year-old engine isn't perfectly dry. What photos, level checks or symptoms would make you move this from ‘monitor’ to ‘book the repair’?
