Can the engines warn themselves about high vibrations or is it up to the crew to look at the gauges? I know the manufacturers have very advanced algorithms to detect wear/maintenance needs and so on, but how clever is the onboard software?
more like the ability of the detector and its mounting location to reliably detect (discriminate) all sources of vibration. We really don't want to introduce spurious unwarranted engine shutdowns, so we still rely on the pilot to use other senses as well.
