The EMB has something similar LP & HP Vib display on the EICAS

The vibration monitor is an engine manufacturer function. Aircraft manufacturers using that function may call it by different names, even when using the same engine . While several factors can influence the vibration indication, it primarily monitors shaft bearing stability. Think of it as a compressor and turbine bearing health indicator.

It’s the High Pressure & Low Pressure Vibration Indicators on the EICAS.
the AE3007 A1 & A1/3 FADEC variants both provide the data,
it’s essentially begins life as a GE helicopter engine, and the last folks to bolt on their stuff is Allison/Rolls creating an AE3007.
The two most common FADEC versions are the A1 and the A1/3
good little engine.
