The hot X-ray emitting interstellar medium of early type galaxies can be used in principle as a total mass tracer and a tool to determine the stellar orbital anisotropy, based on the hypothesis of hydrostatic equilibrium for it. Here the effects that deviations from equilibrium have on both estimates are shown, and a comparison is made with cases for which accurate optical and X-ray information are available.
