We report a field-temperature phase diagram and an entropy map for the heavyfermion compound CeAuSb$_2$. CeAuSb$_2$ orders antiferromagnetically below$T_N=6.6$~K, and has two metamagnetic transitions, at 2.8 and 5.6~T. Thelocations of the critical endpoints of the metamagnetic transitions, which mayplay a strong role in the putative quantum criticality of CeAuSb$_2$ andrelated compounds, are identified. The entropy map reveals an apparent entropybalance with Fermi liquid behavior, implying that above the N\'{e}el transitionthe Ce moments are incorporated into the Fermi liquid. High-field data showingthat the magnetic behavior is remarkably anisotropic are also reported.
