Given a complex compact manifold $X$, we prove a Baum-Bott type formula for one-dimensional foliations on $X$, logarithmic along a hypersurface with isolated singularities. In this case, we show that the residues of the singularities of foliations can be given in terms of the Schwartz index. Furthermore, in this context, we proved that the Schwartz index is positive when $dim(X)$ is even, and that the GSV index is positive when $dim(X)$ is odd. We also obtained some applications in the context of the Poincar\'e's problem.
