Sign-In logs when appearing offline?

Hi, I have been trying to access my Xbox activity logs (i.e., all the times my Xbox has been turned on) from the last couple weeks - it only shows up with my last two sign-in attempts, however. I appeared offline on Xbox, however, I figured this wouldn't stop me from accessing the actual sign-in logs in my account. Is this the case? If not, is there any way I can actually access my Xbox sign-in logs? It is a matter of safety, thank you for any help.
