What do these symbols mean?

Do you know what do these symbols mean?
what information can I get from the picture?

solver: sdpt3

solver: Mosek

The only thing you should pay attention to in the SDPT3 output you show is the final Status reported by CVX.

Better yet, follow the advice in CVXQUAD: How to use CVXQUAD's Pade Approximant instead of CVX's unreliable Successive Approximation for GP mode, log, exp, entr, rel_entr, kl_div, log_det, det_rootn, exponential cone. CVXQUAD's Quantum (Matrix) Entropy & Matrix Log related functions . In your case, the advice is to use Mosek (and not used CVXQUAD).

As for the Mosek output, read the Mosek documentation. You are better off using Mosek than using SDPT3, the latter of which causes CVX’s unreliable Successive approximation method to be used.
