Proton-proton collisions at the LHC can be classified as elastic,
non-diffractive, and diffractive. In this paper we discuss various measurements
of these above processes at various LHC experiments. We report about the total
proton-proton cross-section measurements, about the analysis of diffractive
events and also about the pseudorapidity distribution in inelastic events.Comment: 9 pages, 5 figures. Proceedings of the XLIII International Symposium
