The Spallation Neutron Source (SNS) accelerator systems are ramping up to deliver a 1.0 GeV, 1.4 MW proton beam to a liquid mercury target for neutron scattering research. Enhancements or additions have been made to several diagnostics instruments to support the ramp up in intensity, improve reliability, and/or add functionality. The Beam Current Monitors now support increased rep rates, the Harp system now includes charge density calculations for the target, and a new system has been created to collect data for the beam accounting and present the data over the web and to the operator consoles. Many of the instruments are PC-based and a way to manage their instrument configuration files through the Oracle database has been implemented. A new version for the wire scanner software has been developed and is under test. This paper also includes data from the various instruments.
