Statistics on the injection and beam availability in 2015 showed that too much time is spent at injection. Reducing this time could improve LHC availability and luminosity over the year. Currently, useful data to diagnose the problems is sparse and shown in different applications. Operators time is wasted in debugging and checking for the source of the problem before trying another injection. A new Software application for diagnostics of the LHC Filling is under development which collects data from multiple inputs of the CERN Control System and concentrates them in one central view. The inputs are processed and matched with a set of rules (or assertions) that need to be fulfilled for an injection to be successful. Whenever a problem occurs, the operator can check the Filling Diagnostic for hints on what is the source of the problem during the injection. Filling Diagnostic also produces statistics of the LHC injections and the causes of failed injections, this will allow significantly better analysis of the LHC performance for next year.
