The LHCb experiment started taking data with an upgraded detector in the Run 3 of the LHC, reading at 30 MHz full detector data with a software-only trigger system. In this context, live data monitoring is crucial to ensure that the quality of the recorded data is optimal. Data from the experiment control system, as well as raw detector data and the output of the software trigger, is used as input to the monitoring system. Plots of important quantities are delivered to the so called data manager shifter, present permanently in the control room. In addition, the same system is used to evaluate the quality of the data for future physics analyses. The presentation will describe the tools involved in the online monitoring: the infrastructure, the data processing, the plot visualisation applications and the various reporting tools available for experts to diagnose and follow problems arising during data taking.
