Upgrades to the Compact Muon Solenoid (CMS) system for the High-Luminosity Large Hardon Collider (HL-LHC) include the new Gas Electron Multiplier (GEM) detectors GE1/1, GE2/1, and ME0. The development of the GEM-Online Monitoring System (OMS) is crucial to their successful operation. The GEM-OMS provides real-time monitoring of key parameters, enabling the detection of anomalies by filtering data directly through different controllers. With a focus on improving efficiency and stability, the GEM-OMS offers a data visualization framework that facilitates easy interpretation of data through tables, graphs, and charts. This ensures the effective functioning of the upgraded muon system, contributing to the success of the physics program. This proceeding offers insights into the current status of the GEM-OMS, highlighting its most recent developments and advancements.
