Description

The CMS Online Monitoring System (OMS) aggregates and integrates different sources of information into a central place and allows users to view, compare and correlate information. It displays real-time and historical information.
The tool is heavily used by run coordinators, trigger experts and shift crews, to achieve optimal trigger and efficient data taking. It provides aggregated information for many use cases including data certification.
OMS is the successor of WBM, the Web Based Monitoring which was in use during Run 1 and Run 2 of the LHC.
WBM started as a small tool and grew substantially over the years so that maintenance became challenging. OMS was developed from scratch following several design ideas: to strictly separate the presentation layer from the data aggregation layer; to use a well-defined standard for the communication between presentation layer and aggregation layer; and to employ widely used frameworks from outside the HEP community.

A report on our experience of the operation of OMS for the first year of data taking of Run 3 in 2022 is presented.
