The module version report provides information about the classes (modules) in the system, the versions of the modules, the update dates of the module versions, and the corresponding node ID. The report is provided in CSV format.
You can use this report to debug a system. The report helps to identify discrepancies in the system, differences in versions of modules across all the nodes, and problematic module versions. Knowing which module was not correctly loaded and on which node the module does not match the expected version, means that you can diagnose and solve the problem faster.
