> After upgrading Ozone to a newer version, Recon faces compatibility issues while reading data from the GlobalStats table, that keeps a count of total records in every OM table and Size related metrics for certain OM tables. 
> The problem lies in the transformation of data values stored in the GlobalStats table between the old and new versions. The previous data format used a suffix "{*}Count{*}" for key strings, while the current format employs the suffix "{*}TableCount{*}." As a result, Recon is unable to interpret the data properly.
> A simple fix for this would be to either add a handler that gets triggered upon recon starting, or just change the prefix back to *"Count".*
