Hi Scott, Is your goal to monitor the metadata upgrade? It can be checked on the web UI.
Before finalization, you can see a message on the top banner on the NN frontpage such as: "Upgrade for version -40 is in progress. Status = 94% has been completed. Upgrade is not finalized." After the upgrade procedure completes, its "Upgrade for version -40 has been completed. Upgrade is not finalized." At which point you can check for operational stability and issue a finalize to make the upgrade permanent. Does this help? Is there anything else you'd like to see?
