I have a QuestDB Enterprise cluster, and I would like to be able to know if I am working with a primary or a replica from the web console.

I can execute a query like select value from (show parameters) where property_path='replication.role'; to get back primary or replica, but what I would like is some way of adding visually to the web console the label directly, in the same way that at the bottom right it shows the QuestDB version I am using.

There is a trick that works both for QuestDB Open Source and for QuestDB Enterprise.

These two environment variables are picked by the web console:

export QDB_INSTANCE_NAME=WhatEverName
export QDB_INSTANCE_RGB=b

The second option needs to be lowercase r,g, or ,b and it will set the background for the text you enter for the first variable. This displays at the top left of your web console, as in this screenshot.
