Add a monitoring that always shows the current primary
When there's an election and the primary changes, it's hard to get a good view on how does the primary functions in a macro fashion.
Please add a monitoring column (or an equivalent solution) that can show the monitoring information for the primary at the time, so I could look at the past month or so, and see how does the primary performed, even if it was a different server every time.
This will make it much easier to understand various actions we take like changing indexes, improving queries, upgrading the database version, upgrading the driver, etc.
Plus 1, it's so obvious. For now, it is not easy at all to have the big picture understanding of primary cluster behaviour when we look to a bigger timeframe.
