Description
somewhat like #2. Grafana shows information for each PD even though it only has it for the PD leader. Then if the leader changes the chart for the new leader won't have history from the old.
It seems like a lot of our monitoring does not handle a PD leader change well.

Research direction
Start by reviewing the Grafana chart behavior described here and comparing it with issue #2. Trace how PD leader changes affect the displayed information and determine what monitoring behavior should preserve history across a change. Done means the chart retains the old leader's history and the monitoring behavior is verified across a PD leader change.
