Description
The ReplicaSet Summary dashboard shows ReplSet States and MongoDB Versions. It works fine when all nodes are available, but when a node is down:
The node disappears from ReplSet States when it goes past the selected metrics window
It disappears from the MongoDB Versions list. It should still be visible there (last version information available). For this point 2, for MongoS, a spin-off ticket has been created: .
Possible help for implementation here:
See the screenshots for more details
How to test

Check cluster summary dashboard → versions panel, version of the down node should be visible (currently Excluding MongoS versions from this story
How to document
