Have a page where to look how values differ for a given key #55
Description
Feature request: Create a page where to pass as parameter in the the name of an hiera key to analyse (for easy links wherever this key is shown) which shows what are the values for this key on all the nodes.
Ideally the list should be compressed to group nodes which have the same value and show information of the affected node (how many nodes have a given value) and possibly an option to expand them.
It would be nice, also, in the same page or another, to show where, for a given node, there's a duplicated and redundant entry which can be removed. For example where the same key with the same value is in common.yaml and in a node specific yaml, in this case the node specific entry is redundant and there should be a button to quickly remove it.
- point: Design in a way that fits cases where the number of nodes could be in the order of a few thousand.
