The ability to search for a host amid 1000s is also useful. One of the problems is that I have tried to address use cases that scratch a particular itch for me (and I believe tons of other people). I am sure there are tons of other uses cases I am not seeing since I don't have things like multigrid etc. I would hope that someone who has such a setup could help. > I'd suggest that your json view structures look to not have considered > deployment in a multicluster, multigrid world. Multicluster works because the unique identifier is hostname. I suppose this could break if hostname is in multiple clusters. This can be addressed but I can't see the use case where you'd put same hostname in multiple clusters.
