Catching up on release notes, I think I see what you're after now... I'll be upgrading my instance this week... I'll let you know what I find 🙂

What are you looking for, specifically?
I've not upgraded my Harvest instaces to the latest verison, so I don't know if there is a new dashboard available, but I don't think the last one had any dashboards for SnapMirror operations / status. I've used the 'Network Port' and 'Network LIF' to get an idea of what the ICL ports are doing... but that's about it.
I've traditionally used OnCommand (ActiveIQ) Unified manager for my quick view into SnapMirorr operations and status.
