I'd like to see the boot date/time of the device displayed in the ZCC which is good to know in general for troubleshooting and also if patches were recently applied that required a reboot. This should display in the inventory data as well as on the device's Patches tab next to the "Last PS time".
True, it is captured in inventory and reported in ZRS (Inventory > Software and Hardware Information > Software Specific Attributes > Operating Systems > Boot Time) but we only scan once a week currently so it can be stale data. Since we have currently scheduled our CDF to be daily, we could create an ADF to capture the data using a custom script to populate a reg key so that the data is more current. Ideally, the agent device registration event could upload that bit of info so it is more real-time and that would be nice. FYI, I was also able to find it in the nc_operatingsystem.boottime field if you can run manual queries.
I currently get around this issue by running a PowerShell script that posts the Days Hours Minutes the system has been online and have Inventory post the results. Works for most clients on my Zone but requires a manual refresh of inv cdf which is part of my bundle process. It would be nice to see as part of the reported default.
