I have been seeing that on the C7 DNS Server is missing.
However, C8 I see the DNS Server.
Both are configured the same on the networking and both should be getting it from DHCP. However, I would like to confirm that.
Make sure the Extended Network Data preference has a valid poll queue (and that the queue has a valid number of minutes/hours), Save Preferences, and then hit Refresh. Should populate at that point.
Great! I didn't see that seeing. That worked. Thank you.

@thebearmay I just upgraded from C-7 to C-8 Pro and my hub Information device started throwing errors:
java.lang.NumberFormatException: For input string: "8 Pro" on line 490 (method configure)
I put a Band-Aid on it by:
The Hub Information device page still shows C-8 Pro, but at least I got the errors to go away. Now my Node-Red / InfluxDB / Grafana setup is getting data from the device, so I can see the memory graph:
Looks like you missed an update, v3.0.36 should have the fix you need (it’s similar to your patch).

The first thing I did was check Hubitat Package Manager for updates, but now I see I wasn't on V3 at all. Updating now. Thanks!

@thebearmay - Anything to be concerned about w/the % of Busy? Do I have any settings messed up?
Settings:
The % of busy is misleading. Your hub has only been "busy" 1.9% of the time, of the tiny 1.9%, 63% was from this device. Guessing not a lot else is going on with that hub?

Yes, it's on my "quiet" C7 which has about 40 Zigbee devices, several Linptech mmWave sensors, and a couple integrations. I should have been clearer - I assumed not a big deal given the small overall busy level of the hub, but was a little surprised that the Hub Info device was by far the biggest user of that time.
1.2% of total is pretty much what I see on all 4 of my hubs.

So as long as you're here...any "Why the heck did you do that?!" thoughts about my settings? 
Does this only happen after a reboot? It looks like the hub information app is starting up after a reboot and might be requesting information from the hub before it’s ready. Also, it’s only a warning, not an error.
That was supremely helpful. Thanks.

Perhaps has something changed recently? I get Error 500 any time I try to Save Preferences or Save Device in the driver.
No log errors other than the usual warn on reboot after I updated to 2.3.8.124 today. I tried deleting the HubInfoTemplate.res file in case it was bad, but it was re-created, as expected.
Hub Info 3.0.36
C-8 with 2.3.8.124
Don’t know if this issue existed on prior firmware versions.
Everything seems to be working, though, except for the Error 500 issue.
Edit: same error after Hub Info update to 3.0.37.
