> I had c6403 fail to resolve hostname c6402, which causes the hostname resolution warning. That all showed fine as expected (see attached).
> But, it doesn't provide any more details. It told me c6403 had a hostname resolution failure but didn't tell me c6402 failed. If it had to resolve a lot of hosts, this might be hard to track down. I believe the API gives back the info (how many failed and which hosts they were), we can include that in the UI and report.
