[BUG] Offline devices don't show data

[mjalindahl]

I'm a new subscriber, but I had an issue today with one of my servers where I believed it ran out of swap memory, crashed, and died.

When I got the alert that the Cloudflare tunnel was down, I knew what had happened. Or, at least, I suspected it. So, I run to my newfangled NetData dashboard, and lo and behold - it's blank.

Because the server is offline, the historical data is just blank. That is astronomically insane. So, I thought, "oh, maybe it's just the realtime view." Nope, changed the view to 1 hour, 1 week, 1 month, didn't matter.

What this means, is, if a machine fully dies - due to memory/disk/etc. issues, I'll never be able to troubleshoot it. Luckily, my machine was able to be started back up again. Historical data would be VERY key in troubleshooting a dead server. In my case, swap went to 100% and crashed the box. But I wouldn't have been able to see that until the box came back up.

Please, for the love of God, if a machine is offline, please still show historical data.
