Hello,
I had one of my user saying : "Why does this interface appears in unknow while other are being displayed as ok on this particular widget?"
and I couldn't answer it. To illustrate I took two screenshots of the same widget behaving in different ways:
Here's the "correct display" with an historic of the interface status:

And here I took the same widget from the solarwinds demo (to show that I'm not the only one having this issue) :

where you can clearly see that the historic is missing or appears in "unknown"
Does someone knows why this is happening? is this a bug?
