If it did, then what you are seeing makes sense.

Xymon looks for status changes.
If everything went down, including Xymon, then it would never have
received any messages, nor been able to perform any other tests, like
ping etc.

I am guessing that when power was restored, you brought up all your
other servers first, and then started Xymon. Or they all started up around the same time.

The root cause of your issue, or rather the lack of issue, is that
Xymon never recieved any reports of problems. Because it couldn't.

Yes, it's exactly what happened and no one is shocked about this behaviour ?

I would expect, at least, a white stripe in the "History" page of each status check. Nothing has been reported during 6h, this is never happens in a every day functioning. Type or paste your English text here and click on the "Check Text" button.

In our case the UPS would alert Xymon its on battery and has lost input power. Then it would start shutting down boxes after a few minutes causing box status reports to change colour and then it would shut down cleanly.

Everything would already be red before its turned back on again.

As part of a clean shutdown though maybe Xymon shouldn't leave stuff green for the duration its turned off. I've never really checked what it does at that point..

When the power came back, Xymon came back too. I've checked all
 monitored equipment, everything was green during the past 6h. I was
 expecting purple or white color because no data has been reported during
 the time. Is that a bug or a setting I could adjust ?
