If your Xymon server was down how could it recognise that it had not received any data?
If it received data within 5 minutes of it restarting then I would fully expect it to show green for the intervening period. I don't think Xymon can recognise that it was itself down and therefore show white/purple in the history. The timer that causes these statuses would have been reset by the reboot which would mean that as long as it then receives data from the clients within the new refreshed timer period it would stay green.
The only way I can think of that would allow you to see when the power outage occurred on Xymon would be to have your Xymon server attached to a UPS that would keep it alive for at least 10 minutes.

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

When the power came back, Xymon came back too. I've checked all

expecting purple or white color because no data has been reported
during
the time. Is that a bug or a setting I could adjust ?
