White holes in xymon graphs 🔗 link

Hi,

can anyone explain those (white) blackouts in the attached xymon graph? I see no messages
neither in the client nor in the server logs.Those blackouts happen at different times:The duration is ~ 10 minutes = 2 intervalls?

Any hints?

This is the same thing I have been getting except my holes are only for one 5 minute interval and then repeats exactly 1 hour later, 2 hours later and sometimes 3 hours later. No messages, and other trending do not show any issue.

 
Are you running the 4.3.0 beta 2 version?

I've seen random holes caused by data being sent to the server twice
(happends if you interconnect multiple hobbit servers), but these
leave messages in rrd-status.log like "illegal update, minimum update
delay is 1 second".

Is the data really sent every 5 minutes? It could be delayed by some
(other) cronjob, and then get associated to the wrong time slot.

Hi,

i have those too and I'm running 4.2.0 on Debian built from source.
And the holes in trends match more or less exactly the time the server
was offline and/or rebooted.
Maybe this gives you a point where you can start your investigations.

Cheers

I too have seen these white holes and have not figured out a pattern.  I was getting errors in my rrd-status log about the time used to updates items, but for some reason that message stopped 15 days ago.  I am running 4.3.0-0.beta2
