Strange Network Graph

[Rudolf]

Hello forum,

What might cause so "strange" graphs:

[Alexei]

Zabbix doesn't draw lines if timestamp difference between points is more than 4*refresh period.

[Azrael]

I'm having the same problem - but it only seems to occur when multiple people are viewing the graphs at the same time.

Hi Alexei,

what causes this? Could it be a time difference on the servers? Too much work in the queue? Too long query times?

thanks,
Timo
