If you have devices being polled more than 7.5 minutes apart, this will cause missing data as RRD will not generate an average and will just insert a null value, leading to the white space.
We recommend not running Observium in a VM or on shared storage as it tends to cause these kinds of issues when the host/storage resources is being used by other applications.

I had the same problem with Observium and ~100 devices with observium running in a KVM instance, for me it turned out that disk iops wasn't enough, so the pollers didn't finish before the next round started. I just got a small SSD and put the Observium virtual machine on that and everything worked ok since then.
If your banding is of the same sort you should see that periodically you have too many pollers running at the same time.

Hi all,
I've been using observium a while ago and since the beginning the tool showed me the graphics like I show you in the attached picture.
There are several "white spaces" marked on the time period (X axis), where the tools is not showing information. I read the FAQs section and I found this advice:
"I'm getting a blank browser window on some pages, but not others", so I incremented the PHP memory parameter from 128M to 384M whithin the php.ini file but this did not work either so I come to you beggin your advice in order to resolve this problem. Besides I have 90 network equipments monitored with the observium application on a virtual server (6 GB of ram and 3 CPUs 3.0 Ghz).
thank you so much for any help
