Allmost all of the switches of the switches show, these almost periodic white bands.
Its a routed network so no spanning-tree issues, and links/interfaces are also stable.
Could polling/sample interval have caused this effect.
Chances are yer pollin stopped working for a bit.
You want an alert looking for that stuff, and a couple alerts looking at solarwinds health so you can identify if it's the device's fault, your service's fault, or something else. There's a few posts on the forum here on each topic.
You're looking for lastuptimepollutc being in the past and the lastdatabasekeepalive (sp?) times.
Yeah my first though seeing bands like that would be a polling gap.
Do they all line up where all devices went white at the same time or are they staggered?
If everything stops polling at once I usually interpret that to be the polling engine or database having trouble. From here it looks like they are consistent at 3 hour intervals, so I'd definitely be looking to see if there was maybe a recurring job scheduled on the db server that might be interfering, or some similar kind of issue. Those look too frequent and consistent to be "random" stuff.
I also just noticed you have your default node statistics interval at 1 minute, that is something that can only work in pretty small environments. What is your polling engine showing for utilization on the All Settings > Polling Engines page?
