Some devices not graphing like they used to

So the last few days graphing of my gateway has somehow stopped. Only shows a few spikes here and there. See image. And I will post a image of the last week as well just to compare normal graphing of the gateway like it used to be.

Both the gateway and the rpi running librenms has been rebooted just to be sure. So what is going on here?

I can’t tell what those graphs are supposed to be showing as you’ve cropped out and not included any details.

Yeah well, there is really nothing to hide. It’s a gateway. that all my local clients goes through to get online. And as you can see the graphs was a drawn with more details of the traffic for about 7 days ago. And now there is only a few spikes here and there, even if the real traffic is a lot more. (Had 4 10GB wget downloads of test files running randomly without it showing in the gateway graph)

What does the graph look like for the week before and even the month/year before that?

I’m really confused now, but going back in the history of the graphs really skewers the look of things in my opinion. And I guess everything is just fine, but I looks so “naked”, I somehow think there should be more details in the graphs.

It’s a difficult one, port polling is a stable piece of code and if it was broke generally we’d know about it.

This could be an issue with your device, maybe try restarting the net-snmp daemon on the client box to see.
