Add more poller_wrapper threads and a single device won't hold things up.

Turned out to be a router that wanted to take 600s to poll J. Disabled and we’re graphing again. Is there any way to set a polling timeout to ensure that one device doesn’t cause a problem like this?

If you're seeing holes in local host, it's almost certainly a problem with poller duration. You can see how long this takes in the poller information page (in the 'globe' menu, or /pollerlog/). 

If your poller wrapper is taking too long, that might cause the issue. You can see how long each device takes to poll on that page too.

It's not that easy to cause the problem you're seeing without having a system which is too slow (you'd be able to tell pretty easily, i think), or running too few poller wrapper threads. For your setup, run maybe 8 threads.

What is the content of /etc/cron.d/observium

Thanks,

There is, but I’m seeing similar holes in my graphs of the host (localhost) that observium is sitting on.

Hi,

 

Is there a firewall directly in front of your Observium server?

Hello all,

 

We’re seeing holes on our graphs (example attached). This appears to be affecting all graphs in our installation on all devices. I know our connection is good (affecting LAN and WAN devices), but looking for any other ideas for correcting this? We have also tried increasing the number of poller processes. Only around 1000 ports on this install, 8 GB of RAM and 4 vCPU.

 

Thanks,

Billy
