Yeah, I didn’t speak clearly when I said live. Seeing graphs that update every five minutes would work just fine.

I think he was referring to the "link to graph" feature producing links with fixed unixtime timestamps in them.
I actually added the "realtime" graph feature to Observium precisely so I could have a dashboard open all the time with realtime graphs of transit/peering links. Remarkably useful during maintenance slots to see traffic moving around between links and to know very quickly if something didn't work right.
Polling a couple of OIDs at intervals measured in seconds isn't really going to be noticed by the device, not even by something 2 decades old.
You definitely don't want to "for real" poll even a modern device this quickly, though. Especially chassis-based or "stacked" devices will often behave very badly, since they communicate between individual OS instances to collect statistics, and this is often not cached very well.
But err, I don't think this is what he meant. :)

Be careful with this. Doing a “live” query of a platform can potentially spike the CPU of that target platform, and that can have potentially undesirable results for your traffic passing through that platform. This is one of the reasons why you generally want to be polling your devices every five minutes, not every five seconds.

Subject: [Observium] Create a shortcut to a live graph?
Hey all, is there a way to create a shortcut to a live graph in Observium? I’ve used the “Link to Graph” button but that just creates a static picture of what’s going on. I’d like to create a web page with graphs for my manager but those graphs need to display live data.
Thanks,
