You can think of graph.php as an API based on HTTP GET requests.

from and to can contain either a unix timestamp or a number of seconds relative to the current time.

This is how we use it internally, so the URL structure is pretty well defined and doesn't change.

Note that in general you need to be logged in to view graphs, so for this kind of thing I'd usually recommend either running a script to periodically GET the graphs (with authenticated CURL requests) and store them statically, or (less secure) to allow unauthenticated graph viewing from your office IP block.

Hi Joe,

If you remove the to= parameter, you can set from= to a negative number, i.e. number of seconds from now. To display a graph for the last 24 hours, set it to -86400.

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,

Thanks Tom, that is exactly the fix I was looking for. He just opens my web page (or just presses F5) and he has updated graphs.

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.
