Title: High CPU usage every 10 secounds.
Post by: robert.haugen@gmail.com on July 29, 2025, 03:37:32 PM
Hi.

Hawing two OPNsense installations. The CPU´s peek every 10 seconds. It was on 25.1 and the same on 25.7.

How high is "high"? The graph looks like "4", which doesn't seem high to me. I couldn't get a periodic blip on mine, and "Reporting: Health" -> "System, processor" doesn't seem to store with sufficient granularity for anything to show up (flat line). Think of a 10 second process - a pinger (monitor), perhaps?

cpu load stats from top (also a widget) is all that really matters.

Seeing a graph that says cpu is doing something, is not all that interesting.

Ah, but top isn't so good for looking for patterns or historical data, so I start with the graphs. But your point is good.

(I didn't even notice that the CPU widget always shows a grid height of four, since my CPU almost never gets that high.)

What do the grid line numbers mean? A nice "uniform" bell curve in that widget, that alone seems odd because there's nothing the CPU is doing that looks like that. It usually just ramps up almost instantaneously, and then dwindles down at a fast pace, so I would expect to see more of a sawtooth pattern.

I don't know, CPU widget doesn't see all that useful to me.

That whole "Lobby" is more for impressing "decision makers" and about "competitiveness" with comparators ;-)

Spinned up an OPNsense test instance. Same issue there.
