Hi,

[13:37] <      h01ger> | TheSnide: looking at
https://jenkins.debian.net/munin/debian.net/jenkins.debian.net/cpu.html again
i think there's clearly a problem: the upper "line" should be flat at 1500.
but it's very visibly *not* flat at all, there are many many small bumps.
there is some miscalculation...
[13:48] <     helmut> | h01ger: this cpu problem has existed for a loooong
time. I never found it important enough to track it down though.
[13:48] <      h01ger> | helmut: so you see it on real hw too?
[13:48] < helmut> I do
[13:49] <   TheSnide> | h01ger: IIRC it's due to the fact that the
read("/proc") and the write("rrd") isn't done at the same time
[13:50] <   TheSnide> | h01ger: the plugin should emit the real epoch of the
read. But that is something i need to confirm first. (I only looked at it
hastily)
[13:50] <      h01ger> | TheSnide: want a bug?
[13:50] <   TheSnide> | h01ger: that'd be awesome


cheers,
	Holger
