atop

[Don-44]

Hi,

 

I am posting here because developer/maintainer has told me he does not have time
to work on this anymore and I should look elsewhere. So I hope this is the
correct place.

 

I am using atop_1.21-1_i686.ipk and I have discovered a problem with it.  On a
system with multiple CPUs the CPU (not cpu) values are sum of the cpu values
when it should be the average.

 

CPU | sys      3% | user      0% | irq       0% | idle    196% | wait      0% |

cpu | sys      2% | user      0% | irq       0% | idle     98% | cpu000 w  0% |

cpu | sys      1% | user      0% | irq       0% | idle     99% | cpu001 w  0% |

 

For example idle for CPU shows as 196% when it should be 98%. This happens for
all of the CPU values.

Is this the correct forum for this or do I need to keep searching?

Well you've picked a mailing list for the NSLU2 which is a small _single_ CPU NAS device (although the distros are used on some other NAS's).

What system are you using this on?  Presumably you're using a SlugOS variant as you've installed an ipkg, but what stream have you obtained that from?

Does this happen on any other systems (i.e. alternative OS's on multi-core computers) with multiple CPUs that you've tried this on?  If so its a problem upstream (which by the sounds of it is unlikely to be fixed).

Hi,

It's running on a QNAP NAS (x86). The feed is
http://ipkg.nslu2-linux.org/feeds/optware/ts509/cross/stable/Packages.gz.

Ok, so does the failure for the percentages to tally up happen on any other systems?

Is your desktop computer multi-core?  If so do you observe the same behaviour you've described with atop on that as you do on your QNAP?

This would help identify whether the error is with atop in general or the specific build you are using.

Sorry my desktop is Windoze. The only devices I have that run Linux are three
NAS devices. Only one of them is dual core.

Hi,
I'm running atop v1.23 on a couple Ubuntu systems and both show CPU totals
over 100%.
I believe that is the intended behavior.

from the atop man page:

       CPU  CPU utilization.
            At  least  one  line  is shown for the total occupation of all
CPU’s
            together....

Maybe it's the intended behavior but is it the correct behavior?  If one line,
CPU, is intended to show the numbers for all cpus, in other words an overall
view of the system, how can a system be over 100% idle or busy or .? Maybe a new
line should be added that shows the average.
