CPU USAGE DISPLAY (CPU Statistics)

From the "top" man page:

"There is a possible workaround if you define the CPULOOP=1 environment
variable. The top command will be run one extra hidden loop for CPU data
before standard output."

You could define this in the appropriate cfg file on each client.

 Mark,
        I failed to mention that in the man pages for TOP in CentOS 6.5,
the –d command line option is called the interval which I had read
somewhere is used to average statistics over. I hope that helps make it
more clear and understandable.

        Sorry for the delay mark. I took off a couple of days.

        By interval I mean the time span that is used for the calculations
in the cpu stats in the third line of TOP. The first display is calculated
across the time since boot. The second 'interval' is the time calculated
for those same cpu stats since the last iteration of the TOP display which
is...well... it looks like 1 or 2 seconds. Thus that is what I mean by
‘interval’. Interval is whatever is the measured period of time over which
any given TOP display’s cpu statistics are calculated. Xymon shows the
first display of TOP which looks like the first screen shot below. Then
from the same server virtually a few seconds later, I captured a second
display of TOP. Notice the cpu statistics are very different even though
the REAL condition of the server hadn’t changed at all. I would like to
change xymon to display that second iteration of the TOP command.

        Let me know if you would like more clarification. Thanks! J

Hello everyone,
          I am pretty new to the Linux world. Getting to the point
quickly; xymon apparently uses the top display for the CPU display. When I
see a CPU alert from xymon I’d like to see the current time interval’s CPU
stats (The third line of top display - %us, %sy, %ni, etc) rather than the
averages of those stats since the last reboot of the machine. This is an
old ‘complaint’ in bugzilla which was closed in 2007 as ‘not a bug’. I
couldn’t find any work-arounds or customizing tips out there to change the
display in xymon. What changes can a person make to see the current time
interval (any top display other than the first one) statistics for the cpu
display in xymon? What about changes in the monitored OS? Any suggestions
are appreciated! Thanks.

I think I know what you are asking for, but to be sure can you define what
you mean by "current time interval" ?


Thanks!
