[hobbit] RE: CPU Utilization Part 2 -- HELP!!!

James, I suspect that the CPU utilization numbers come from "vmstat"
output.  There should be a section in the client data labeled [vmstat]
and the numbers that are graphed are listed in the far right hand
columns.  I guess the [iostatcpu] section could be used as well -- that
adds the "wt" column to "us, sy, and id".
 
On one of my Solaris systems, I have something that looks like this:
 
[vmstat]
kthr      memory            page            disk          faults
cpu
r b w   swap  free  re  mf pi po fr de sr s0 s1 s3 --   in   sy   cs us
sy id
0 0 0 22683696 6595936 41 257 1 0 0  0  0  3  2  0  0  573 1703  631  1
2 97
0 0 0 22077552 5982992 38 240 0 0 0  0  0  3  3  0  0  608 3125  839  2
2 97
[iostatcpu]
     cpu
us sy wt id
  1  2  0 97
  2  2  0 97

It is possible that your vmstat output is not formatted the way that
Hobbit expects (extra columns?)  Your graph looks different -- usually
the CPU utilization graph for Solaris is a stacked area chart, not a
line graph.
 
Others may be able to chime in with more things to consider.  Good luck!

	The Operating System is Solaris.

	The graph definitions have not been changed.

	 

	What should I look for with the client data?
	I'm not familiar with rrd.

	 

	Although if I look at all the clients overall, I see

	the same thing, the averaging of CPU Utilization

	is a flat-line on everything, even during peak loads.

	 

	Thanks...James

	What OS, version, etc.  And did you look into your client data
file to see what is in there?  And has anyone monkeyed with the graph
definitions?

	 

	You have the smoking gun, but that's about all we have to work
on...

		I could not send all the graphs in the same email.

		This is the same system with the other two graphs,

		but this is a different monitoring tool another group

		uses. It shows CPU Utilization at 100% which is

		correct with a load of 120+. However, Hobbit, showed

		a flatline at 13%..

		 

		I'm seeing this across the board on all the systems,

		and the tool below is being used by the other group

		showing the discrepancies. Any suggestions?

		 

		 

		 

		Thanks....James

		I really need some help on the CPU Utilization graphs.

		They just don't look correct.

		 

		As an example, CPU Load on this box went to 120+,

		for an hour, but the CPU Utilization Graph for the same

		time period shows only 13% busy.
