CPU LOAD

I have setup Hobbit in a Solaris environment,

which has systems with a different number of

CPU's.

 
In the past with Big Brother, I had to edit the cputtab

file and add the different loads for each system.

 
Is there a way that allows me to specify the CPU

load based on the number of CPU's on the system?

 
Thanks..James

Sorry, I should have phrased this better.

 
I have 200 systems with multiple cpu's ranging from

2, 4, 6, 8 or 24 cpu's. 

 
Instead of adding every system name in hobbit-clients.cfg

with a different LOAD variable. s there a way that

HOBBIT can use the number of CPU's automatically for the load?

 
Something like LOAD=Number of CPU's X LOAD_NUMBER

 
Thanks for the assistance.

James,
 
Not that I know of.  I thought that the Unix "load" number simply
reflects the run queue length for the system as a whole, which is pretty
much the same no matter how many CPU's there are.  Or are you willing to
tolerate larger numbers for systems with fewer CPUs?
 
Perhaps you can whip up a script to read your BB cputab and generate the
necessary hobbit-clients entries?

20 processes in the run queue is bad on a system with 1 cpu
20 processes in the run queue is no problem for a system with 64 cpu's

Perhaps.  I defer to the wisdom of the group.

Thanks Henrik,

I have my old bb-cputab entries which I can script
to convert. Can you recommend a conversion number
for the load.

On the old bb, I use to put 300 per cpu for warning
and 400 per cpu for alert.

So, a system with four cpu's would be:
1200 and 1600

So, how would this compare to the LOAD variable?

Any recommendations would be appreciated.

Thanks...James

Well, just add a dot before the last two digits :
300 -> 3.00
400 -> 4.00
1200 -> 12.00
1600 -> 16.00

it's that simple :). Note that recent versions of the BigBrother client
(since 1.9e I guess) can use this syntax too.
