Only a guess, but given that it grows over time it could be that you have some kind of list or array-like entity that is growing without reasonable bound, and it is simply taking more CPU cycles to process the growing amount of data. It could be worthwhile to see if memory usage is also growing over time.

On one of my Solaris 10 box, CPU usage shows 100% using "sar", "vmstat". However, it has 4 CPUs and prstat and glance are not showing enough processes to justify high CPU utilization.

Hi all,
I'm using python and psutil a library to get system informations like cpu usage (percent) for a given process.
My question is if I have the value in % of the cpu usage how I could get the cpu usage in cycle number I mean not in percent?
Thanks a lot

statistics::basic::_twovectorbase
Statistics::Basic::_TwoVectorBase(3pm) User Contributed Perl Documentation Statistics::Basic::_TwoVectorBase(3pm)
NAME
Statistics::Basic::_TwoVectorBase - base class objects like Correlation
METHODS
query()
Query the value of the object. It will return the undefined value until there's something to calculate.
insert()
Insert two new new values into the vectors. This function must be given precisely two arguments and probably shouldn't be undefined
values in most cases.
# insert a 4 in one vector and a 3 in the other
$object_instance->insert( 4, 3 );
append() ginsert()
The growing insert inserts new elements, growing the max size of the vector to accommodate the new elements (if necessary). This
function must be given precisely two arguments and probably shouldn't be undefined values in most cases.
# append a 4 in one vector and a 3 in the other
$object_instance->ginsert( 4, 3 );
query_size()
The current size of the vectors -- regardless of their max size (as set by "set_size()"). This function returns a list, i.e.:
my @s = $obj->query_size; # two values
my $s = $obj->query_size; # the right hand value of the list
set_size()
Set the maximum size for the underlying Statistics::Basic::Vector objects. This function requires two arguments.
set_vector()
Set the vector objects used to calculate the object's value. This function takes two arguments -- which can either be arrayrefs or
Statistics::Basic::Vector objects. They must have the same number of elements.
my $v1 = vector
my $v2 = $v1->copy;
$example_correlation->set_vector($v1, $v2);
OVERLOADS
This class provides overloads. If evaluated as a string, it will attempt to print a pretty value for the object (or "n/a", see "query()"
above). the resulting string can be tuned, in terms of precision, see ipres for further information.
If evaluated as a number, it will try to return the raw result of "query()", possibly turning the resulting "undef" (if applicable) into a
0 in the process -- note that Perl does this 0-izing, not the overload.
The "eq" and "==" operators are also overloaded, trying to do the right thing. Also see toler for further information.
