This would suggest that you are on a multi-processor system and the process running is multi-threaded to take advantage of the hardware. You will only get up to 100% per processor, but they will be totted up for a multi-thread process.
Do you have 40 processors or more?
The other potential is for a process that is started during the time that top is taking it's sample. If it takes 0.1 seconds for top to collect everything and a process starts after 0.09 seconds but still gets collected, I have seen that skew the figures momentarily.
Perhaps from the command line, you could use vmstat 2 2 at the time and find the CPU counts there for the whole machine. You can also:-
... on older unix servers to get the busiest process at the bottom of the list and you can check if it is newly started. The sort would change to:-
I need to capture the following data on an hourly basis through cronjob scheduling:-
1. load averages
2. Total no. of processes.
3. CPU state
4. Memory
5. Top 3 process details.
All the above information is available through the command 'top'. But here we need to automate the same and... (4 Replies)
hi,
I want to extract and save the cpu(s) information from top command output, but individual cpu statistics separately on a multi-processor machine.
In command line, top will show this statistics when we press the switch "1".
any ideas?
thanks,

io::async::pid
IO::Async::PID(3pm) User Contributed Perl Documentation IO::Async::PID(3pm)NAME
"IO::Async::PID" - event callback on exit of a child process
SYNOPSIS
use IO::Async::PID;
use POSIX qw( WEXITSTATUS );
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $kid = $loop->fork(
code => sub {
print "Child sleeping..
";
sleep 10;
print "Child exiting
";
return 20;
},
);
print "Child process $kid started
";
my $pid = IO::Async::PID->new(
pid => $kid,
on_exit => sub {
my ( $self, $exitcode ) = @_;
printf "Child process %d exited with status %d
",
$self->pid, WEXITSTATUS($exitcode);
},
);
$loop->add( $pid );
$loop->run;
DESCRIPTION
This subclass of IO::Async::Notifier invokes its callback when a process exits.
For most use cases, a IO::Async::Process object provides more control of setting up the process, connecting filehandles to it, sending data
to and receiving data from it.
EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_exit $exitcode
Invoked when the watched process exits.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
pid => INT
The process ID to watch. Must be given before the object has been added to the containing "IO::Async::Loop" object.
on_exit => CODE
CODE reference for the "on_exit" event.
Once the "on_exit" continuation has been invoked, the "IO::Async::PID" object is removed from the containing "IO::Async::Loop" object.
METHODS
$process_id = $pid->pid
Returns the underlying process ID
$pid->kill( $signal )
Sends a signal to the process
