Also, realize that if you are in a virtual server, you are NOT guaranteed any "MHz" value, per se. You are given timeshare slices against a CPU that relate to the approximate value of one of your CPUs, which may or may not be a real CPU, if they are doing hyperthreading.
Hello all. I was on my pc last night when I noticed that my hard drive light was on and when I typed in "uptime" I recieved some crazy load averages. load average: 3.30, 3.07, 2.95. Anyway I type in "top" to see what processes are being the resource hogs and im surprised as hell to see that one... (2 Replies)
Hi all
I would like to check my production machine and find out which application is using up the resources of the Unix machine, is there a way to display individual applications that are running and the percentage of resources they are taking up? (2 Replies)
I am running a C program on a SCO box. There are multiple users on using the system resources. My problem is when using fprintfs in the program. I am writing to a log every thing I read in from a file after doing some formatting. I write out to the log with the fprintfs in groupings like 10... (3 Replies)
Hi,
is it possible to check smb-connections of my server? I want to see, which files are opened from which station (ip).

Hi Community,
I'm looking for a linux based utility for monitoring following system resources
1. Memory
2. CPU Usage

chcpu
CHCPU(8) System Administration CHCPU(8)NAME
chcpu - configure CPUs
SYNOPSIS
chcpu -c|-d|-e|-g cpu-list
chcpu -p mode
chcpu -r|-h|-V
DESCRIPTION
chcpu can modify the state of CPUs. It can enable or disable CPUs, scan for new CPUs, change the CPU dispatching mode of the underlying
hypervisor, and request CPUs from the hypervisor (configure) or return CPUs to the hypervisor (deconfigure).
Some options have a cpu-list argument. Use this argument to specify a comma-separated list of CPUs. The list can contain individual CPU
addresses or ranges of addresses. For example, 0,5,7,9-11 makes the command applicable to the CPUs with the addresses 0, 5, 7, 9, 10, and
11.
OPTIONS -c, --configure cpu-list
Configure the specified CPUs. Configuring a CPU means that the hypervisor takes a CPU from the CPU pool and assigns it to the vir-
tual hardware on which your kernel runs.
-d, --disable cpu-list
Disable the specified CPUs. Disabling a CPU means that the kernel sets it offline.
-e, --enable cpu-list
Enable the specified CPUs. Enabling a CPU means that the kernel sets it online. A CPU must be configured, see -c, before it can be
enabled.
-g, --deconfigure cpu-list
Deconfigure the specified CPUs. Deconfiguring a CPU means that the hypervisor removes the CPU from the virtual hardware on which
the Linux instance runs and returns it to the CPU pool. A CPU must be offline, see -d, before it can be deconfigured.
-p, --dispatch mode
Set the CPU dispatching mode (polarization). This option has an effect only if your hardware architecture and hypervisor support
CPU polarization. Available modes are:
horizontal The workload is spread across all available CPUs.
vertical The workload is concentrated on few CPUs.
-r, --rescan
Trigger a rescan of CPUs. After a rescan, the Linux kernel recognizes the new CPUs. Use this option on systems that do not auto-
matically detect newly attached CPUs.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
RETURN CODES
chcpu has the following return codes:
0 success
1 failure
64 partial success
