Free cpu utilization software for linux

cpulimit is a simple program that attempts to limit the cpu usage of a process (expressed in percentage, not in cpu time). This is useful to control batch jobs, when you dont want they eat too much cpu.

cpulimit project does not act on the nice value or other scheduling priority stuff, but on the real cpu usage. Also, it is able to adapt itself to the overall system load, dynamically and quickly.

wmcputhrottle is a dockapp that controls CPU throttle based on acpi /proc filesystem.

Use it to save your laptop battery

Developed and tested only in a DELL INSPIRON 1100 runnind Fedora Core 2

Spumoni enables any program which can be queried via local commands to be health-checked via SNMP. This allows admins to use enterprise-level monitoring programs such as OpenNMS, Tivoli, OpenView, MRTG and RRDTool for even non-SNMP-enabled applications.
Spumoni acheives this efficiently using a native SNMP engine coupled with a stats collection daemon. Everything is highly configurable using modular XML files. Because of this modularity, the Spumoni project also contains a repository of configuration files to make monitoring various programs easier. A complete list of config files is available in the distribution package.
Main features:
- 100% Java means it can run on almost any platform.
- Licensed under the GPL. Special licensing also available.
- Low run-time utilization (only slightly more than your stats collection programs).
- Tested on Linux and Windows 2000.
- Uses a built-in SNMP daemon, so Net-SNMP is no longer needed.
- Includes an example MRTG front-end and a collection of monitoring config files to get you started.
Enhancements:
- Native SNMP TRAP and GET (agent) capability, thanks to JoeSNMP and Bob Sniders prototype code. This means that Net-SNMP, cfget and cfcat are no longer needed, so Spumoni runs just fine on Windows. Should make it more compatable on other platforms too.
- Added init.d-style startup script
- Added Windows batch file to run Spumoni
- Lots of code style standardization (thanks Checkstyle!)
- Tightened the XML DTDs
- Added CHANGELOG (this file)
- Added HTMLized source code to docs
- Added JUnit and Checkstyle Ant tasks
- Added JUnit and Checkstyle output to docs
- Greatly improved JavaDoc
- Improved build and versioning process
- Improved documentation & web site links

UMLMON is a complete run time environment for User Mode Linux. There is a separate monitor daemon for every VM.
UMLMON project creates the run time environment and starts the VM by executing the UML kernel. The daemon also determines the arguments that are passed to the UML kernel, and includes special support to set up arguments for memory size, virtual disks, virtual network interfaces, and console channels in a convenient way.
UMLMON also includes routines to do certain administration tasks like the creation of disks.
The team UMLMON + UML can be applied in the following areas:
- Server consolidation: Improve the utilization of server hardware, and ease the operation of servers.
- Virtual security zones: Instead of building demilitarized zones (DMZ) with real hardware, it is a cost-effective alternative to set up purely virtual DMZs on a single host.
- Virtual hosting: A cheap version of server hosting is virtual hosting; instead of leasing real computers to customers, virtual machines are used.
- Laboratory nets: By using virtual machines it is possible to build cheap laboratory nets, e.g. to test software in real network environments.
- Training environments: One can use virtual machines for Linux trainings where participants can get true administrators priviledges without any risks.
Enhancements:
- This release no longer call the problematic glibc function getgrouplist, which is often broken (symptom: segmentation fault immediately after starting umlmon).

Sys::CPU is a Perl extension for getting CPU information. Currently only number of CPUs supported.

SYNOPSIS

use Sys::CPU;

$number_of_cpus = Sys::CPU::cpu_count();
printf("I have %d CPUsn",$number_of_cpus);
print " Speed : ",Sys::CPU::cpu_clock(),"n";
print " Type : ",Sys::CPU::cpu_type(),"n";

In responce to a post on perlmonks.org, a module for counting the number of CPUs on a system. Support has now also been added for type of CPU and clock speed. While much of the code is from UNIX::Processors, win32 support has been added (but not tested).

Aero AIO: cpu/mem plugin mod is a mod of the cpu/memory plugin for aero aio. The hardware information is gathered via backends. You can easily write a python backend for your hardware.
Look at the files cpumemv2_backend.py, cpumemv2_default.py and cpumemv2_i8k.py to learn how to write backends.
Main features:
- default backend that supports CPU temeratures via /proc/acpi/thermal_zone and hard disk temperatures via hddtemp. You can start hddtemp by (as root)
- hddtemp -d /dev/hda
- Replace hda with the hard disk you want monitored.
- ibmacpi backend (for IBM laptops). Thanks to Frank Fiene. Supports CPU, GPU, hdd, fan and pci data, via the ibm acpi kernel module. Boy those IBM laptops have a lot of sensors!
- i8k backend (for Dell laptops). Supports cpu temp and fan speeds via the i8k kernel module.
- The backends are cascaded. The code automatically looks through all backends for support of each feature. the final feature set is the union of all backends
- If an update temporarily fails (this tends to happen with hddtemp), it is indicated on the theme by the : in front of the sensor name becoming an _

Ticket-IT is a tool for the creation, management, and accompaniment of tickets.
Ticket-IT is a tool directed towards companies that need a better integration and distribution of informantion about service to customers, support, development of products, callcenter, etc, among its several departments.
Ticket-IT has resource of easy utilization, concentration display and distribution of information, making possible its total adaptation to most distintc institutes and applications, being a perfect tool to HelpDesk, CallCenter and online support.
Main features:
Control and management of access
- User registration;
- Group registration;
- Access permission and actions based in group;
- Schedule of events;
- Users profile, top-configured;
Integration among sectors/departments
- Control of context categories, making possible the organization and cataloging of calls (tickets) being made or already made;
- Assign of users group per categories;
- Forwarding ticket to outer users that will be able to display calls and post comments;
- Partial or total ticket forwarding, making possible to manage information and function of the contributors of your company;
Information distribution
- Alerts via e-mail about create, opening, proceeding, close and re-opening or comments of tickets to those involved in categories;
- Main display of personal tickets, or collaborating, getting fast access to tickets, making service easier;
- Exchanging information based in a simple fulfilling of information, which due to Ticket-IT utomation, distribute it to those involved in the process;
- Protocol forwarding to outer agent access (customers, reps, etc) without the necessity of user and password;;
Enhancements:
- This release implements a Web installer and an option for personalization of the feedback message.
- The item "User of Companies" has already been implemented, along with its existing resources.
- A mask was applied (ticket comments and feedback) for guest users, so they will see the groups name instead of the users name in comments.
- Some minor bugs have been fixed.
- The gettext internationalization schema has been finished.
- The English (US) translation is done.
- There are some visual improvements.
