Sar (Unix)
System Activity Report (sar) is a Unix System V-derived system monitor command used to report on various system loads, including CPU activity, memory/paging, interrupts, device load, network and swap space utilization. Sar uses /proc filesystem for gathering information. Platform support Sar was originally developed for Solaris operating system and it is available in Linux, Solaris, AIX, HP-UX, but it is not available for macOS or FreeBSD. Prior to 2013 there was a bsdsar tool, but it is now deprecated. Linux distributions, such as Debian, Red Hat Enterprise Linux, SuSe and Ubuntu provide sar utility through the sysstat package. Syntax sar flags -e time -f filename i sec -s time ; : filename Uses filename as the data source for sar. The default is the current daily data file /var/adm/sa/sadd. ; : time Selects data up to time. The default is 18:00. ; : sec Selects data at intervals as close as possible to sec seconds. Example ser@localhost sar # Displays curre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iostat
iostat (''input/output statistics'') is a computer system monitor tool used to collect and show operating system storage input and output statistics. It is often used to identify performance issues with storage devices, including local disks, or remote disks accessed over network file systems such as NFS. It can also be used to provide information about terminal (TTY) input and output, and also includes some basic CPU information. Syntax and availability iostat -x displays output where each line (row) gives numerical data for one device. The first column lists the device name, and subsequent columns show various statistics for that device. Columns include the average service time (''svc_t'', which includes not only the time a request is in the service queue, but also the seek time and transfer time), the average busy percentage (''%b'', essentially the proportion of time that the device is in use), and the percentage of time that the queue is not empty (''%w'', which means the ...

Job Scheduling
A job scheduler is a computer application for controlling unattended background program execution of jobs. This is commonly called batch scheduling, as execution of non-interactive jobs is often called batch processing, though traditional ''job'' and ''batch'' are distinguished and contrasted; see that page for details. Other synonyms include batch system, distributed resource management system (DRMS), distributed resource manager (DRM), and, commonly today, workload automation (WLA). The data structure of jobs to run is known as the job queue. Modern job schedulers typically provide a graphical user interface and a single point of control for definition and monitoring of background executions in a distributed network of computers. Increasingly, job schedulers are required to orchestrate the integration of real-time business activities with traditional background IT processing across different operating system platforms and business application environments. ''Job scheduling'' s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM AIX
AIX (Advanced Interactive eXecutive, pronounced , "ay-eye-ex") is a series of Proprietary software, proprietary Unix operating systems developed and sold by IBM for several of its computer platforms. Background Originally released for the IBM RT PC RISC workstation in 1986, AIX has supported a wide variety of hardware platforms, including the IBM RS/6000 series and later IBM Power microprocessors, Power and PowerPC-based systems, IBM System i, System/370 mainframes, IBM Personal System/2, PS/2 personal computers, and the Apple Network Server. It is currently supported on IBM Power Systems alongside IBM i and Linux. AIX is based on UNIX System V with 4.3BSD-compatible extensions. It is certified to the UNIX 03 and UNIX V7 marks of the Single UNIX Specification, beginning with AIX versions 5.3 and 7.2 TL5 respectively. Older versions were previously certified to the UNIX 95 and UNIX 98 marks. AIX was the first operating system to have a journaling file system, and IBM has c ...

Ksar (Unix Sar Grapher)
Ksar is a BSD-licensed Java-based application that creates graphs of all parameters from data collected by Unix sar utilities. Usually, Unix sar is part of Unix' Sysstat package, and runs sa1, sa2, and sadc through cron to created data files in /var/log/sa/saNN. Characteristics include: * Images can be zoomed by dragging the mouse on an image to pinpoint problems * Results can be exported to PDF or JPEG format Syntax and options Below is the list of CLI options supported by Ksar. Ksar's -help option will list all supported options of the applicable Ksar version. $ java -jar kSar.jar -help kSar version: 5.0.6 Usage: -version: show kSar version number -help: show this help - input : argument must be either ssh://user@host/command or cmd://command or file://path/to/file or just /path/to/file -graph : space separated list of graph to be output -showCPUstacked: will make the CPU used graph as stacked -showMEMstacked: will make the memory graph as stacked (Linux only) -cpuFixedAxi ...

Nmon
nmon (''Nigel's Monitor'') is a computer performance system monitor tool for the AIX and Linux operating systems. The nmon tool has two modes a) displays the performance stats on-screen in a condensed format or b) the same stats are saved to a comma-separated values (CSV) data file for later graphing and analysis to aid the understanding of computer resource use, tuning options and bottlenecks. nmon for Linux is open source and available under GNU General Public License while the nmon for AIX is a proprietary software integrated into AIX. Description nmon collects the following operating system statistics: * CPU and CPU threads Utilisation * CPU frequency for servers or virtual machines that can alter their clock rate * GPU stats including utilisation, MHz and temperatures * Physical and Virtual Memory use * Disk read & write and transfers plus service time and wait times * Disk Groups - decided by the user * Swap and Paging * Network read & write and transfers * Local File-syste ...

CIFS
Server Message Block (SMB) is a communication protocol originally developed in 1983 by Barry A. Feigenbaum at IBM and intended to provide shared access to files and printers across nodes on a network of systems running IBM's OS/2. It also provides an authenticated inter-process communication (IPC) mechanism. In 1987, Microsoft and 3Com implemented SMB in LAN Manager for OS/2, at which time SMB used the NetBIOS service atop the NetBIOS Frames protocol as its underlying transport. Later, Microsoft implemented SMB in Windows NT 3.1 and has been updating it ever since, adapting it to work with newer underlying transports: TCP/IP and NetBT. SMB implementation consists of two vaguely named Windows services: "Server" (ID: LanmanServer) and "Workstation" (ID: LanmanWorkstation). It uses NTLM or Kerberos protocols for user authentication. In 1996, Microsoft published a version of SMB 1.0 with minor modifications under the Common Internet File System (CIFS ) moniker. CIFS was compatible w ...

Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ser ...
