Try these built-in commands and a few add-on tools. Most Linux distributions are equipped with tons of monitoring. These tools provide metrics which can be used to get information about system activities. You can use these tools to find the possible causes of a performance problem. The commands discussed below are some of the most basic commands when it comes to system analysis and debugging server issues such as: 1. Finding out bottlenecks. 2. Disk (storage) bottlenecks. 3. CPU and memory bottlenecks. 4. Network bottlenecks. #1: top - Process Activity Command The top program provides a dynamic real-time view of a running system i.e. actual process activity. By default, it displays the most CPU-intensive tasks running on the server and updates the list every five seconds. Fig.01: Linux top command Commonly Used Hot Keys The top command provides several useful hot keys: Hot Usage Key t Displays summary information off and on. m Displays memory information off and on. Sorts the display by top consumers of various system resources. Useful for quick identification of performance- A hungry tasks on a system. f Enters an interactive configuration screen for top. Helpful for setting up top for a specific task. o Enables you to interactively select the ordering within top. r Issues renice command.

  • Chapter 3. Booting Operating Systems
    Chapter 3. Booting Operating Systems Abstract: Chapter 3 provides a complete coverage on operating systems booting. It explains the booting principle and the booting sequence of various kinds of bootable devices. These include booting from floppy disk, hard disk, CDROM and USB drives. Instead of writing a customized booter to boot up only MTX, it shows how to develop booter programs to boot up real operating systems, such as Linux, from a variety of bootable devices. In particular, it shows how to boot up generic Linux bzImage kernels with initial ramdisk support. It is shown that the hard disk and CDROM booters developed in this book are comparable to GRUB and isolinux in performance. In addition, it demonstrates the booter programs by sample systems. 3.1. Booting Booting, which is short for bootstrap, refers to the process of loading an operating system image into computer memory and starting up the operating system. As such, it is the first step to run an operating system. Despite its importance and widespread interests among computer users, the subject of booting is rarely discussed in operating system books. Information on booting are usually scattered and, in most cases, incomplete. A systematic treatment of the booting process has been lacking. The purpose of this chapter is to try to fill this void. In this chapter, we shall discuss the booting principle and show how to write booter programs to boot up real operating systems. As one might expect, the booting process is highly machine dependent. To be more specific, we shall only consider the booting process of Intel x86 based PCs.

  • How to Maintain Happy SAS® Users
    NESUG 2007 Administration & Support How to Maintain Happy SAS ® Users Margaret Crevar, SAS Institute Inc., Cary, NC ABSTRACT Today’s SAS ® environment has high numbers of concurrent SAS processes and ever-growing data volumes. It is imperative to proactively manage system resources and performance to keep your SAS community productive and happy. We have found that ensuring your SAS applications have the proper computer resources is the best way to make sure your SAS users remain happy. INTRODUCTION There is one common thread when working with the IT administration staff at a SAS customer’s location with regard to what they can do to maintain happy SAS users, and that is to ensure that underlying hardware is properly configured to support the SAS applications. This is not a trivial task since different SAS applications need to have the hardware configured differently and depending on where you are with your understanding of how SAS will be used will help you evaluate options for the hardware, operating, and infrastructure (mid-tier) configuration. This is easier for existing SAS customers and more difficult with new SAS customers or new SAS applications at an existing SAS customer site. In this paper we will: • discuss briefly how SAS works, especially from an IO perspective • give some guidance on how to initially configure hardware for SAS usage • give some guidance on how to monitor the hardware to avoid running out of a computer resource • discuss if you should run all your SAS components under a single operating system or split them across multiple operating system This paper pulls together information that has been presented in recent SAS Global Forum and SUGI papers.
