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. -

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. -

Optimizing AIX 7 Performance: Part 1, Disk I/O Overview and Long-Term Monitoring Tools (Sar, Nmon, and Topas) Martin Brown October 12, 2010 Ken Milberg
Optimizing AIX 7 performance: Part 1, Disk I/O overview and long-term monitoring tools (sar, nmon, and topas) Martin Brown October 12, 2010 Ken Milberg Learn more about configuring and monitoring AIX 7 based on the investigations of AIX 7 beta compared to the original articles based on AIX 5L. The article covers the support for direct I/O, concurrent I/O, asynchronous I/O, and best practices for each method of I/O implementation. This three-part series on the AIX® disk and I/O subsystem focuses on the challenges of optimizing disk I/O performance. While disk tuning is arguably less exciting than CPU or memory tuning, it is a crucial component in optimizing server performance. In fact, partly because disk I/O is your weakest subsystem link, you can do more to improve disk I/O performance than on any other subsystem. View more content in this series Introduction A critical component of disk I/O tuning involves implementing best practices prior to building your system. Because it is much more difficult to move things around when you are already up and running, it is extremely important that you do things right the first time when planning your disk and I/O subsystem environment. This includes the physical architecture, logical disk geometry, and logical volume and file system configuration. When a system administrator hears that there might be a disk contention issue, the first thing he or she turns to is iostat. iostat, the equivalent of using vmstat for your memory reports, is a quick and dirty way of getting an overview of what is currently happening on your I/O subsystem. -
