Seasoned system administrators know that routinely reading system logs is an important task, but reading endless lines from logs is both time-consuming and boring, especially if you are responsible for a large number of busy servers. In this article I will show you how to set up a system that gathers and archives system logs from many network hosts and emails only important or irregular system events to administrators.

CLI Magic: Viewing system information

01/09/2008  IIIIIII
Relevance: 3.44
GNU/Linux is bursting with information about the system on which it runs. The system's hardware and memory, its Internet link and current processes, the latest activity of each user -- all this information and more is available. And, despite such desktop tools as the KDE Control Center or GNOME's System Monitor, the easiest place to get all the system information available is still the command line. In many cases, you can view system information via specific commands. Some of these commands are written specifically to give information, while other commands that are mainly intended to alter the system in some way just happen to include parameters for viewing the current state of the system.

Review: Shuttle XPC SN27P2 barebones desktop system

12/13/2006  IIII
Relevance: 3.29
A few weeks ago, I decided to start looking for a new system. After a fair amount of searching, I settled on a Shuttle XPC SN27P2 barebones system that includes the case, motherboard, and power supply. Since it's hard to find information about supported hardware under Linux, I thought I'd share my experience with the XPC. It's a tiny system that can pack a hefty punch, and it's a good system for users who want to run Linux.

06/10/2008  IIIII
Relevance: 3.26
Computer users expect their systems to work well at all times, but unfortunately this isn't always the case. If your system becomes slow, there certainly is something you can do about it. This article will help you understand what's happening on the system, whether it's the computer in front of you or a system you're accessing remotely. Naturally, I presume you're running Linux, and the tools described here are Linux tools. If you're on some other weird system ( ;) ), your mileage may vary.

Who's Using Linux on the System i?

10/30/2006  IIIII
Relevance: 3.08
IBM first announced the availability of Linux on the iSeries in May 2001--more than five years ago. With great fanfare, Big Blue has consistently touted this Linux capability as a means for shops to realize cost savings and simplicity by capitalizing on the huge (outside the System i community) movement towards open source software and through server consolidation. All the appropriate heads nodded at the time, and certainly no one is arguing that the System i's ability to run Linux or other operating system partitions is in any way a bad thing.
