"Welcome to the sixth article in the long series on Kernel crash collection and analysis. We have started the series with LKCD, an older utility, followed by a very long review of Kdump, both of which are available as PDF guides, free for download. Next, we learned about new features and changes in the Kdump setup and functionality on openSUSE 11.2 and CentOS 5.4. Now, it's time to start processing the collected memory cores.

"Today, we will do just that. Learn how to use the crash utility to open the dumped memory cores, collected at the time of kernel crashes, and read the information contained therein. Please note that this article focuses mainly on being able to use and process the crash dumps. We will focus on the crash analysis more deeply in the next tutorial.

"Like the previous five installments, the article is mainly intended for power users and system administrators, but if you wish to enrich your Linux knowledge, you're more than welcome to use the tutorial. Some of the steps will require in-depth familiarity with the functionality of the Linux operating system, which will not be reviewed here."
