    Comprehensive System Accounting and BSD Style Accounting


    Howdy! My company has currently decided to move one of our application servers from HP-UX to Red Hat Enterprise Linux 4 WS. The HP-UX comes with a different system and process accoutning package than RHEL4. RHEL4 by default comes with the GNU Accounting Utilities. Because of this, the old scripts we would use to collect process accounting information no longer work. These scripts would basically gather the login id, a particular process name, and the start and end times of that process. We would use this information to bill clients.

    I have tried installing the Comprehensive System Accounting package available from the oss SGI web site, however I cannot get this package working. I have only been able to get the oldest version installed because of multiple package dependencies on the newest version. However, after installation I haven't been able to get the package to run correctly. I keep getting errors stating in order to run I have to correct previous errors, however I cannot find any previous error messages.

    Does anyone know if I can use the GNU Accounting Utilities to get the above mentioned information, and if so how would I go about doing this. If not, has anyone gotten the CSA package to work on RHEL 4 and if so, how?

    Thank you for your help!

    Thumbs down

    Embedded developers are always trying to find novel ways of improving the performance of their products, either by improving the execution time of their code, lowering the RAM footprint needed by their applications, or both. A post on LKML asking about filesystems that support Application XIP sparked an interesting discussion on whether XIP is needed, including a message pointing to changes that will add XIP functionality to an ext2 filesystem mounted read-only. Most of the responses to the initial question said that XIP isn't really needed to improve performance, but the consensus was that RAMFS may be the best choice since RAMFS is a file-system implemented in pagecache and Linux runs code from the page-cache anyways. Implementations for XIP are also available for cramfs, however you lose the benefit of compression for the executables.Do some kernel level programming.
