In this CentOS 5.5 tutorial we will be installing Smokeping and SmokeTrace on a CentOS 5.5 i386 server. The assumption is that you have a basic to medium understanding of Apache but if you follow this tutorial you should be able to complete the task successfully.
A bit on the software that we’ll be using:
Smokeping
SmokePing keeps track of your network latency:
* Best of breed latency visualisation.
* Interactive graph explorer.
* Wide range of latency measurment plugins.
* Master/Slave System for distributed measurement.
* Highly configurable alerting system.
* Live Latency Charts with the most ‘interesting’ graphs.
* Free and OpenSource Software written in Perl written by Tobi Oetiker, the creator of MRTG and RRDtool

It’s a great day for CentOS and its community because, according to Web Technology Surveys, in July 2010, “For the first time, CentOS is now leading the Linux distribution statistics on web servers with almost 30% of all Linux servers.”

Originally developed by NYTimes, XSLCache extension for PHP is finally in PECL repository and ready for it’s first PECL-release.
“The XSL Cache extension is a modification of PHP’s standard XSL extension that caches the parsed XSL stylesheet representation between sessions for 2.5x boost in performance for sites that repeatedly apply the same transform. Although there is still some further work that could be done on the extension, this code is already proving beneficial in production use for a few applications on the New York Times’ website.”
Installation, from now on, should be as simple as pecl install xslcache
I have modified the linux installing guide, Installing and upgrading to PHP 5.2.9 on CentOS and Red Hat Linux 5.3 x86_64 to reflect this change.
