These are my links for 18 mar 2014 through 21 mar 2014:

• tune apache peformance using mpm prefork module – There could be many reasons why your website performance is poor, one of them can possibly be that Apache is not coping with the load. Below you’ll find ready to consume configuration to make Apache performance better using the Apache MPM prefork module.
• check-httpd-limits – Check Apache Httpd MPM Config Limits – Google Project Hosting – check_httpd_limits.pl compares the size of running Apache httpd processes, the configured prefork / worker / event MPM limits, and the server's available memory. The script exits with a warning (or error message) if the configured limits exceed the server's available memory. The script does not use any 3rd-party perl modules, unless the –save/days/max command-line options are used, in which case you will need to have the DBD::SQLite module installed. It should work on any UNIX server that provides /proc/meminfo, /proc/*/exe, /proc/*/stat, and /proc/*/statm files. You will probably have to run the script as root for it to read the /proc/*/exe symbolic links.
• Apache 2.2: Multiple authentication providers « Electricmonk.nl weblog – Since Apache 2.2 multiple authentication providers are now supported. This is nice, since now you can have an LDAP authentication provider with an htpasswd fallback authentication mechanism.
• lozzd/Nagdash – What is Nagdash? Nagdash is the long awaited replacement of Naglite2. Written in PHP, it uses the Nagios-api, PHP and a sprinkling of jQuery and Bootstrap to provide a full screen, clean Nagios experience which is suitable either for a Dashboard/NOC screen, or simply a simple view to replace the Nagios UI.
• Naemon Monitoring Suite – Naemon is the new monitoring suite that aims to be faster and more stable, while giving you a clearer view of the state of your network.
