  • 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.

  • Observium – Observium is an autodiscovering SNMP based network monitoring platform written in PHP which includes support for a wide range of network hardware and operating systems including Cisco, Windows, Linux, HP, Dell, FreeBSD, Juniper, Brocade, Netscaler, NetApp and many more. Observium has grown out of a lack of network monitoring platforms which are both simple to manage and pleasant to use. It is intended to provide a navigable interface to the health and performance of your network. Its design goals include collecting as much historical data about devices as possible, using as much auto-discovery as possible with little or no manual intervention, and having a very intuitive interface. Observium is not intended to replace an up/down alerting system like Icinga or Nagios, but rather to complement it with an easy to manage, intuitive representation of historical and current performance statistics, configuration visualisation and syslog capture.
  • nikratio / S3QL — Bitbucket – S3QL is a file system that stores all its data online using storage services like Google Storage, Amazon S3, or OpenStack. S3QL effectively provides a hard disk of dynamic, infinite capacity that can be accessed from any computer with internet access running Linux, FreeBSD or OS-X. S3QL is a standard conforming, full featured UNIX file system that is conceptually indistinguishable from any local file system. Furthermore, S3QL has additional features like compression, encryption, data de-duplication, immutable trees and snapshotting which make it especially suitable for online backup and archival. S3QL is designed to favor simplicity and elegance over performance and feature-creep. Care has been taken to make the source code as readable and serviceable as possible. Solid error detection and error handling have been included from the very first line, and S3QL comes with extensive automated test cases for all its components.
  • Secure encrypted backup using duplicity for Linux and Mac – I have been looking for a replacement alternative to Dropbox which I use on my Mac mainly for backups (I rarely use the sharing). The requirements were secure encrypted backup (where I control the keys) and “intelligence” so incremental backups could be performed i.e. not copying everything every time[…]
  • Duplicati – Duplicati is a free backup client that securely stores encrypted, incremental, compressed backups on cloud storage services and remote file servers. It works with Amazon S3, Windows Live SkyDrive, Google Drive (Google Docs), Rackspace Cloud Files or WebDAV, SSH, FTP (and many more).   Duplicati has built-in AES-256 encryption and backups can be signed using GNU Privacy Guard. A built-in scheduler makes sure that backups are always up-to-date. Last but not least, Duplicati provides various options and tweaks like filters, deletion rules, transfer and bandwidth options to run backups for specific purposes. Duplicati is licensed under LGPL and available for Windows and Linux (.NET 2.0+ or Mono required). The Duplicati project was inspired by duplicity. Duplicati and duplicity are similar but not compatible. Duplicati is available in English, Spanish, French, German, Danish, Portugese, Italian, and Chinese.
