GoAccess is an open source real-time web log analyzer and interactive viewer that runs in a terminal in *nix systems. It provides fast and valuable HTTP statistics for system administrators that require a visual server report on the fly.
The U.S., U.K. and Canadian governments characterize hackers as a criminal menace, warn of the threats they allegedly pose to critical infrastructure, and aggressively prosecute them, but they are also secretly exploiting their information and expertise, according to top secret documents.[...]
GCHQ created a program called LOVELY HORSE to monitor and index public discussion by hackers on Twitter and other social media.
There is always a set of standard metrics that are universally monitored (Disk Usage, Memory Usage, Load, Pings, etc). Beyond that, there are a lot of lessons that we’ve learned from operating our production systems that have helped shape the breadth of monitoring that we perform at bitly.
Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. It leverages widely used technologies such as XML for data representation, XDR for compact, portable data transport, and RRDtool for data storage and visualization. It uses carefully engineered data structures and algorithms to achieve very low per-node overheads and high concurrency. The implementation is robust, has been ported to an extensive set of operating systems and processor architectures, and is currently in use on thousands of clusters around the world. It has been used to link clusters across university campuses and around the world and can scale to handle clusters with 2000 nodes.

This is a follow-up post on my previous post "Four Linux server moniting tools" which ended up on the frontpage of Hacker News for a pretty long time, and got a lot of great activity from a lot of people in the Hacker News community, and even people who has been developing on the mentioned tools.

La sécurité du protocole BGP suscite régulièrement de l'intérêt, en général suite à des attaques spectaculaires comme celle de Pakistan Telecom contre YouTube. En l'absence de mécanisme de signature cryptographique des annonces BGP (mécanisme très difficile à concevoir puisque les routeurs BGP, les préfixes IP et les AS ne forment pas un arbre mais un graphe très touffu), la seule protection contre les détournements est la vigilance. Il existe plusieurs moyens automatiques d'être prévenus d'un changement d'annonces BGP et j'en teste ici quatre.
France’s homeland security minister Manuel Valls has said he sees web monitoring as a priority in the fight to find terrorists.
