The Assimilation Monitoring Project is a highly scalable discovery-driven monitoring system. It integrates continuous discovery of servers, services, service dependencies, switch connections, and lots of other things into the monitoring process. The discovery is "stealthy" and will never set off any network security alarms. Adding servers doesn't measurably increase monitoring load, and the system is expected to easily scale into the 100K server range. The discovery work is distributed among all the nanoprobes (agents), which run scripts that spit out JSON. The central system (CMA) stores these strings and runs optional plugins to create graph nodes.
DeTraS provides several tools to track development activities by registering applications that developers use on an X11 session. It also allows you to send collected data to a server and takes care about your privacy. The idea behind DeTraS is taken from Timeline, a shell script written by Nat Friedman.
FSter is a virtual filesystem implementation based on FUSE and exploiting Tracker's indexer to allow access to files according to the metadata with which they’re associated. Its behavior is highly customizable with XML configuration to describe in detail the desired hierarchy of files.
GoAccess is a real-time Web log analyzer and interactive viewer for almost every Web server. It runs in a terminal and provides fast and valuable HTTP statistics for system administrators that require log monitoring and visual reports on the fly. GoAccess can monitor unique visitors, browsers, spiders, OS, hosts and IP geolocation, keyphrases, referring sites, status codes, etc. It has support for IPv6 and it parses nearly any Web log format.
ntdisp, short for NtD In System Programming, is a system for programming LPC and STM32 (and possibly other) embedded devices. It provides three different frontends, a GObject-based library (for developers), a commandline utility (for computer geeks), and a GTK+3 frontend (for less geeky users).
wsh allows you to execute commands on multiple machines in parallel. It is secure and fast, and even outperforms ansible. It works by having an agent live on the machine. When you run wshc, it sshes and execs wshd and sends commands over the encrypted channel. wshd executes the commands and sends the results back.
