aircrack-ng is a set of tools for auditing wireless networks. It's an enhanced/reborn version of aircrack. It consists of airodump (an 802.11 packet capture program), aireplay (an 802.11 packet injection program), aircrack (static WEP and WPA-PSK cracking), airdecap (decrypts WEP/WPA capture files), and some tools to handle capture files (merge, convert, etc.).
AppDynamics an application performance management solution for mission-critical Java applications. It can organize user requests and business transactions, monitor business transaction health, identify and diagnose slow requests, identify and diagnose errors, and drill down. It is built from the ground up for highly distributed service-oriented environments. It has fast root cause diagnostics at the method/class level, but creates no more than 2% overhead, even in high-volume production deployments. It can not only manage applications, but dynamically scale them in cloud and virtual environments.
Bandwidth Monitor NG is a small console-based live network and disk I/O bandwidth monitor for Linux, BSD, Solaris, Mac OS X, and others. It supports /proc/net/dev, netstat, getifaddr, sysctl, kstat, /proc/diskstats, /proc/partitions, IOKit, devstat, and libstatgrab. An unlimited number of interfaces and disks are supported. Interfaces and disks are added or removed dynamically from the list. You can white or blacklist interfaces and disks. The output includes KB/s, Kb/s, packets, errors, average, max, and total sum, and can be viewed via curses, a plain console, CSV, or HTML. Configuration can be done through a config file or the command line.
BixData is a cluster management tool that includes monitoring and system administration features. It monitors services (HTTP, ping, POP3, SMTP), performance, and processes. It has a management console for VMWare and Xen that supports multiple virtual machine hosts and guests. It can create critical notifications and send email alerts for any system event (HTTP, ping, CPU, memory, SMART diagnostics, VM stats). A graphical desktop supports real-time dynamic graphs. The runtime agents and server components are lightweight and easy to set up and run.
