Synapse is an ESB engine and XML router built completely on open standards. It is a mediation framework for XML messages and Web services that allows messages flowing through, into, or out of an organization to be mediated, including aspects such as logging, service lookup, performance mediation, versioning, failover, monitoring, fault management, and tracing.
Apmiser is a daemon that monitors the CPU usage patterns of your laptop and automatically switches between power-saving mode (in which the CPU is underclocked) and normal mode, depending on whether it thinks you will need the extra CPU speed. This lets you leave your laptop in it's power-saving state without having to suffer from poor performance when you need to perform a CPU-intensive task. Apmiser currently only supports IBM Thinkpads via tpctl, but support can be easily added for any laptop that supports switching power-saving modes programmatically.
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.
Aradial RADIUS Server is a high performance RADIUS server with Tier 1 levels of reliability and scalability. It supports the latest RFCs, vendor specific attributes, and NAS templates, and has a multitude of pre-configured settings that support most access servers on the market today. It is based on a plugin architecture, which allows customization of the authentication and accounting logic outside of the core product. It is integrated with top billing solutions for ISP, WISP, Wifi, Hotspots, and VoIP.
Aranha is an application that uses an XML-RPC layer to retrieve information from one or more servers. The type of information gathered is implemented via plugins, and can be displayed or archived in several different ways. The data is gathered in Round Robin Databases (integrated with rrdtool) and can be accessed using a XUL interface available from the system. Plugins are very easy to write.
The Argus Open Project is focused on developing network activity audit strategies that can do real work for the network architect, administrator and network user. Argus is a fixed-model Real Time Flow Monitor designed to track and report on the status and performance of all network transactions seen in a data network traffic stream. It provides a common data format for reporting flow metrics such as connectivity, capacity, demand, loss, delay, and jitter on a per transaction basis.
