Ujorm is an easy-to-use ORM framework based on key-value objects. The framework was designed for rapid Java development with great performance and a small footprint. The key features are type safe queries, relation mapping by Java code, no entity states, and a memory overloading protection cache.
The goal of JavaMelody is to monitor Java or Java EE application servers in QA and production environments. It is a tool to measure and calculate statistics on the real operation of an application depending on the usage of the application by users. JavaMelody is easy to integrate in most applications. JavaMelody is mainly based on charts and statistics of requests, such as memory, CPU, HTTP, EJB, Spring, Guice, JSP, JSF, Struts, or SQL requests.
sec-wall is a feature-packed security proxy that supports SSL/TLS, WS-Security, HTTP Auth Basic/Digest, extensible authentication schemes based on custom HTTP headers and XPath expressions, powerful URL matching/rewriting, and an optional header enrichment. It's a security wall with which you can conveniently fence otherwise defenseless backend servers.
Panoptes is a scalable, extensible network and host monitoring tool. It includes a dynamic Web management interface based on the Dojo toolkit. It monitors SNMP, TCP port availability, ICMP, HTTP response and content, and SSL certificates internally. It supports monitoring anything else via shell scripts. It also includes a packet capture tool for discovery of hosts, port, and OS.
Embedded Profiler is low-overhead C++ profiler based on automatic instrumentation of functions done by the compiler (GCC, MinGW, or MSVC). Profiling can be done either automatically or manually. Automatic profiling generates a complete call tree and needs no modification of code. Manual profiling requires using the EProfiler API to specify the parts of code to be profiled. The resulting log can be opened in Performance Analyzer, a GUI application with several views designed for comfortable log analysis.
libnodelay is an LD_PRELOAD library for disabling Nagle's algorithm. Disabling Nagle's algorithm can result in a performance improvement for latency-sensitive applications that use TCP. Using the library may be easier than digging through a mess of code and confusing or obscure configuration options.
libLunchbox facilitates the development and deployment of multi-threaded applications. It provides OS Abstraction, using utility classes abstracting common operating system features (such as threads, locks, memory maps, shared library loading, and condition variables), high-performance primitives (including thread-safe utilities tuned for performance, such as atomic variables, spin locks, and lock-free containers), and utility classes (including helper primitives which are not in the standard library, such as logging, pools, and random number generation).
Torrus is an alternative software platform to MRTG, Cricket, and Cacti. In most cases it brings more flexibility and performance. It is able to poll more than 50,000 SNMP OIDs every 5 minutes from a single moderately equipped server, with simultaneous threshold monitoring of half of them. Torrus is designed to be a universal data series processing framework. Its scalable hierarchical design, application-independent core, and highly customizable architecture make it an attractive choice both for small installations and for big enterprise or carrier networks. Although most users deploy Torrus for SNMP monitoring, it might be useful for data series of any nature. Tobi Oetiker's RRDtool is used for data storage.
gprog is a basic GUI pipe meter that shows the percentage complete as data moves through a Unix pipe. It is very fast because it uses a dual process design with a cache oblivious algorithm for self-tuning. Also, the presentation is largely decoupled from the transfer, so that the GUI won't slow down the transfer.
