jniThreadCPUUsage is a Java library to get the amount of user and system CPU time used per thread. This is done via JNI, which calls getrusage() on the system. getrusage() is only available on Linux 2.6.26 or later and Solaris. One useful application of this is measuring the amount of CPU time used for a servlet request. getrusage() CPU time reporting is better than using the real time clock because it measures actual CPU time used and disregards times when the thread is idle or waiting (such as when it is waiting for network I/O).
BitNami Spree Stack greatly simplifies the deployment of Spree and its required dependencies. It can be deployed using a native installer, as a virtual machine, in the cloud, or as a module over an already installed infrastructure stack. Spree is a very powerful and flexible e-commerce platform written for the Ruby on Rails framework.
System Watchdog is a program that is designed to monitor a collection of Linux systems. It is configured to collect data on each monitored system at 5-minute intervals and build historical graphs using RRDTool. By default, it will gather statistics on CPU, memory, disk, and network usage. It also will attempt to monitor temperature and power settings. System Watchdog uses the paramiko module to ssh to all monitored systems. To access monitored systems, threads are implemented to access each remote host. After all threads have completed, watchdog will build a summary landing page to display the current status of each host, with links to a hardware inventory and resource graphs of each host.
jRapidRPC is a Java RPC library that allows you to create client-server applications that talk in objects. It is small, fast, and extensible. Its smallness helps you learn how to use the library quickly. jRapidRPC is fast due to its compact size and lack of complexity. Also, it uses the ProtoStuff serializer by default. jRapidRPC's extensibility allows you to can write a new client-server or a new serializer.
