Membrane SOAP Router is a modular SOAP intermediary written in Java. It is fully configurable due to Spring style configuration. You can audit SOAP traffic, route messages through DMZ, and gather performance statistics. The small memory consumption of less than 20 Megabytes makes it possible to run an instance of Membrane SOAP Monitor on any computer that provides or consumes Web services.
jmxsh is a fully scriptable command-line JMX client based on Tcl. It is simply a Tcl interpreter powered by Java/Tcl (with command-line history and editing provided by JLine) that has special command-line options for connecting to JMX servers and special Tcl commands for interacting with JMX servers. jmxsh is capable of simultaneously connecting to multiple JMX servers. There's also a "browse mode" for exploring the remote JMX namespace without knowing beforehand the names of MBeans or their properties. jmxsh and all its dependencies are distributed in a self-contained executable jar file for ease of use.
JSend NSCA is a Java API and command line tool for sending Nagios Passive Checks to the Nagios NSCA add-on. By using the JSend NSCA core API, you can easily integrate your Java applications into a Nagios monitored environment, thereby notifying Nagios of problems and issues during the running of your application. The JSend NSCA CLI command line tool wraps the API and allows you to send passive checks from the command line.
The WebReboot Plugin for Nagios is a suite of commands that can be used within Nagios to monitor a server and take corrective action if necessary via the WebReboot line of products. For example, the plugin can be used to alert you if a host is powered down, versus simply not responding to network requests. Likewise, it can be used to reboot a server if a host fails to respond to ping, or to shut down a server when a critical temperature threshold is exceeded. The commands can be mixed-and-matched with all existing Nagios commands, maximizing total network coverage.
Keywatch is a free, OSGi-based monitoring system that provides the adaptability of a modern monitoring system without being complex or hard to configure. It support agents written in any language, and comes pre-packed with a Perl agent and a set of check scripts. Keywatch also supports Nagios check scripts.
