Webcockpit is a Web application generator for reporting and monitoring applications. It generates complete JSP-based Web applications which contain charts and tables whose contents are retrieved using database queries. The charts and tables can be configured to link to each other, enabling master detail-like drill-down. You can provide your own HTML or JSP template files which are mixed with the generated JSP to provide a final Web application.
NagiosAppender is a pure Java implementation of a Log4j appender that allows the developer/administrator to send log records to Nagios via the NCSA server (using the push model). It provides a simple solution for Nagios administrators whose only alternative is to implement a polling function against against the output of a standard Log4j appender. The log4j configuration file provides for user-specific mappings between Log4j levels and Nagios levels. The configuration file also allows the user to select whether to set the Nagios 'service' and 'host' programmatically via Log4j MDC, or via the config file. Later releases support XOR encryption.
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.
SysScope is a graphing solution that facilitates the visual representation of RRDtool's Round Robin Databases (RRD). It retrieves the graph options from an Apache-style configuration file and, after making the necessary calls to rrdgraph, it generates static or dynamic HTML pages containing the graphs. The following backends are supported for the generation of the dynamic pages: CGI, FastCGI, mod_python, and WSGI.
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.
OpenArm is an implementation of the Open Group's Application Response Measurement (ARM) standard. It provides a complete implementation of the ARM 4.0 Java interfaces, as well as ARM agent functionality that allows you to record your transaction events as log4J logging events, JMS messages, SNMP traps, JMX notifications, or as records in a relational database.
