Checkservice is a Perl script that monitors services on remote hosts. It uses plugins to provide a more thorough check than just a socket check, and can be configured to check multiple services on multiple hosts using two different methods (simple and extended). It is able to write logs and when running in the background enables warnings. It features a beep-, mail-, and SMS-warning system.
DansGuardian is a Web content filtering proxy that uses Squid to do all the fetching. It filters using multiple methods including, but not limited to, phrase matching, file extension matching, MIME type matching, PICS filtering, and URL/domain blocking. It has the ability to switch off filtering by certain criteria including username, domain name, source IP, etc. The configurable logging produces a log in an easy to read format. It has the option to only log text-based pages, thus significantly reducing redundant information (such as every image on a page).
Expresso Framework is an open standards-based J2EE architectural framework that allows the developer to concentrate on application logic. It is a library of extensible Java Server application framework components for creating database-driven Web applications based on open standards. Expresso integrates with Apache Jakarta Struts, which emphasizes presentation and application configuration, and bringing a powerful tag library to Expresso. Expresso adds capabilities for security, robust object-relational mapping, background job handling and scheduling, self-tests, logging integration, automated table manipulation, database connection pooling, email connectivity, event notification, error handling, caching, internationalization, XML automation, testing, registration objects, configuration management, workflow, automatic database maintenance, and a JSP tag library.
The Jasmin software distribution includes an implementation of the Script MIB according to RFC 2592 with a Java runtime engine, a selection of demonstration scripts, a Java package called "scriptmib" supporting the development of manager applications for the Script MIB, Smurf, a graphical user interface to the Script MIB, and JAX, a Java package for building AgentX sub-agents.
Lrp Network Monitor is an applet/application that displays information about network devices on a Linux router. This information can be displayed either in plain text, or in graphical format (either bar-charts, line-charts, or a histogram). It also displays the status (online/offline) of ISDN-devices, and can trigger actions like dial or hangup.
Mars is a simple, extensible, services-oriented network status monitor written in Java. It monitors a network by simulating client connections to Internet services and reporting when those services are not responding as expected. It is quick and easy to install and configure, which distinguishes it from more complex network monitoring tools. Mars monitors HTTP, HTTPS, SMTP, IMAP, POP3, FTP, SSH, and JDBC, and notifies via SMTP and XMPP "out of the box". Support for new protocols, notifications, and reporting mechanisms is easy to add via Java or XML.
mod_atrack adds advanced user tracking functionality to the Apache Web server. It was based on mod_usertrack and introduces many new configuration features primarily designed to reduce the annoyance of sending multiple cookies to a single user and allow more intelligent analysis of collected data.
mod_backhand is a load balancing module for Apache. It provides per-request HTTP redirection within a heterogeneous Apache server cluster. Each request is processed and run through a set of "candidacy functions" to determine which server is best suited to respond. The request is then proxied to that server. Facilities are in place to allow you to write your own dynamically loadable decision making algorithms. Everything about the request and the current availability of resources can be used in the decision-making process.
