Open Source Systems Administration Software

Daphne is a system tray application for process killing, controlling and debugging. It's development started back in 2005. It was first thought to kill a set of windows process at once. With the time it became a GPL task manager replacement for Windows. You can kill a process by dragging the mouse over the windows, by right-clicking the process in the main process list, or by typing its name with the "Kill all by name" command. You can set a any window to be always on top, to be transparent, to be enable, et cetera. Although Daphne was born just to kill windows process. You can think of Daphne as a task manager replacement. The main window displays a list of currently running process with detailed information about: CPU usage, Process ID, Process name, Full path (and arguments), Priority, Class (Process / Service), Current memory usage, Peek memory usage, Current swap usage, Peek swap usage and Number of threads.

MakeLogic Tail is an advanced "tail -f" command with GUI. It needs JRE 5.0, hence it is 'Tail for Windows', Linux or 'Tail for Mac'. It shows the last few lines of a growing log file in real time. Provides many more easy to use features. Try it!

Enables a user to view & alter all aspects of comunications with a web site via a proxy. Primarily used for security based penetration testing of web sites, it can also be used for debugging during development. Seen as part of a hacker toolkit.

It is a Process Monitoring Toolkit with the ability of Extend. E.g. You can use it to monitor a specified process. And set a triger like (over 50MB mem use) then do something like (report to DB).

Bugkilla is a set of java tools for the functional test of J2EE Web Applications. Specification and execution of tests will be automated for web front end and business logic layer. One goal is to integrate with existing frameworks and tools.

Glassbox is an automated troubleshooting and monitoring agent for Java apps that diagnoses common problems with one-click. Drop in a .war file from http://www.glassbox.com and find out what's wrong with your existing web apps, without any code chang

JCola is a file tailing application written in Java Swing. This multithreaded application can tail an unlimited amount of logfiles concurrently and simulates "tail -f" with much more functionality.

JRemoteRun allow execute snippets of java code in running JVM.

KerX (Kernel eXplorer) provides a simple way for reading the very low-level data structures of the OS (GDT, IDT, TSSs, Page-Tables, Page-Directories, etc...)

LimpidLog is a revolutionary logging for Java and J2EE. No hard-coded log statements required. Classes are dynamically registered at runtime. See http://www.acelet.com/limpidlog/ and related http://www.acelet.com/super/LimpidDebugger/

StackTraceSealer is a JConsole plugin with its own Java Agent Library that can be used to seal stack frames on a thread stack trace to detect whether these frames have changed or they have remained the same all the time to aid in finding an infinite loop on a production system when all you have is a long seemingly constant stack trace in the thread dump.

The beSee-2-x architecture brings JVM wide instrumentation for AOP systems, independant from bytecode kit (BCEL, Javassist). A plugin is provided to instrument BEA WebLogic (v7) for tracing purpose (servlet->EJB->CMP->DB), with full JMX capabilities.

Process io tracing through syscalls with syslog logging. Similar to strace, but specialized.

logview4net is a log viewer/log monitor for data created by various sources. It can listen to UDP, tail a file, tail a SQL table, monitor the eventlog and watch RSS and Atom feeds. It requires the Microsoft .NET Framework 2.0
