Free system information data collector software for linux

System Configuration Collector Server generates summaries of scc-data sent by clients. System Configuration Collector Server offers a Web interface that supports searching the snapshots and the logbooks of the systems. It also supports comparing (parts of) the snapshots of systems.
Enhancements:
- This release uses CSS directives to indicate different colors when comparing data from systems.
- It handles the case of an empty log.html when sort is implemented by busybox.
- stdout and stderr are recorded from client runs in the log file when started by scc-pull.
- A puppylinux package has been added.
- style.css has been updated to show variable data in scc snapshots.

Kwok Information Server project is a Web-based information management system for managing issues, contacts, and IT assets including hardware and software licenses. The Issue Management module provides users a way to report issues and search for the issues they need to work on.

The IT Asset Management module provides hardware tracking and software license tracking. The Contact Management module allows users to create and maintain contacts. The Administration Tool module allows administrators to manage system users and to modify the system configuration.

There is built-in support for access control, email notification, LDAP authentication, file uploads, and more.

User Account Information provides an ethernet users/customers traffic counter.
User Account Information is lightweight system for accounting for ethernet traffic on a per-user basis.
It includes a Web-based interface for allowing users to view their own network accounting information.
This product was designed and was tested in RedHat Linux 6.2 and in SlackWare Linux 7.0.
Main features:
- For each customer (who have IP adress in your local network area) are added two ipchains rule for counting input and output traffic.
- Each customer can look his own account information through WEB-interface.
- You ( as system administrator) can correct anything You want or anything you dont like in this program.
Enhancements:
- A date format error solely affecting output with DD/MM/YYYY action dates was corrected in the cgi-bin part.

Webcomics Collector is a GPLed python script for downloading webcomics. Webcomics Collector can start from the frontpage and work its way back through the archive of a webcomic, downloading the entire archive independently of dates or naming of strip-images.

There is order in which the strips should appear is recorded in a file which the webinterface and frontends can use. FYI: Alot of webcomics dont name their strip-images in a way that allows you to just fire up an imageviewer and start reading, so it is recommended that you use the webinterface.

The Boehm-Demers-Weiser conservative garbage collector can be used as a garbage collecting replacement for C malloc or C++ new.
Boehm-Demers-Weiser Conservative Garbage Collector allows you to allocate memory basically as you normally would, without explicitly deallocating memory that is no longer useful. The collector automatically recycles memory when it determines that it can no longer be otherwise accessed.
The collector is also used by a number of programming language implementations that either use C as intermediate code, want to facilitate easier interoperation with C libraries, or just prefer the simple collector interface.
Alternatively, the garbage collector may be used as a leak detector for C or C++ programs, though that is not its primary goal.
Typically several versions will be available. Usually you should first try to use gc_source/gc.tar.gz, which is normally an older, more stable version.
If that fails, try the latest explicitly numbered version in gc_source/. Later versions may contain additional features, platform support, or bug fixes, but are likely to be less well tested. Note that versions containing the letters alpha are even less well tested than others, especially on non-HP platforms.
A slightly older version of the garbage collector is now also included as part of the GNU compiler distribution.
The collector uses a mark-sweep algorithm. It provides incremental and generational collection under operating systems which provide the right kind of virtual memory support. (Currently this includes SunOS[45], IRIX, OSF/1, Linux, and Windows, with varying restrictions.)
It allows finalization code to be invoked when an object is collected. It can take advantage of type information to locate pointers if such information is provided, but it is usually used without such information. ee the README and gc.h files in the distribution for more details.
The garbage collector distribution includes a C string (cord) package that provides for fast concatenation and substring operations on long strings. A simple curses- and win32-based editor that represents the entire file as a cord is included as a sample application.
Performance of the nonincremental collector is typically competitive with malloc/free implementations. Both space and time overhead are likely to be only slightly higher for programs written for malloc/free (see Detlefs, Dosser and Zorns Memory Allocation Costs in Large C and C++ Programs.)
For programs allocating primarily very small objects, the collector may be faster; for programs allocating primarily large objects it will be slower. If the collector is used in a multithreaded environment and configured for thread-local allocation, it may in some cases significantly outperform malloc/free allocation in time.
We also expect that in many cases any additional overhead will be more than compensated for by decreased copying etc. if programs are written and tuned for garbage collection.
Enhancements:
- The C code now requires at least C89.
- The live data in the heap is now counted, helping to make the heap expansion heuristic more robust.
- Thread local allocation support was enhanced.
- Some obsolete platform support such as old-style Solaris threads was removed.
- Some new platform support was added.
- Various bugs were fixed.

DB based NetFLow Collector aims to collect Cisco NetFlow data and store it to a database.
DB based NetFlow Collector has a plugin interface, which makes it flexible for fitting in particular tasks.
Enhancements:
- First release. post your comments/bug reports.

XMLSysInfo is a system monitoring daemon that replies to network queries with XML-encoded system information and statistics. This data can then be analyzed, graphed or otherwise presented by a front-end. It is BSD-licensed and free for anyone to use for any purpose.
Or, because it sounds so much better:
XSI is an agile, vertical XML application for mission-critical enterprise environments that leverages collective synergy to drive "outside of the box" thinking and formulate key objectives into a win-win game plan with a quality-driven approach that focuses on empowering key players to drive-up their core competencies and increase expectations with an all-around initiative to drive up the bottom-line.
It is currently under heavy development and in its "alpha" stage. The XML output grammar may still change a bit, but all in all, "beta" is approaching fast.
