Zoom is a low-overhead graphical and command line profiler for Linux. Profiles are system-wide, precise down to the instruction level, and capture complete backtraces of C/C++/ObjC/Fortran/Assembly code. This lets you see exactly where time was spent, what code was running (user or kernel), and how that code was called. Drill down into a specific symbol, and Zoom shows source and assembly annotated with general and processor-specific tuning advice. It saves profiles as a single, self-contained session file that can be emailed or attached to bug reports. This lets you share what you find with colleagues or archive it for later review. Zoom also supports remote network profiling and scripting, making it ideal for embedded or server systems and automated workflows.
The ERPXE project simplifies the process of installing and customizing a multi-boot PXE server. Over 100 different plugins are available for download, including Windows, WinPE, Hiren’s Boot CD, Acronis True Image, Symantec Ghost, FOG, Ubuntu, Debian, Fedora, CentOS, openSUSE, Gentoo, RIP Linux, Slackware, Backtrack, PartedMagic, and many more.
ProcMeter3 is a program for monitoring the system status and other information and displaying it in a series of graphs or as text. Most of the information comes from the /proc filesystem (cpu usage, load average , processes information, memory usage, network traffic, interrupts etc.). Other information is available for other sources (date, time, email status, log file length, disk status etc.). The program is modular and highly configurable.
check_oracle_health is a plugin for the Shinken (Nagios) monitoring software that allows you to monitor various metrics of an Oracle database. It includes connection time, SGA data buffer hit ratio, SGA library cache hit ratio, SGA dictionary cache hit ratio, SGA shared pool free, PGA in memory sort ratio, tablespace usage, tablespace fragmentation, tablespace I/O balance, invalid objects, and many more.
check_logfiles is a plugin for Nagios which checks logfiles for defined patterns. It is capable of detecting logfile rotation. If you tell it how the rotated archives look, it will also examine these files. Unlike check_logfiles, traditional logfile plugins were not aware of the gap which could occur, so under some circumstances they ignored what had happened between their checks. A configuration file is used to specify where to search, what to search, and what to do if a matching line is found.
MyConnection Server is broadband testing software which measures connections for bandwidth speeds and connection quality for time critical applications such as VoIP, Video conferencing, and IPTV. It helps organizations assess networks for deployment of new/additional services and identify and resolve last mile customer connectivity problems with little need for the customer to assist in the resolution process. A network route testing component details the path of the connections and where packet loss and latency occur, including discovery of multiple routes to a destination. Remote Test Agents enable technical staff to customize and interactively manage the bandwidth testing process and perform extended quality testing over hours or days to address and resolve intermittent problems as required. Satellite Servers establish additional connection testing points at the application edge to accurately test actual application network paths.
The libexplain project provides a library that may be used to explain Unix and Linux system call errors. This will make your application's error messages much more informative to your users. The library is not quite a drop-in replacement for strerror, but it comes close: each system call has a dedicated libexplain function.
check_hpasm is a plugin for Nagios which checks the hardware health of Hewlett-Packard Proliant servers. To accomplish this, you must have installed the hpasm package. The plugin checks the health of processors, power supplies, memory modules, fans, CPU- and board-temperatures, and alerts you if one of these components is faulty or operates outside its normal parameters.
