Lynis is an auditing and hardening tool for Unix derivatives like Linux/BSD/Solaris. It scans systems to detect software and security issues. Besides security-related information, it will also scan for general system information, installed packages, and possible configuration mistakes. The software is aimed at assisting automated auditing, software patch management, and vulnerability and malware scanning of Unix-based systems.
Epikscan is a cluster aware, diagnostic script that runs basic health checks and gathers detailed, addressable system information from an RHEL, Scientific Linux, Oracle/OVM2, or CentOS 4, 5, or 6 system. A single archive is created for each host, containing the scan data along with linking information that can be merged with scans from other nodes to produce a cluster oriented report. HTML, text, XML, and SQLite3 database reports can be optionally generated to support both manual and automated fault analysis. The scan and merge process attempts to heuristically identify possible problems with the node or cluster configuration and highlights them in red to speed up the review and resolution process.
Nagstamon is a Nagios status monitor with a UI that resides in the systray or as a floating statusbar on your desktop. It informs you in realtime about the status of your Nagios, Icinga, Opsview, Ninja, Check_MK/Multisite, Centreon, or Thruk-monitored network. It alerts you with sound and visual notification. Failed hosts and services are easy to connect with by SSH, RDP, and VNC. Custom actions can be run on certain events. It works best with GNOME, but also with KDE, Mac OS X, and Windows.
Ultimate Boot CD is a collection of Freeware and Free Software tools for PC diagnostics and maintenance. Included are tools for BIOS editing, CPU and memory testing, boot management, data recovery, peripheral and system inventory, and hard drive partitioning, cloning, wiping, diagnostics, and low-level editing. All tools boot and run from the CD.
check_openmanage is a plugin for Nagios that checks the hardware health of Dell servers running OpenManage Server Administrator (OMSA). The plugin can be used remotely with SNMP or locally with NRPE, check_by_ssh, or similar. It checks the health of the storage subsystem, power supplies, memory modules, temperature probes, etc., and gives an alert if any of the components are faulty or operate outside normal parameters.
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.
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.
