Monitorix
Monitorix is a computer network monitoring tool that periodically collects system data and uses the web interface to show the information as graphs. Monitorix allows monitoring of overall system performance, and can help detect bottlenecks, failures, unusually long response times and other anomalies. One part of the tool is a collector, called ''monitorix.'' This Perl daemon is started automatically like any other system service. The second program of Monitorix is a CGI script (''monitorix.cgi).'' Since version 3.0 Monitorix has its own HTTP server included, what makes installing an own web server unnecessary. Monitorix is free software licensed under the terms of the GNU General Public License version 2 (GPLv2) as published by the Free Software Foundation. It uses the RRDtool (written by Tobi Oetiker) and is written in Perl.

RRDtool
RRDtool (''round-robin database tool'') aims to handle time series data such as network bandwidth, temperatures or CPU load. The data is stored in a circular buffer based database, thus the system storage footprint remains constant over time. It also includes tools to extract round-robin data in a graphical format, for which it was originally intended. Bindings exist for several programming languages, e.g. Perl, Python, Ruby, Tcl, PHP and Lua. There is an independent full Java implementation called rrd4j. General data storage RRDtool assumes time-variable data in intervals of a certain length. This interval, usually named step, is specified upon creation of an RRD file and cannot be changed afterwards. Because data may not always be available at just the right time, RRDtool will automatically interpolate any submitted data to fit its internal time-steps. The value for a specific step, that has been interpolated, is named a primary data point (PDP). Multiple PDPs may be consoli ...

Free Software Foundation
The Free Software Foundation (FSF) is a 501(c)#501(c)(3), 501(c)(3) non-profit organization founded by Richard Stallman on October 4, 1985, to support the free software movement, with the organization's preference for software being distributed under copyleft ("share alike") terms, such as with its own GNU General Public License. The FSF was incorporated in Boston, Massachusetts, United States, US, where it is also based. From its founding until the mid-1990s, FSF's funds were mostly used to employ software developers to write free software for the GNU Project. Since the mid-1990s, the FSF's employees and volunteers have mostly worked on legal and structural issues for the free software movement and the free software community. Consistent with its goals, the FSF aims to use only free software on its own computers. History The Free Software Foundation was founded in 1985 as a Nonprofit corporation, non-profit corporation supporting free software development. It continued existi ...

Internet Protocol Based Network Software
The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a '' network of networks'' that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1970s to enable resource sharing. The ...

Munin (network Monitoring Application)
Munin is a free and open-source computer system monitoring, network monitoring and infrastructure monitoring software application. Munin is written in Perl and uses RRDtool to create graphs, which are accessible over a web interface. Its emphasis is on plug and play capabilities. About 500 monitoring plugins are currently available. It is intended to make it easy to determine "what's different today" when a performance problem happens and to provide visibility into capacity and utilization of resources. History Munin was started by Jimmy Olsen late 2003, based on RRDtool by Tobi Oetiker. Development has slowed since 2005, but Munin is a stable tool and is still maintained. “Its name is derived from Norse mythology. One of the two ravens who report the news of the world to the god Odin is called Munin, and the other is named Hugin. Munin is 'memory', and Hugin is 'thought'.” Architecture Plugins Plugins are the specialized programs that are called by Munin nodes to gat ...

Collectd
collectd is a Unix daemon that collects, transfers and stores performance data of computers and network equipment. The acquired data is meant to help system administrators maintain an overview over available resources to detect existing or looming bottlenecks. The first version of the daemon was written in 2005 by Florian Forster and has been further developed as free open-source project. Other developers have written improvements and extensions to the software that have been incorporated into the project. Most files of the source code are licensed under the terms of the GNU General Public License, version 2 (GPLv2), the remaining files are licensed under other open source licenses. Operation ''collectd'' uses a modular design: The daemon itself only implements infrastructure for filtering and relaying data as well as auxiliary functions and requires very few resources, it even runs on OpenWrt-powered embedded devices. Data acquisition and storage is handled by plug-ins in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tobi Oetiker
ToBI (; an abbreviation of tones and break indices) is a set of conventions for transcribing and annotating the prosody of speech. The term "ToBI" is sometimes used to refer to the conventions used for describing American English specifically, which was the first ToBI system, developed by Mary Beckman and Janet Pierrehumbert, among others. Other ToBI systems have been defined for a number of languages; for example, J-ToBI refers to the ToBI conventions for Tokyo Japanese, and an adaptation of ToBI to describe Dutch intonation was developed by Carlos Gussenhoven, and called ToDI. Another variation of ToBI, called IViE (Intonational Variation in English), was established in 1998 to enable comparison between several dialects of British English. Overview A full ToBI transcription consists of six parts: (a) an audio recording, (b) an electronic print-out or paper record of the F0 (fundamental pitch), (c) a tones tier, with an analysis of the tonal events in terms of H and L, (d) a words ...

Free Software
Free software or libre software is computer software distributed under terms that allow users to run the software for any purpose as well as to study, change, and distribute it and any adapted versions. Free software is a matter of liberty, not price; all users are legally free to do what they want with their copies of a free software (including profiting from them) regardless of how much is paid to obtain the program.Selling Free Software (gnu.org) Computer programs are deemed "free" if they give end-users (not just the developer) ultimate control over the software and, subsequently, over their devices. The right to study and modify a computer program entails that |
Logo Monitorix
A logo (abbreviation of logotype; ) is a graphic mark, emblem, or symbol used to aid and promote public identification and recognition. It may be of an abstract or figurative design or include the text of the name it represents as in a wordmark. In the days of hot metal typesetting, a logotype was one word cast as a single piece of type (e.g. "The" in ATF Garamond), as opposed to a ligature, which is two or more letters joined, but not forming a word. By extension, the term was also used for a uniquely set and arranged typeface or colophon. At the level of mass communication and in common usage, a company's logo is today often synonymous with its trademark or brand.Wheeler, Alina. ''Designing Brand Identity'' © 2006 John Wiley & Sons, Inc. (page 4) Etymology Douglas Harper's Online Etymology Dictionary states that the term 'logo' used in 1937 "probably a shortening of logogram". History Numerous inventions and techniques have contributed to the contemporary logo, includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Monitoring
Network monitoring is the use of a system that constantly monitors a computer network for slow or failing components and that notifies the network administrator (via email, SMS or other alarms) in case of outages or other trouble. Network monitoring is part of network management. Details While an intrusion detection system monitors a network threats from the outside, a network monitoring system monitors the network for problems caused by overloaded or crashed servers, network connections or other devices. For example, to determine the status of a web server, monitoring software may periodically send an HTTP request to fetch a page. For email servers, a test message might be sent through SMTP and retrieved by IMAP or POP3. Commonly measured metrics are response time, availability and uptime, although both consistency and reliability metrics are starting to gain popularity. The widespread addition of WAN optimization devices is having an adverse effect on most network monitoring too ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
