Monitoring Network Services in Internet
Styblík, Zdeněk ; Vasilenko, Alexandr (advisor) ; Rostislav, Rostislav (referee)
Diploma thesis deals with design and implementation of solution for monitoring servers and services over the Internet in combination with application for monitoring, Nagios. Common solutions are presented and evaluated first and serve as basis for design and implementation of a custom solution. Some of existing solutions were used, eg. HTTP protocol, others were developed, eg. scripts to automatically change Nagios configuration. Alternative solution for monitoring servers and services is the result of this diploma thesis.

ISP Network Management
Svoboda, Filip ; Pavláček, Martin (referee) ; Ondrák, Viktor (advisor)
The subject of this thesis is management of computer network managed by internet service provider in the village Boleradice. Based on the analysis of current management practices weakness in monitoring was revealed. In order to address this issue a server was purchased, on which was installed Nagios, an advanced monitoring tool. The benefit of this project is increased efficiency and improved management of the network and ability to quickly respond to outages of network devices.

Monitoring the operation of local internet networks
Papež, Nikola ; Bartl, Milan (referee) ; Verner, Lukáš (advisor)
This thesis deals with issues of traffic monitoring of local internet networks. Attention is paid to describing main functions and methods of network monitoring, consequently standards for monitoring such as SNMP protocol, WMI service or Cisco NetFlow methods. There are also described some other basic tools with open source licence used for monitoring. The main contribution of this thesis is clarification and subsequent usage of these methods for monitoring on VUT network. For this intermediation was used Nagios tool which used Nagios tool which provided feedback about the status of devices together with the own programmed plugin and tool Cacti which collected data from these devices and created graphical dependencies.

Comparison of Systems for Monitoring of Computer Networks
Vozdecký, Lukáš ; Kašpárek, Tomáš (referee) ; Čejka, Rudolf (advisor)
This thesis is comparison of three open--source Linux/Unix network monitoring applications Nagios, Zabbix, Big Sister. Every application is described according to its basic fundamentals. The comparison is done through managing series of tests based on real environment experience. Solution to these problems and specific procedure differencies are described for each application.

Analysis and Design of Information System MEDIMED
Lebeda, Martin ; Malinka,, Kamil (referee) ; Neuwirth, Bernard (advisor)
This work deals with the modifications of project MeDiMed, which ceased to meet the requirements it imposed. In the first part the main objectives, targets and methods to achieve them are defined. The second part deals with the theory that is needed to understand the issue. In the practical part, which is based on the theory is prepared SWOT analysis and the modified HOS-8 analysis of the current state, whose results are then analyzed. The next section presents design of new solution. The conclusion summarizes all the proposed solutions and knowledge that have been achieved in this work.

Enterprise Network Design and Simulation - Cisco Virtual Lab
Ollé, Karol ; Komosný, Dan (referee) ; Soumar, Michal (advisor)
Tématem této diplomové práce (dále jen DP) je návrh rozsáhlých podnikových sítí podle doporučení stanovených společností Cisco. Dále je realizována simulace navržené topologie prostřednictvím programů s otevřeným zdrojovým kódem a dohled nad sítí prostřednictvím programu Nagios. Úvodní část obsahuje stručné seznámení se základním rozdělením sítě do jednotlivých funkčních bloků. Druhá část se zabývá popisem jednotlivých funkčních bloků a jejich rolí v rámci celé síťové topologie. Bloky jsou dále rozděleny na jednotlivá zařízení a jsou popsány služby, které tato zařízení musí poskytovat. Třetí část DP se snaží zmapovat základní požadavky na služby, které jsou kladeny na dnešní síťové infrastruktury. Hlavní důraz je kladen na dostupnost všech nabízených služeb sítě. Jsou vyjmenovány jednotlivé protokoly druhé až třetí vrstvy OSI modelu, které zabezpečují stálou dostupnost sítě v případě selhání aktivních prvků. Čtvrtá část DP se věnuje popisu návrhu síťové topologie WAN. Pátá část obsahuje popis bezpečnostních rizik, která ohrožují dostupnost sítě, tak i popis útoků, které mají za cíl krádež identity uživatele. V šesté části DP jsou popsány programové nástroje pro zprávu sítí (Nagios, Cisco Security Device Manager) a programy, které simulují Cisco přepínače, směrovače (Dynamips & Dynagen, GNS3) a Cisco PIX firewall (PEMU). Sedmá kapitola se zabývá konkrétním návrhem rozsáhlé sítě s použitím principů, které byly zmíněny v předcházejících kapitolách. Navržená infrastruktura je dále realizována pomocí simulačních programů a tato virtuální síť dovoluje demonstrovat nastavení a chování všech popsaných protokolů a zařízení. V závěrečném shrnutí je nejdůležitější poznatek, že návrh a konfigurace rozsáhlé sítě a její realizace ve virtuálním prostředí je funkční a použitelná pro pokusné účely i pro studijní účely.

Monitorovací systém firemní počítačové sítě na bázi open source řešení
Vařacha, František
This bachelor thesis is concerned with extension of the existing monitoring system in a real business environment. The entire monitoring system is based on the open-source programs Munin and Nagios. In the practical part is explained the configuration and implementation of both of the programs and verification of the monitoring system in the form of tests.

Specifika informačního managemntu v síťové topologii
Buzek, Jiří ; Mildeová, Stanislava (advisor) ; Král, Miroslav (referee)
This work deals with programs designed to manage data networks and to their use in managerial practice. The purpose is to explain how these programs contribute to a systemic understanding of managed network and system thinking. All these methods are applied on example of two largest wireless ISP companies in South Bohemia. The dissertation explains the issue of making mental models of the managed network, which concerns specially managers of ISP companies. The work is not an administrator view at programs for network management, but rather a management view and instructions how to use these programs in management decisions to solve complex problems and future development of managed network.
