Industrial log server with data visualization
Asszonyi, Jakub ; Holasová, Eva (referee) ; Kuchař, Karel (advisor)
The thesis focuses on the complex design, development and implementation of an industrial logging server with integrated data visualization. The aim of the thesis was to conduct a research of the current state of the art in the field of operational and industrial technologies. The thesis also deals with basic data processing and presentation, where an analytical search of open-source tools for creating REST APIs was performed. The work includes the implementation of an industrial network simulation using the industrial Modbus protocol. The industrial logging server was developed in the Docker virtualization environment and is structured into four basic parts: a REST API (FastAPI), a user interface (Next.JS), a database (InfluxDB) and a server agent providing communication between the industrial network and the server (Telegraf). Furthermore, the paper discusses the security of the industrial server both in terms of unauthorized access to the database and user interface, and in terms of access to the server from the industrial network. In the last part of the thesis, testing of the server efficiency and functionality of all implemented parts has been done.

Web application for monitoring computers in a computer network
Asszonyi, Jakub ; Člupek, Vlastimil (referee) ; Sikora, Marek (advisor)
This bachelors thesis describes design and implementation of web aplication for monitor- ing servers in computer network. The goal is to study web development form historical and current view. Next goal is to study network communication and DoS attacks, which is reason for writing this thesis. Application was developed in React.js framework, with node.js. The most important requirement was the least network traffic. For that reason there were implemented method which prefer lesser trafic over optimalization. Applica- tion is in working state, and can monitor servers in network.
