Plugins for Getting Information about the System for BusyBox
Poláček, Marek ; Konečný, Filip (referee) ; Vojnar, Tomáš (advisor)
In this thesis, we discuss implementation of tools for getting information from the system. We examine file systems sysfs and procfs in the Linux operating system. Furthermore, we discourse how to write small programs in the C language. Eventually, we take a look at implementation of tools like iostat, mpstat and powertop. These tools were implemented in a minimalistic form suitable for Busybox within this thesis.

Unix Tools for Application and System Profiling
Dressler, David ; Chalupníček, Kamil (referee) ; Kašpárek, Tomáš (advisor)
The main goal of this thesis was to demonstrate usage of tools for application and system profiling. Initially, these tools was found and studied. They was also divided into categories according to their purpose. After that, these tools was compared according to their complexity of use and invasiveness. As the result of this comparison, these tools was divided into three groups, that express measure of complexity and invasiveness. As technology, used for creating models, was chosen Apache server and NFS server. Virtualization by hyper-v technology was used for putting these models into operation. There was created four virtual machines. Fist one for Apache server, another one for NFS server. Third was for mirroring content of Apache server and the last one for load generation. The last part of this thesis was to demonstrate usage of found tools on the created models.

Extending RedirFS to Userspace
Pírko, Jiří ; Čejka, Rudolf (referee) ; Kašpárek, Tomáš (advisor)
The purpose of this thesis is to consider the rigth way how to make a user space extension of RedirFS, which works as a Linux kernel module and implement it. There is described a model of user and kernel spaces used in Linux and how this two spaces can communicate with each other. There are several communication mechanisms described with a description of use. Bandwidth and latency tests for all these mechanisms are implemented. Measurement results are presented and the suitable mechanism is chosen. The second part of the thesis is focused on redirctl and urfs. The first solution represents the RedirFS control tool, the second is the implementation of user space filters.
