Monitorovací systém IT infrastruktury založený na Sensu Go

This thesis is talking about designing and deploying monitoring system of IT infrastructure, which is based on open source software Sensu Go. The whole project was done using just open source technologies supporting a monitoring of IT infrastructure and the resulting solution is possible to deploy for monitoring on wide variety of parts of IT infrastructure. First part of the thesis is introductory, explaining the reader writer’s main driver behind this thesis ranging from plain interest to real case scenarios writer was facing. Following part is focused on analysis of current issues and their states, comparing already existing solutions and introducing different approaches to monitoring. Based on knowledge gained in previous chapter, we prepare our model for our monitoring system. In the next chapter we describe all parts of our model that cannot be absent in monitoring system and suggest for each of them the best fitting tools. While looking for the best fitting tools, our main criteria are that all of the tools must be freely available as open source as well as it must be possible to scale them. Important criterion for us is also that all our tools must follow some security practice. Followed by that is process of installation and configuration of our designed system. The main goal of this thesis is to introduce reader to the whole process of designing and deploying of monitoring system, what parts of the system are necessary and should not be forgotten and to share some knowledge based on real case scenarios.
