In most medium and large companies, the monitoring of temperature in rooms containing servers and networking equipment is required. The number of rooms can quickly reach 50 or more, which means a significant funds must be spent on monitoring hardware and software. The goal of this diploma thesis was to implement a straight-forward and cost-effective IT infrastructure monitoring system for automatic surveying and display of temperature in different rooms. The hardware part of our solution is based on the Rasperry Pi while the software part uses the SNMP for communication and Nagios Core for monitoring. The final result allows a user to view the history and current temperature for multiple devices. The system also supports the notification of users via e-mail.
