The thesis deals with server monitoring, focusing on the server logs and storage devices in the form of modules into the KNOTIS information system. An administrator is warned of unusual activities or possible disk failures that may lead to data loss. It describes automatic data collection, data processing and user interface that is developed in the web environment and allows you to set different server monitoring parameters. SMART technology has been used to obtain the status of disk units. The thesis works with the use of disk arrays and LVM technology. It monitors also the most important server logs, such as auth.log, syslog, kern.log and apache's log files.
