Monitoring and auditing computer equipment in a company

The thesis describes selection of an open source monitoring and auditing system for computer equipment in an enterprise, where the cost of same purpose commercial software is too high.Control systems (Nagios, Zabbix and Zenoss) and auditing systems (Open-Audit and OCS Inventory NG) for computer equipment are shortly presented first. Using the comparative criteria and our own testing we selected Nagios as the most suitable monitoring system and Open-Audit as the best auditing system in our case. Additionally both selected systems are described in detail, including the essential features of their functionality. Finally, we presented the development of a specific plugin for the control of a special device in the enterprise.A large number of plugins exist on the official site of Nagios, some written by the author of the Nagios system and others developed by other system users. Due to security policy of the enterprise existing plugins were not beneficial, thus we developed our own plugin
