Extending icinga monitoring capabilities

Nagios and Icinga are very popular IT infrastructure monitoring systems. Several commercial systems are also based on or evaluated from them. The paper presents the experiences with Icinga in the Institute of Computer Science WUT. Practical usage revealed some system shortages related to many worthless plugins, configuration problems and the Icinga modules itself. They are addressed in this paper by some extensions developed towards deeper diagnostic analysis of the monitored systems and mobile and Internet of Things systems monitoring support.
