Abstract:
Nagios is a widely used open source network monitoring system. It enables administrators to continuously monitor hosts and services on the network. Through a web interface administrators are able to watch the state of monitored entities. However, an administrator can not only watch problems, but also handle them in an easy way, for example he acknowledges a problem or adds a comment. In that way it can be avoided that unintentionally multiple persons work on the same problem the same time. The growing distribution of the operating system Android for mobile devices (smartphones, tablets) opens up the possibility to bring the user interface of the network monitoring system still closer to the administrator: It is no longer necessary to constantly monitor the web interface at a computer. When problems arise, mobile devices can alert automatically (e.g. by sound, or vibration). The developed software "Androgios" displays the main features of the Nagios web interface on Android devices. Through the use of Androgios users can inspect both hosts and services. Overview lists of all monitored entities can be displayed. These lists can be filtered to e.g. only display problems. In addition to overviews there is a detailed view for each monitored entity available. Androgios also supports to send external commands such as acknowledging problems or adding comments. Changes in the configuration of the Nagios server are not necessary.
