 Nagstamon is a Nagios status monitor which takes place in systray or
 on desktop (GNOME, KDE) as floating statusbar to inform you in
 realtime about the status of your Nagios and some of its derivatives monitored
 network. It allows one to connect to multiple Nagios, Icinga, Opsview,
 Centreon, Op5Monitor, Checkmk Multisite, Thruk, Zabbix and Zenoss servers.
