Nagstamon is permanently visible on your desktop to give you an overview about your network status as a freely floating desktop statusbar, easy to place wherever by drag and drop. Alternatively it may stay in the systray.
The statusbar automatically updates and shows a quick summary and a more descriptive status overview when moving your pointer over it. The status is indicated by different customizable colors for down/unreachable hosts and warning/critical/unknown services. Additionally it displays hosts'/services' status with icons if there are any special flags like "acknowledged", "downtime", "flapping" and "passive".
The context menu provides fast access to monitor page of failed services/hosts and to any remote service like SSH/RDP/VNC running on a host by clicking a service/host at the status popup. Additional custom actions could be defined easily for calling local/remote commands, opening certain web pages or start an action via URL.
The settings allows filtering hosts and services by category and with regular expressions.
The user gets notified by sound and flashing statusbar.
Supported server types are Nagios, Icinga, Opsview, Centreon, Op5 Ninja and Check_MK Multisite.
