Icinga 2 is a general-purpose monitoring application to fit the needs of any size of network. icinga 1.x was a nagios fork; this new generation has been rewritten from scratch in c++, with multi-threading and cluster support.

features:
* all standard features of icinga and nagios;
* much faster and more scalable than icinga 1 and nagios;
* new, more intuitive, template-based configuration format;
* monitoring services on icmp (ping) or tcp ports (http, nntp, pop3,
smtp, etc.) by executing checks (see monitoring-plugins*);
* any small script following the nagios plugin api can be used as a
check plugin;
* notifications about alerts for any custom script (with examples);
* native support for livestatus and graphite.
this package provides configuration and some basic helper scripts.
