Description-en: host and network monitoring system
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 is the metapackage to install all Icinga 2 features.
