Nagios is the standard open source monitoring system for automatic, continuous monitoring of even demanding IT infrastructures. The software displays the current status of all the recognised routers, servers, services and switches on the network via a web interface and can perform different actions when critical statuses occur, such as sending e-mails or SMS messages.
Many administrators also use Nagios to monitor function and utilisation of UCS-based servers, as Nagios facilitates the hardware-specific resource planning by compiling tendencies in availability.
With Nagios for UCS, the administration and use of this monitoring solution are performed via the UCS management system. Thanks to the seamless integration of the Nagios packages provided by Univention into the UCS management system, the Nagios-specific computer properties are administrated directly in the computer objects and not in separate configuration files. These Nagios packages configure the monitoring of the important services installed on a UCS system amongst other things.
This means, for example, that administrators only have to save a new server in the UCS management system once and then they can administrate all the properties such as IP configuration, installed software, system roles and services centrally. There is no need to set up Nagios manually.
Additionally, Univention supplies a range of Nagios plug-ins, with which UCS-specific services such as LDAP replication and LDAP notifications or the validity periods of SSL certificates can be monitored centrally. These plug-ins are also suitable for use with existing Nagios installations.
You will find futher detailed technical information about nagios in the Univention Support and Knowledge Base (SDB) (german language). Instructions are available in the Documentation area for its advanced configuration.
