Icinga

Icinga is developed by an international group of open source monitoring specialists and has its roots in Nagios. Icinga can monitor all facets of any IT infrastructure, including hardware, various operating systems and applications. Anything with an interface can be integrated into Icinga, including pre-existing monitoring tools and scripts. In this way, Icinga can be implemented as a standalone monitoring system or as an umbrella application that provides an overview of the entire IT environment. 

OlinData has partnered with the Icinga project and shall soon offer training and consulting in Icinga in Asia & Europe.
