= Introduction =

The QCG platform provides Nagios plugins that enable any Nagios deployment to monitor a QCG platform as a whole and each component individually.

'''IMPORTANT:'''
In the case of EGI, Grid service monitoring is provided by the EGI SAM framework, which includes a Nagios instance and all necessary monitoring plugins bundled with it. Thus the QCG Nagios plugins will be shipped with the EGI SAM system, not with QCG platform components.
