building a large scaled monitoring system for a customer with icinga 1.4.0 + pnp4nagios 0.6 (bulk mode with npcd), db logging. it will monitor very different stuff …. from servers to network, from esx(i) to linux machines, from firewalls to printers … good to see that all the needed software comes from the debian stable repositories (non-free). once again debian FTW !
