Nagios is and can be a centralized monitoring/alerting system. You need those dependencies on the host for it to run, but not on each host you want to monitor. Once you get it installed, you can make checks with SSH or run a "client" on each server, including windows.
The thing I really like about nagios for adding new host, is that once you get all of the config files templated, you can write scripts that easily add new host and "reconfigure" the nagios app. it's not dependent on a web interface (looking at you groundworks) or any other bells and whistles. bb On Fri, Mar 22, 2013 at 9:52 AM, Edward Ned Harvey (lopser) < [email protected]> wrote: > I've used zenoss before.
