Obviously this is more expensive than just buying a book, but it's more interactive and would pretty much equip you to be able to do whatever you ever needed to do with Nagios.

Re: [Nagios-users] What the best way to monitor Windows?
That's exactly what I do. I have a medium sized environment with 200+ Windows servers to manage. I have NSclient++ on every windows host, using a CNAME monitor and have a NSC.ini already configured and dropped into place. Works like a charm. With this method, I can also have check_nt, and check_nrpe if needed. On Fri, Aug 5, 2011 at 8:41 AM, Mathew Walker lmw94...@hotmail.com wrote: With NSClient++, you can easily copy the INI file around. for NRPE and NSClient++ config files I always put in 3 generic names as allowed hosts ... nagios1.domain.local, nagios2.domain.local, nagios3.domain.local. Those 3 are CNAMEs to my actual nagios systems so I don't have to worry about updating config files if I'm testing a new plugin on a test Nagios box, migrating, etc. Only downside is that it does require good DNS and you have the normally trivial overhead of that DNS lookup. -- Mat W.

Ok, so it sounds like there might be 3 best ways to monitor Windows in general. I will have to check them out in detail before deciding which way to go. I do note that the following though from reading about them - 1. Checkwmiplus - I switched from NSclient++ to checkwmiplus, because agent less monitoring gives me a more flexible nagios environment : - not needing a remote agent makes migration NAGIOS to another server easier, because usually because of security reasons, you will be configuring the agent to allow connections from a particular (NAGIOS) server only. - an agent needs to be extra installed on the windows server; that may seem 'easy' ; but it isn't if you are in a large IT group where people carry different heads, and things like 'convincing debates' and 'overal installation procedures' come into place. - there are disadvantages too : checkwmiplus has increased the cpu load on my nagios server dramatically because of the combined use of wmic and the perl-based checkwmiplus script. And multiple instances are running all the time for a large number of servers. I think I will have to migrate to a speedier nagios server in the future - checkwmiplus is still under very active development which has pros and cons; pros because of the active interest of the developer, cons because active installation components are still being changed, making upgrading and followup on versions a little bit more cumbersome and time intensive , then for nsclient++ , which ,already, much more stabilized.
