DNX is designed to address pretty much what you're asking for there. Being the current lead developer on DNX, I am seeing it handle 3000+ hosts and
30,000+ services, all using just 3 boxes and we haven't even begun to saturate
CPU or memory so we know we can go a lot further. You should give it a shot, if you have any questions feel free to ask us on the
dnx list dnx-...@sourceforge.net (to prevent spam, sign up is required before

Enjoy!

Sincerely, Steve

Hi Ethan,

First, thank you very much for Nagios.

Our enterprise relies heavily on it and Nagios has been a great monitoring tools for us for so many years. Up to now, nothing has surpassed its simplicity of use and we will continue to use it in the foreseeable future.

As an enterprise looking to scale Nagios to tens of thousands monitored hosts and services, what could be our expectations of the future regarding scalability?

We are using NDOutils to centralize host/service status.

One of our main challenge will be to optimize the configuration and patch Nagios/NDOutils to make reloads as fast as possible since addition and removable of monitored hosts have a high turnover rate. (I don't know if it's the correct way to say it in English)

Reloading Nagios so it can pickup the new configuration is viewed as a "flaw" by our developers team because there's no monitoring done during that time.

If we reload Nagios too often, it would simply pass the majority of its time exporting configuration/status to NDOutils and scheduling checks without doing any real work at all. Too seldom and new monitoring would take too much time before being scheduled.

Any future plan regarding this aspect?

Also, have you ever heard of DNX? http://dnx.sourceforge.net/ Any future plan about a similar feature within Nagios?

Thanks for your time.
