Remote Monitoring - Windows Servers

[superhik]

Hi,
I'm fairly familiar with basic Nagios setup and have used it in my previous company to monitor LAN/servers. Configuring Hosts, templates etc.
I have now changed company and would like to implement Nagios to monitor multiple sites which have windows servers and are behind firewall.

Setup would be [Nagios server (public IP)<>Internet<>Firewalls<>Windows Servers]

Is there any simple guides on using Hosted Nagios (public IP) to communicate with NSclient, I just need to guidance on what needs to be done on Server Side and client sides.

Thanks in advance

If your firewalls at each end support site to site tunnels you could easily monitor all the servers using NSClient++ as the tunnels would handle all the routing. Might get complicated if you're monitoring more than one customer.

Without any tunnels, you could use one NSClient++ machine and proxy the checks for all the other NRPE machines, I did a write up about it here:

Or you could use Mod-Gearman and have worker(s) at each site executing the checks, would only need the Mod_Gearman ports open. Here's some Mod-Gearman info:

You could use passive checks like NSCA via NSClient++ which means the clients will be sending the results in, you then only need to open the inbound port for NSCA traffic. Here's a guide:

You need to work out what you want to monitor and what your restrictions are, this will help with your decision making.

Thanks, amazing guides! I will try passive checks NSCA route, basically for now just need to monitor that servers are live nothing complex for time being.
This info is exactly what I needed.
