Nagios Support Forum

Hi Team,

We have got a requirement to monitor an environment which has close to 1400(500 Prod, 700 non-prod & 200 DR) servers on multiple platforms (Windows, AIX 7 & Ubuntu). I have attached a rough draft of the architecture we are planning to implement, please suggest if we are in the right direction or do we need to take care of anything while designing a distributed environment. Also, Let us know the firewall ports that need to be opened on the firewall to pass the traffic.

That looks good, are you looking to share a single DB between your two DR servers??

Actually the DR instance will have XI to monitor DR servers and also have a db which collects perf stats from DR and the 2 non-prod xi instances. Updated Arch.diagram attached.

This seems to be in order. Something you may look into would be the addition of mod_gearman workers for your hosts so you can strain more performance out of the:

Should the worker system also have nagios core/xi instance??

No, you do not need a nagios server for your worker servers if you go that route, as the documentation shows.

Can we setup 2 workers on the same server? if yes, how. In addtion can we configure a worker to accpet traffic from 2 nagios worker servers(or can we specify the ip addresses of 2 modgearman servers when we asked to enter the ip of the nagios master server).

Yes you can control the number of workers that spawn through the worker configuration file, and you should be able to point two nagios addresses to a worker server. More advanced configurations not shown in our installation doc should all be covered here:

In the above archituecture what all ports should be open to allow the traffic to and from the fusion server and non-prod XI instances as we have a firewall between prod and non-prod environments.
Also, if we offload the database, will that offload the rrd's as well? Can you please help me understand what all information is stored on the mysql DB?

You should only need ports 80, and 443 (if using ssl) open in order to connect to the XI servers from Fusion.
