What is the latest version of Fusion and how many XI instances can be mapped on it? Is there any limitation we have on adding xi servers?

The latest version of fusion is 2014 R1.0, released on 06/03/2014. There is no hard limitation that we have found, however, you may want to test it in a VM where you can provide more resources relatively easily if you plan on fusing more than 5-10 servers on it, the poller may have trouble keeping up depending on that, and the amount of users using it at once.

We are looking to have 300 XI servers to monitor 60000+ systems. This is a very large enterprise. What would you recommend for hardware requirements for Fusion and how many of them will we need.

Well, I can tell you that you are going to want quite a bit of oomph behind the fusion server, I'm not quite sure how it will handle 300 fused servers to be honest. Will you be having multiple XI servers pointing up to centralized ones? If so, that 300 number could go down quite a bit when talking about what fusion is actually going to be querying.

I did not get the point. Can you please explain?

do you mean to say centralized server as Fusion server or XI server?

I will be having 300XI servers on which we will be monitorig 60K+ nodes. To manage XI servers, was looking for Fusion server.

What will be the hardware requirement for Fusion server to handle XI servers? If single fusion server is not able to handle all 300+ XI servers then how many Fusion servers are reqired?

We haven't tested Fusion with so many fused servers, but it is probably possible to do the job with only one Fusion server as most of the "hard work" is done on the Nagios XI boxes. It is hard to know for sure as there are many other factors in place. However, if you are purchasing so many Nagios XI instances, most probably you would have a site-wide (as this will save you money). Each site-wide comes with a free Fusion, so if you had 5 site-wides, you could use 5 Fusion servers. This should be sufficient. Hope this helps.

Thanks for your help.

we have 60,000+ hosts with aproxamently 30 monitors on each host. How would you monitor the environment with XI, What would it look like? How many servers per Xi? What would the size of XI Servers be?

If we have answered your initial Fusion question, I would like to close this thread as you have opened another one for the same question here: http://support.nagios.com/forum/viewtop ... 69#p120269
