Nagios Support Forum

Hi, I just want to get some clarification. Should I install Fusion on one of my current Nagios XI servers or would it be better to put up another Nagios XI server to run only Fusion and not monitor other servers.

Thanks.

Fusion runs with a pretty low CPU overhead, so as long as you're trying to push a Nagios XI server to the absolute max for performance, you can install it alongside of an XI installation.

Thanks, I have installed in on one of my XI servers, but now I am having some other difficulties...

I have added 4 servers. The one that fusion is running on is OK, but the other 3 have " Unable to parse Nagios XI server response." in the Tactical Overview.
Any ideas? These are at remote locations, but port 80 is open and I can login to each XI instance in a browser from the location where Fusion is installed. Is there a timeout threshold? Some of these remote XI servers are quite a distance away with 100-300ms latency.

Thanks.

There are timeout thresholds, but they're pretty forgiving. Can you check to make sure in the Admin panel that the authentication type is set to "Session" and not "basic"?

It is set to session, but I see the AUTH BAD error. I have verified several times that the password I supplied is correct. I can open the XI consoles with the same password in other tabs. Any clues? I have attached a SS.

Are any of the servers using NAT, Proxy, or SSL?

nope. just remote locations. going through a private cloud, no vpn, nat, or proxy. They are going through firewalls, thats why I asked if anything needs to be open beside port 80.

Just out of curiosity, what version of Fusion are you running?

Do these XI servers go through some redirects to access them?

If you want I can find the code to increase the timeout thresholds and we can see if that resolves the issue. I think the timeouts are set to around 10 seconds, but it's always worth a try.

It is a new install, so it is 2010R1.1 and the update page says I am up to date.
From the fusion server, traffic goes out a Cisco ASA through the private cloud of my ISP (a few router hops), through the remote site's Cisco ASA and to the Nagios XI server.

10 seconds should be plenty of time. Like I said, ping latency is sub 300ms. That error in the Tactical Overview comes up within 2 seconds.

Ok, let me do some code hunting to see if I can find some clues on that. It's probably something small that we're missing, but that's usually all it takes ; )
