Nagios Support Forum

I've got 4 fused servers in Fusion.
2 core 2 XI
All use AD auth and are setup to use the same AD account as a nagios read only account for Fusion.

One of the fused servers stopped connecting.
By that I mean the Tactical Summary on Fusion, which shows each server, now lists 0's for that 1 fused server.
It was showing the information (up/down/etc.) for that server ... though I'm not sure when it stopped showing it (I don't go into this interface much)

Configure->Fused Server Credentials-><server > shows OK, as do the other fused servers.

I verified that I can indeed log into that server using the account/pw.
I changed the username / password here, no difference.
I removed the server from Manage Fused Servers and then readded it, no difference.

From Home -> Servers I can click on the server and it launches.

Is the server that "stopped connecting" a Nagios Core or Nagios XI server? Do you see any issues in regards to this server in the "/usr/local/nagiosfusion/var/poller.log"? Have you tried restarting crond?

It's XI.

Code: Select all

service crond stop
killall crond
service crond start

On the Fusion box or the XI box?
The Fusion box has been restarted and I manually restarted crond on the XI box .. though all of it's other cron stuff was ticking along fine.

On the Fusion box or the XI box?

I meant Fusion - sorry I was not clear enough.
What is the name of the "problem" server? Can you post the "/usr/local/nagiosfusion/var/load_url.log" and the "/usr/local/nagiosfusion/var/poller.log"?

I can see there's *something wrong ...

Just so we know we are looking at the right things on our end, can you clarify the versions of Fusion, XI, and Core that are in play here?

Fusion: 2014R1.1
We've got a mix of core and XI versions
The problematic ones (there are actually 2)
OIT-XI
5.2.7
Tactical Overview shows "Monitoring Engine Disabled" (it's not)
OIT-Core
4.1.1
Tactical Overview shows " Unable to find the required Nagios Core XML CGI."

We have 2 successfully fused core servers that are 4.1.1 and 1 that's 3.5.1
The other successfully fused XI server we have is 2014R2.5

Looks like your fusion server is getting a 404 when trying to access the information, if you go to this URL in the web browser, does it show proper data?
Did they do any apache hardening on that server? (Changing allowed ciphers or allowed protocols like TLS/SSLv2/SSLv3).

Please run this command from your Fusion server and post the output:
- Make sure to set the username and password in the URL as well
Also, this:
Thank you

Oh, actually, edit the XI server in the Fusion web interface and change it from:
To:
OR if it's an XI server:

That resolved the issue with OIT-core (oit-nagios) - TNX.
Neither of those commands worked for the either of the XI servers though.
