Monitoring Wizard - Configuration verification failed

[gbnag]

Hello,

We installed the nagiosxi Linux agent on Ubuntu14-04. Getting a 'Configuration verification failed' message after we finish going through the Linux Server Monitoring Wizard tool.

I verified that the nagios server can communicate with the target Ubuntu system.
-------------------------------------------------------------------------------------------

root@localhost-010049098179 ~]# nmap -p5666 gberger-ubuntu.qualcomm.com

Starting Nmap 6.47 ( http://nmap.org ) at 2016-08-26 16:05 PDT
Nmap scan report for gberger-ubuntu.qualcomm.com (x.x.x.x)
Host is up (0.011s latency).
PORT STATE SERVICE
5666/tcp open nrpe

Nmap done: 1 IP address (1 host up) scanned in 0.09 seconds
-----------------------------------------------------------------------------------

also verified that in ccm, tools, Write config files that there are no errors:

Write host configurations ...
Configuration file: gberger-ubuntu.qualcomm.com.cfg successfully written!
WARNING! Ghost host config detected! Removing the file oum-master.qualcomm.com.cfg
Host configuration files successfully written!

Write service configurations ...

Please advise

Thank you,

Can you run the following in an ssh session on your Nagios XI host.

Code: Select all

tail -f /usr/local/nagiosxi/var/cmdsubsys.log

Then go into XI and Apply Configuration.

What output is produced in the SSH session?

[gbnag]

reran the linux wizard and recorded the cmdsubsys, log file attached.

thank you

Bleow are the errors that are causing the verification error.

Code: Select all

Error: Could not find any host matching 'oum-master.qualcomm.com' (config file '/usr/local/nagios/etc/services/oum-master.qualcomm.com.cfg', starting on line 32)
Error: Failed to expand host list 'oum-master.qualcomm.com' for service '_um_ URL Status' (/usr/local/nagios/etc/services/oum-master.qualcomm.com.cfg:32)

If you go in to Core Config Manager and edit the service called '_um_ URL Status' and add a host to it, that should fix it for you.
If you don't need that service check, you can delete it and that would fix the error as well.

[gbnag]

that worked, thank you.

Now with the ubuntu system showing in nagiosxi, we would like to add some process daemon monitors. the processes have the same name but using different args.
I remember during our quickstart session we could not get it to discover due to the issue we just resolved.
what would be the correct sequence of steps to add these proc monitors to capture avail, cpu and memory util stats per process?

thanks in advance.

[Box293]

Can you give us an example. What are you doing in the wizard? Does the wizard fail?

[gbnag]

Actually, we can now see the ubuntu devices in nagiosxi but all checks are red, see attached CAPTURE.PNG.

[Box293]

Can you show us the service details of one of the services.

Also, go into CCM > Monitoring > Services
Click the disk icon and paste the text config here of that service.

Attached is the services screenshot, below is the disk config for the ubuntu system:

Usually this is related to permissions, please manually run a few checks against the client machine from the CLI, and while doing so look at /var/log/messages on the client machine. What error do you see returned?
