I had downloaded the nagios-5.7.2-64.ova image and I am running that on a Windows 10 Enterprise laptop using VMware Workstation.

After initial setup I was trying to deploy my first agent on a Linux box running SUSE Enterprise. I entered the address, selected the OS type, entered my root credentials into the form but then I only got an error page stating:

FAILED - MODULE FAILURE See stdout/stderr for the exact error.

The console of the NagiosXI VM shows nothing. What stdout/stderr is meant here? How can I find out, why that agent installation failed?

Run the following while you try to deploy again:

Code: Select all

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

It should show you something like:

Code: Select all

CMDLINE=php /usr/local/nagiosxi/scripts/deploy_run_job.php -j '3'
OUTPUT=
RETURNCODE=4

Try running the CMDLINE directly on the command line of the XI machine as nagios:

Code: Select all

su - nagios 
php /usr/local/nagiosxi/scripts/deploy_run_job.php -j '3'

The number passed with the -j argument will likely be different. Make sure to use whatever was logged int he cmdsubsys.log file.

Already the tail fails. There *is* no such file. Which - I presume - indicates, that already the login fails. Even though I am sure to pass it the exact credentials I am using myself to ssh into the box. And - yes - that's a login using uid&pwd, not using any keys.

Can one trigger the script (or whatever is executed by that form) manually? I tried to peek into the .php script and wanted to single-step it but that seems to be compiled or something. It's not readable text...

I then found the following summary:

Code: Select all

                    },

Does that bring us any further?
Sigh! I though I was going to install a monitoring tool, not debug a monitoring tool...

HI,

Looking over that log output, you might be hitting this issue:

https://lists.opensuse.org/opensuse-bug ... 04383.html

Let's try to install python-xml on this host, and let me know if that resolves the issues.

https://software.opensuse.org/package/python-xml

Otherwise, let us know what version of Enterprise SUSE you're using so we can try to replicate this on our end.

Thanks,
Benjamin
