Nagios XI (5.2.9)

uname -a
Linux wudesktop 4.4.0-36-generic #55-Ubuntu SMP Thu Aug 11 18:01:55 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

64bit

VMware Image or Manual Install of XI?
I have this ubuntu 14.04 LTS installed under Oracle's virtual box and is a client to be monitored.

Are there special configurations on your system, ie; is Gnome installed? Are you using a proxy? Are you using SSL?
At one time I had this client acting as a Nigios Core 4.x monitor server. And I did remove.

I get the install to the client information from the Nagios XI gui when I go to setup "Configuration Wizard: NRPE - Step 2" and follow steps
"Agent Install Instructions:"

Seems I'm getting a ssl error ( i think )... I will aslo provide the entire install.log

Are you trying to install the Linux agent on your Nagios XI server?! You are supposed to install it on the client (machine that you want to monitor)... Also, Nagios XI is supported ONLY on RHEL/CentOS systems.

https://support.nagios.com/kb/article.php?id=12

Currently, Ubuntu is NOT supported.

no was installing NRPE agent on client and client is ubuntu. I have Nagios XI installed on a CentOS.

I will have to discuss this with our developers. I haven't been able to recreate the issue. I just installed the Linux agent (NRPE + Nagios plugins) on Ubuntu 16.04, and didn't have any issues...

Subcomponents installed OK
RESULT=0

In your initial post, you say:

I have this ubuntu 14.04 LTS installed under Oracle's virtual box and is a client to be monitored.

but in the install.log I see:

Nagios Linux Agent Installation Log
===================================
DATE: Sat Sep 17 11:01:56 PDT 2016

DISTRO INFO:

Can you confirm the Ubuntu version?

I know that NRPE installs fine on Ubuntu 14.04. I haven't tested installer on 16.04 up until today, but it seems to work fine, at least for me.

duh, yes I upgraded and posted incorrectly, it is Ubuntu 16.04

Post the output of the following commands:

Code: Select all

lsb_release  -si
lsb_release  -sr
cat /etc/os-release

Try updating the system:

Code: Select all

sudo apt-get update

then rerun the full install script:

Code: Select all

./fullinstall

If the full install fails again, post the "updated" install.log.
