Nagios Support Forum

I notived that the changelog for Nagios XI 2014R2.1 release included some addtional config wizard - Added SLES, OpenSUSE, and CentOS/RHEL 7 support to the Linux Server config wizard (updated linux agent installer to work on the new systems) -JO

However, I upgraded and do not see them. Still just see the same 4 as before. Do I need to do something extra to get SLES config wizards?

What version of the wizard are you running? That might need to be updated separately. Admin -> Manage Config Wizards, check for updates.

1.4.1 is the version it looks like I am running.

I ran the update and I have quite few that have updates, one being 1.4.2 for the Linux one. Never knew that existed. Thanks.

Not a problem. Go ahead and run the update, see if they show up. If they do I will mark this thread as resolved and close it.

I tried to add the SLES 11sp3 LInux using the Linux Server Monitoring Wizard but after I cd /tmp and http://assets.nagios.com/downloads/nagi ... ent.tar.gz then tar xzf linux-nrpe-agent.tar.gz and cd'd to linux-nrpe-agent the ./fullinstall did not work. I received the message ERROR: Could not determine OS. Please make sure lsb_release is installed or your OS info is in /etc/os-release. SLES 11sp3 is using /etc/SuSE-release to provide OS information. Is there a way to change this or remove the check to complete the install for the nrpe agent?

I monkey'd around with the /etc/os-release so it just has NAME=SUSELinux instead of the defaults in /etc/SuSE-release:
SUSE Linux Enterprise Server 11 (x86_64)
VERSION = 11
PATCHLEVEL = 3

Ran the fullinstall from the nrpe download but encountered this error.
./fullinstall

Manually added the nagios group, not sure why the script didn't add it but added the nagioscmd group. Ran the fullinstall again and more errors. I think this needs worked on before you can say it supports SLES (SUSE Linux Enterprise Server).

Attaching the install.log file for reference.

I touched /etc/xinetd.d/nrpe and reran the fullinstall.

This time it looked a little better but I haven't validated the installation and will see if Nagios XI is able to report back the status of my checks shortly.

Adding the install.log again for reference but this is what I had to do:
Remove the -a in front of -G for the eval "$usermodbin" -G "$nagioscmdgroup" "$nagiosuser" and eval "$usermodbin" -G "$nagiosgroup" "$nagiosuser" lines of 2-usersgroups script.
Manually added nagios group, not sure why the script didn't add it.
Touched /etc/xinetd.d/nrpe

Ok, so I only get ping status everything else is showing (Return code of 255 is out of bounds)

I am not sure if you were able to successfully install the linux agent, but there is definitely a problem with the installer. It seems like the command, which can be used in almost all linux distros:
doesn't work in SUSE...

As a "workaround" you can try:
Then, try to run "./fullinstall" again.

Make sure that port 5666 is open. Test it from the Nagios XI server:
Hope this helps.
