Nagios Support Forum

Hi Forum,

"Linux-Server" wizard is not getting installed - Please check details below:-

Nagios XI server details :-

[root@server nagiosxi]# uname -a
Linux naggy 2.6.18-274.el5 #1 SMP Fri Jul 22 04:43:29 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux
[root@server nagiosxi]#



I have installed the NRPE agent on the client machine (please check the notepad attached) successfully.

Client machine:-

[root@server1 linux-nrpe-agent]# uname -a
Linux server1 2.6.18-238.el5 #1 SMP Sun Dec 19 14:22:44 EST 2010 x86_64 x86_64 x86_64 GNU/Linux
[root@server1 linux-nrpe-agent]#




But "Linux-Server" wizard is not getting installed. I have downoaded the "Linux-server" wizard from the below link
http://exchange.nagios.org/directory/Ad ... rd/details

and followed the steps mentioned in "Installing_XI_Configuration_Wizards.pdf", when i click the upload button - the screen shows me Wizard Installed, but i am not able to see anything under the list - please check the print-screen in the word document attached.

I even tried to installed "Esenors-websensor" wizard and same thing is happening with this wizard as well.


May i request you to please help me in this configuration as I have to show them the DEMO on this Friday (24/02/2012).

Awaiting prompt reply.

This sounds like a permissions problem.

Please run the procedure from the following file and let me know if the problem persists
http://assets.nagios.com/downloads/nagi ... ios_XI.pdf

If you still cannot upload a wizard, please send back the output of the following

Try going to:

Admin->Monitoring Config->Check File Permissions
and
Admin->System Config->Reset Security Credentials->Update Credentials

Then try to reinstall the wizard. If it is still not working, try resetting your global permissions, following the steps outlined in this document:

http://assets.nagios.com/downloads/nagi ... ios_XI.pdf

Let us know if this helped.

Hi Tech Support,

requesting prompt reply

Many thanks for your great support.

Actually, the nrpe installation log doesn't look like everything went ok...

toward the bottom you have several items showing that it couldn't read the file /etc/xinetd.d/nrpe

Do you have one? If not, this will be the problem

We need one, and we need it to look like this Then restart xinetd

Hi Tech team,

I have made the changes in the client , but still Nagios XI GUI is showing "connection refused by host" - same printscreen which i posted yesterday.
Please guide further.

[root@comedian xinetd.d]#
[root@comedian xinetd.d]# cat nrpe
# default: on
# description: NRPE (Nagios Remote Plugin Executor)
service nrpe
{
flags = REUSE
socket_type = stream
port = 5666
wait = no
user = nagios
group = nagios
server = /usr/local/nagios/bin/nrpe
server_args = -c /usr/local/nagios/etc/nrpe.cfg --inetd
log_on_failure += USERID
disable = no
only_from = 127.0.0.1 82.132.153.131
}

[root@comedian xinetd.d]#
[root@comedian xinetd.d]# service xinetd restart
Stopping xinetd: [ OK ]
Starting xinetd: [ OK ]
[root@comedian xinetd.d]#

Can you run the following on the nrpe client machine We want to see if there are NRPE errors showing up there.

Hi Tech team,


can you please also guide me for the Solaris Nrpe Agent link & which Wizard i have to install for Solaris? - I am not able to find the proper link for them.


Best regards,

Looking back at your nrpe-agent installation-- log.txt it looks like much of the install failed...

Is the a RHEL machine? Is it registered with RHN?
