Agent On Oracle VM server release 3.2.3

[abrist]

Does it have access to the internet though?

[Errno 4] IOError: <urlopen error (-3, 'Temporary failure in name resolution')>

It is failing name resolution to the repo servers. . . .

[cokj72]

try again, today I made ​​the 'upgrade to version 2012R2.5 and I have a problem with the Oracle server monitoring

The issue you were seeing was with installing the agent on the host oracle VM's correct? So upgrading Nagios XI would have no effect on this.

This output from install.log after linux-nrpe-agent/fullinstall

*** Compile finished ***

If the compile finished without any errors, you should
find client and server binaries in the src/ subdirectory.

Read the README file for more information on installing
the binaries, creating configuration files, and using
the server and client.

You are still having massive repo issues. Is this connected to the internet?
The xinetd installation most likely had an issue. What are the permissions on:

Code: Select all

ls -la /etc/xinetd.d/

Did you run the ./fullinstall script as root? It looks like the agent did not install the necessary nrpe definition for xinetd.

Did you run the ./fullinstall script as root? It looks like the agent did not install the necessary nrpe definition for xinetd.

Yes, I use user = "root".

[abrist]

Lets check the services file required by xinetd:

Code: Select all

cat /etc/services | grep 566 | grep -v '#'

If the above command does not output something similar to:

Code: Select all

nrpe         5666/tcp
nsca         5667/tcp
ndo2db    5668/tcp

You will need to add the above entries to the file.
Additionally, the contents of the file:

Code: Select all

cat /etc/xinetd.d/nrpe

Should be:

Code: Select all

# 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       = 127.0.0.1 192.168.74.134
}

As that file most likely does not exist, you will need to create it and copy the above text into it.
Afterwards, restart xinetd:

Code: Select all

service xinetd restart

[cokj72]

Ok, I' have create the file:
/etc/xinetd.d/nrpe

Start the service:
[root@ovmn xinetd.d]# service xinetd restart
Stopping xinetd: [ OK ]
Starting xinetd: [ OK ]

But created agent from GUI "Linux Server" I receive:
Connection refused by host

I followed the procedure "NRPE Troubleshooting and Common Solutions" in step 3, but the problem persists, I have not run the "SSL not compiled in:" because I do not have directory:
/tmp/nrpe-2.14
but:
/tmp/linux-nrpe-agent
--
for the procedure in step 4, I do not have the file:
/usr/local/nagios/libexec/check_nrpe
