I have added one hosts and everything is configured correctly in the remote host and also in the nagios server. But still it is showing plugins are missing. I have attached the snapshot of the error.

I have also installed nagios in my CENTOS system. In CentOS, it shows perfectly, but only in fedora it shows plugins are missing. Please help

the plugins need to be on the remote box, not the server.

Hi,

I have downloaded the file nagios-plugins-1.4.16.tar.gz and nrpe-2.14.tar.gz. I have extracted the two files. Then in nagios-plugins-1.4.16 folder, i have run the command from root as as ./configure --with-nagios-user=nagios --with-nagios-group=nagios
then next command as sudo make
and then sudo make install

everything went fine

But after extracting nrpe-2.14.tar.gz, i have run the command ./configure
and then in the nrpe-2.14 folder, there is no make file because I have to run the following commands

make all
make install-plugin
make install-daemon
make-install-daemon-config
make-install-xinetd

Since there is no make file inside the nrpe folder, how shall i run the make command, so that the plugins get installed??

Seeing as you're just getting started I would *VERY* strongly urge you NOT to use NRPE (I'd urge you not to use Nagios but that's too late!) use the check_by_ssh plugin instead, and then you don't need to set up any nasty insecure NRPE junk. Just put the scripts in a suitable location and call them via check_by_ssh. there is no need to "install" them, they're just scripts.

Could you, please, post your question on the official nagios support forum?

http://support.nagios.com/forum/index.php

This way your issue will get resolved a lot faster. Thanks!

Well seeing as he's not come back for a week, I don't exactly think the forum is the hold up here, IF there even is one. We're doing just fine here, thanks.

Really? Nagios was the clear winner of last year's poll on this site for monitoring with 10X the votes of the next closest monitoring software.

That said,

@rahul.buragohain

Based on your screenshot it looks like you have it installed correctly, you will just need to edit the path to your plugins in your nrpe.cfg at the bottom you should see something like

Code:

command[check_users]=/usr/local/nagios/libexec/check_users -w 5 -c 10
command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20
command[check_hda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/hda1
command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z
command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200

Make sure these are the actual paths to your plugins. Then if you make changes you will need to restart xinetd

Code:

service xinetd restart

Normally most plugins reside on the server and communicate with remote hosts via snmpd. No need for NRPE unless you really want to avoid snmpd or require some complex data extraction on the remote.

Hi,

All the configuration files are correct, but still I am getting the error as (Return code of 127 is out of bounds - plugin may be missing)

So can you run the plugin on the actual client machine? As Nagios is so ugly and clunky you can at least break into the chain of manual commands being executed, check what command is being run by the nrpe plugin and run it directly on the target, and then also run the check_nrpe commadn directly from the server.

Hmm, since when did someone in the open source, non-mainstream community think that pure popularity was a marker of quality? Please stop advertising your own commercial interests. Scott, if you wish to officially come here with your colleagues to drive traffic to your own business website, you should speak to Jeremy about the options that may well be open to you.

rahul.buragohain · 01-23-2013, 03:20 AM

Hi,

I have find out the error, and I have resolved. Thanks to all of u.

acid_kewpie · 01-23-2013, 03:22 AM

some feedback on what it was would be appreciated to potentially help others.

rahul.buragohain · 01-23-2013, 03:30 AM

Hi Chris,

As I have mentioned that it is 64 bit system, so I edited the file commands.cfg in nagios server as

define command {
command_name check_nrpe
command_line /usr/lib64/nagios/plugins/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -a $ARG2$
}

Initially the problem was that I was gving /usr/lib/nagios/plugins/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -a $ARG2$

Now I have edited and made /usr/lib64/nagios/plugins/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -a $ARG2$

And It worked. This is the way I solved.

ludmilmm, Welcome to LQ and thanks for your participation (note that we have an Official Participation program: http://www.linuxquestions.org/questi...-at-lq-612689/). That said, in the future we'd appreciate it if you'd please refrain from simply pointing to different forum without providing any other helpful information in the post. Thanks.
