Nagios Support Forum

Posted: **Mon Dec 17, 2018 5:58 pm**

We are needing to do a count on txt files in a certain directory and when there is more then 500 in that directory we need nagios to alert us via email. Here is what I have done, however what is the best way to do this?

On the remote server I created a script and put it here

Code: Select all

proxy4gl>pwd
/usr/local/nagios/libexec

Basically the script is basic and does the following.

Code: Select all

#!/bin/bash
#
# check /usr/rmca/doc_image/ directory for txt files
#
find /usr/rmca/doc_image/ -name *.txt | wc -l

I change the permission and group on the script and ran it as nagios and it seem to run fine.

Code: Select all

proxy4gl>whoami
nagios
proxy4gl>./check_files_txt.sh
110
proxy4gl>

I will add the command to the nagios server next. Please advise if this I am doing this correct. I have added the following to the nagios server

Code: Select all

command[check_files]=/usr/local/nagios/libexec/check_files_txt.sh

when testing from it I am getting this.

Code: Select all

[root@nag etc]# /usr/local/nagios/libexec/check_nrpe -H 192.168.1.12 -c check_files_txt.sh
NRPE: Command 'check_files_txt.sh' not defined
[root@nag etc]#

what am I doing wrong?

Thanks

Hi, @donnyforbes. I suggest using the following command instead:

command[check_files]=/usr/local/nagios/libexec/folder_watch.pl -T 'files' -D /usr/rmca/doc_image/ -F '*.txt' -w 480 -c 500

This should go on the remote nrpe server in the /usr/local/nagios/etc/nrpe.cfg file.

The command to run from the XI server will look like this:

/usr/local/nagios/libexec/check_nrpe -H 192.168.1.12 -c check_files

Thanks for getting back to me. Here is what I did.

Remote Server:
vi /usr/local/nagios/etc/nrpe.cfg

added the following ...

Code: Select all

command[check_files]=/usr/local/nagios/libexec/folder_watch.pl -T 'files' -D /usr/rmca/doc_image/ -F '*.txt' -w 480 -c 500

Ran the following command on the Nagios server and got the following error message.

Code: Select all

[root@nag etc]# /usr/local/nagios/libexec/check_nrpe -H 192.168.1.12 -c check_files
NRPE: Unable to read output
[root@nag etc]#

Also I did stop /start the xinetd service on both servers.

What am i missing ? Thanks for your help..

I did a a search for this folder_watch.pl in the /usr/local/nagios/libexec directory and that was not there.
Is this something I need to download or is this on the XI interface?

Posted: **Tue Dec 18, 2018 4:56 pm**

I did check on the Nagios XI and I do see the plugin there, also on the Nagios server NOT remote server I do see the following

folder_watch.pl

Do I need to add this command

Code: Select all

command[check_files]=/usr/local/nagios/libexec/folder_watch.pl -T 'files' -D /usr/rmca/doc_image/ -F '*.txt' -w 480 -c 500

To the nagios server or the remote? I have it added on the remote server as of now...

Please advise .

@donnyforbes, Sorry I wasn't aware that this plugin doesn't come with nrpe by default. Please use WinSCP or FileZilla to copy over the plugin from the /usr/local/nagios/libexec folder on the nagios server to the same folder on the nrpe server.

So copy the plugin from my nagios server to the remote server is that what you are asking me to do?

Ok this worked see below.

[root@nag libexec]# /usr/local/nagios/libexec/check_nrpe -H 192.168.1.12 -c check_files
OK - 0 *.txt files found
[root@nag libexec]#

Is says 0 found, however when i run this command on the remote server ... I get this

Code: Select all

proxy4gl>find /usr/rmca/doc_image/ -name *.txt | wc -l
110
proxy4gl>

Is something not correct? So one says there 110 and the other ones says there is 0. Any ideas?

@donnyforbes , Can you run ls -lR /usr/rmca/doc_image/ and show me the output?

Posted: **Tue Dec 18, 2018 5:42 pm**

Sure here you go.
