Check number of files on a directory

Postby cocoyanouck » Thu May 11, 2017 8:03 am

Hello,

One year ago, I asked your helped in order to monitor a directory and send me a notification if there is too many files.
(https://support.nagios.com/forum/viewtopic.php?f=7&t=37972)

Today, I need to implement the same thing in a nagios 4 server on our site in China. But I have another problem :
https://img4.hostingpics.net/pics/319719Capturedecran20170511a160956.png

On commands.cfg :
# 'check_nrpe' command definition
define command{
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -a $ARG2$
}


On windows .cfg under others services :
define service{
use generic-service
host_name wamp03.snfchina.com
notification_interval 20 ; Resend notifications every 20 minutes
service_description Number of files on faxin
check_command check_nrpe!check_files!path='D:\\import\\faxin' pattern=*.* 'warning=count>100' 'critical=count>150' top-syntax='${status}:${problem_count}/$(count} files' 'empty-state=ok'
}

# Configuration file /usr/local/nagios/etc/objects/windows.cfg
# Edited by PyNag on Mon Feb 20 09:08:47 2017

define service{
use generic-service
host_name wamp03.snfchina.com
notification_interval 20 ; Resend notifications every 20 minutes
service_description Number of files on faxout
check_command check_nrpe!check_files!path='D:\\import\\faxout' pattern=*.* 'warning=count>100' 'critical=count>150' top-syntax='${status}:${problem_count}/$(count} files' 'empty-state=ok'
}

# Configuration file /usr/local/nagios/etc/objects/windows.cfg
# Edited by PyNag on Mon Feb 20 09:11:47 2017

define service{
use generic-service
host_name wamp03.snfchina.com
notification_interval 20 ; Resend notifications every 20 minutes
service_description Number of files on cmds
check_command check_nrpe!check_files!path='D:\\import\\cmds' pattern=*.* 'warning=count>100' 'critical=count>150' 'empty-state=ok' top-syntax='${status}:${problem_count}/$(count} files'
}


Kind regards,

It looks line the check_nrpe command is corrupted and to find out, can you run the following commands as root and post the output?
Code: Select all
ls -l /usr/local/nagios/libexec/check_nrpe
/usr/local/nagios/libexec/check_nrpe -V

Run this as well but change the xxx.xxx.xxx.xxx to the IP address if the Windows System.
Code: Select all
/usr/local/nagios/libexec/check_nrpe -H xxx.xxx.xxx.xxx -c check_files -a path='D:\\import\\faxin' pattern=*.* 'warning=count>100' 'critical=count>150'

It looks like the plugins permissions are correct and it can run without any command line options without segfaulting.
It could be that the NSClient++ service on the Windows system is returning something that is causing the plugin to crash so if you can post the nsclient.ini and the nsclient.log file here, we can check the settings and also any errors.

Re: Check number of files on a directory

Postby tgriep » Mon May 15, 2017 10:38 am

In this folder on the Windows host D:\import\faxin what do the names of the files look like?
If they have any special characters in them, that could cause the NSClient++ service send bad information when the check_nrpe command is run causing the segfault.

Lets raise the log level for the NSClient log file.
Edit the nsclient.ini file and under this section
Code: Select all
[/settings/log]

Change this option from
Code: Select all
level = info

to
Code: Select all
level = debug


Save the file and restart the NSClient++ service.

Then run the following commands on the Nagios server but change the xxx.xxx.xxx.xxx to the IP address if the Windows System. Post the output.
Code: Select all
/usr/local/nagios/libexec/check_nrpe -H xxx.xxx.xxx.xxx
/usr/local/nagios/libexec/check_nrpe -H xxx.xxx.xxx.xxx -c check_files -a path='D:\\import\\faxin' pattern=*.* 'warning=count>100' 'critical=count>150' top-syntax='${status}:${problem_count}/$(count} files' 'empty-state=ok'

Then attach the nsclient.log file here so we can view it for any errors.

The files looks like : RR08A00C.tif and RR08A00A.tif.dat

I am seeing a lot of these errors on the log file.
Failed to parse host nagios-debian: resolve: No such host is known
Failed to query performance counters:


But no details on why the check_files command is failing.
My suggestion id to remove the NSClient Agent and delete the folders and reinstall.
If that fails, remove the client again and install the latest stable 4.x.x version.
There could be bugs in the newer version so lets rule that out.

Ok today I've installed NSclient++ 0.4.4 but same issue.
Then I have upgraded the Nsclient on 0.5.0.64 (instead of 0.5.0.43). Same issue too.

You can find the content of nsclient.log after I have launched the command /usr/local/nagios/libexec/check_nrpe -H xxx.xxx.xxx.xxx on my nagios server.

What's the mean of this sentence : Failed to parse host nagios-debian: resolve: No such host is known ?

Re: Check number of files on a directory

That error is telling you that the windows server cannot file the IP address for the nagios-debian setting in the nsclient.ini file.
Code: Select all
allowed hosts = nagios-debian


Instead of using the hostname, replace it with the IP address of the nagios server and restart the NSClient++ service and that should fix that error.

Try running the command but select a different folder and to see if it works or fails the same.
Code: Select all
/usr/local/nagios/libexec/check_nrpe -H 10.20.2.12 -c check_files -a path='C:\\Windows'
