Hello Everyone!!

I am new to nagios, i want count files for a particular folder.I searched on net and found plugin check_winfile, which can be used to count number of files.

I am trying to test but i am getting error : CHECK_NRPE: recived 0 bytes from daemon.

for nsclient i am using version 0.4.1.73-x64.

I am attaching nsclient.ini file.please check the configuration file,correct me if am wrong.

Please help me out in fixing the issue.

NSClient has this functionality built into it:

Check the amount of files in a folder (and sub-folders). Generate a warning if more that 500 files exist, critical if more than 1000 files exist.

Code: Select all

Command:
check_nrpe -H 192.168.142.1 -t 30 -c CheckFiles -a path='C:\\NO BACKUP' pattern=*.* 'master-syntax={%total% Files Found}' MaxWarn=500 MaxCrit=1000

Output:
{12347 Files Found}, found files: 12347 > critical|'found files'=12347;500;1000

There are more examples on my site: http://sites.box293.com/nagios/guides/c ... es-folders

I presume 192.168.1.4 is your nagios server?
From the nagios server, can you just check the nrpe version?
With ssl:

Code: Select all

./check_nrpe -H <windows ip>

Without ssl:

Code: Select all

./check_nrpe -H <windows ip> -n

If that does not work, is the port open?

Code: Select all

nmap <windows ip> -p 5666

Finally, is the nsclient service running on the windows server?
Did you restart the nsclient service after making the changes to nsclient.ini?

Hi abrist,
When i do nmap for my windows client i got the following output :
[root@vmNagiosSever libexec]# nmap 192.168.1.150 -p 5666

Starting Nmap 5.51 ( http://nmap.org ) at 2014-10-11 09:56 IST
Nmap scan report for 192.168.1.150

But When i do check_nrpe, i got the following error :
[root@vmNagiosSever libexec]# ./check_nrpe -H 192.168.1.150
CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.

Please help me to fix the issue.

Can you check your windows nsclient.log file for any details about the connection failure?

Can you please restart the NSClient service on your windows box and try again.

You will need a command definition like:

Code: Select all

define command {
       command_name                  		check_nrpe
       command_line                  		$USER1$/check_nrpe -H $HOSTADDRESS$ -t 30 -c $ARG1$ $ARG2$
}

And a service definition like:

Code: Select all

define service {
	host_name			your_host
	service_description		files check
	check_command			check_nrpe!CheckFiles!-a path='C:\\TEST' pattern=*.* 'master-syntax={%total% Files Found}' MaxCrit=3000
	max_check_attempts		5
	check_interval			5
	retry_interval			1
	check_period			24x7
	notification_interval		60
	notification_period		24x7
	register			1
	}

Hi Box293,

I did the same thing but i am getting error, saying " missing arguments"

But when i am trying from nagios server through terminal, i am getting the following output [screen shot attached and configuration files attached]:

Command :
./check_nrpe -H 192.168.1.12 -t 30 -c CheckFiles -a path='C:\Program Files\NSClient++\' pattern=*.* 'syntax={%total% Files Found}' MaxCrit=80

Output :
"{79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, {79 Files Found}, "

Any solution to this??

Why i am not able to get the value in nagios?? in wepage its showing "Missing argument"

Here is my Command.cfg ::
"define command{
command_name check_nrpe
command_line /usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}

define command {
command_name check_nrpe_files
command_line /usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -t 30 -c $ARG1$ $ARG2$
}"

Defination configuration ::
"define service {

use generic-service,srv-pnp
host_name winserver
service_description Files Check
check_command check_nrpe!CheckFiles! -a path='C:\Program Files\NSClient++\' pattern=*.* 'master-syntax={%total% Files Found}' MaxWarn=500 MaxCrit=3000
}
"

Any fix to this error ??

Hi abrist,

Please help me in configuring check_winfile.

Posted: **Mon Oct 20, 2014 11:37 am**

Use master-syntax instead of syntax
Also, use double back slashes for the folder path

Code: Select all

Command:
./check_nrpe -H 192.168.207.1 -t 30 -c CheckFiles -a path='C:\\Program Files\\NSClient++\\' pattern=*.* 'master-syntax={%total% Files Found}' MaxCrit=80

Output:
{111 Files Found}|'count'=111;0;80
