Nagios Support Forum

Good Morning:

I have the following script:

[root@nagios02 libexec]# cat check_count_file.sh
#!/bin/sh

el_directo=$1
el_warning=$2
el_critical=$3

LS="/bin/ls"
CUT="/usr/bin/cut"
WC="/usr/bin/wc"
GREP="/bin/grep"
FIND="/usr/bin/find"

STATE_OK=0
STATE_WARNING=1
STATE_CRITICAL=2
cantidad=0

cantidad=`$FIND $el_directo |$WC -l`
#cantidad=`$LS $el_directo |$WC -l`

dirsize=`echo $cantidad`
resultado="OK"
exitstatus=$STATE_OK

if [ "$el_warning" != "" ]; then
if [ $cantidad -ge $el_warning ]; then
resultado="WARNING"
exitstatus=$STATE_WARNING
fi
fi

if [ "$el_critical" != "" ]; then
if [ $cantidad -ge $el_critical ]; then
resultado="CRITICAL"
exitstatus=$STATE_CRITICAL
fi
fi

resultado="$resultado - Hay $cantidad archivos en la carpeta $el_directo | 'cantidad'=${dirsize};${el_warning};${el_critical}"
exitstatus=$STATE_OK

echo "$resultado"
exit $exitstatus
[root@nagios02 libexec]#

If I execute the script directly I get the following result:

[root@nagios02 libexec]# ./check_count_file.sh /tmp 2500 3000
OK - Hay 1374 archivos en la carpeta /tmp | 'cantidad'=1374;2500;3000
[root@nagios02 libexec]#


You will notice that it shows the folder, in this case, / tmp and the number of files, 1374, is according to the number of files in that folder.

But if I execute it with the NRPE it gives me other values:

[root@nagios02 libexec]# /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1 -t 30 -c check_count_file /tmp 2500 3000
OK - Hay 584963 archivos en la carpeta | 'cantidad'=584963;;
[root@nagios02 libexec]#

It does not show me the folder and the amount of files is not correct. This is how it is configured in the nrpe.cfg:

command[check_count_file]=/usr/local/nagios/libexec/check_count_file.sh $ARG1$ $ARG2$ $ARG3$

Could you help me? I do not understand why this happens.

Best regards...

[root@nagios02 libexec]# ./check_count_file.sh /tmp 2500 3000
OK - Hay 1374 archivos en la carpeta /tmp | 'cantidad'=1374;2500;3000

You are running your command as root user... NRPE is run as 'nagios' user. Is the number of files the same when you run your command as nagios user?

Even with the user nagios gives me the same result.

[root@nagios02 libexec]# su nagios
[nagios@nagios02 libexec]$ whoami
nagios
[nagios@nagios02 libexec]$

[nagios@nagios02 libexec]$ /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1 -t 30 -c check_count_file /tmp 2500 3000
OK - Hay 580117 archivos en la carpeta | 'cantidad'=580117;;

[nagios@nagios02 libexec]$ ./check_count_file.sh /tmp 2500 3000
OK - Hay 1507 archivos en la carpeta /tmp | 'cantidad'=1507;2500;3000
[nagios@nagios02 libexec]$

Well, you are not passing the arguments... You pass arguments by '-a'.

Example: Try:

Ready, with that argument, -a, it works as it should be.

Thank you very much, you can now block this post.

I am glad I could help!
