check_snmp has wealth of options, including a timeout option. You can explore them by taking a look at the output from "check_snmp -help."

The B machine is the client machine that I need to monitor. In the client machine, i have a script that calculate the number of files on a specific directory ( the output of the script is a number). The path of this script has been added to the snmpd configuration file ( etc/snmp/snmpd.conf) on the client machine and generated an OID for this script. what happens is that every 5 minutes, this script is requested remotly by centreon machine via snmp with this command launched each 5 minutes from Centreon machine : /usr/lib/nagios/plugins/check_snmp -H client_IP_Adress -C All -P 2c -o .1.3.6.1.4.1.8072.1.3.2.3.1.2.22.99.104.101.99.107.95.98.108.111.99.107.101.100.95.102.105.108.101.115.95.112.112 -w 1 -c 2 where -w is for warning if 1 files found and -c for critical if 2 or mores files are found This has been working really fine until now. The problem is that the script that counts the files takes sometimes more than 5 seconds because there is a lot of files to count, and what happens is that if the script doesn't give a result within 5 seconds, the command above get a timeout error. I don't know where to change the timeout, so what i did is modifying the script that counts files, this modifications intend to stop the the command that counts files (inside the script) if it takes more than 4 seconds This is the previous version : #!/bin/bash if [[ "$1" = "PROD" ]]; then received="/mnt/sftpdata/vpod/repository/received/PROD" else received="/mnt/sftpdata/vpodpp/repository/received/PRE" fi echo $(find $received \( -path /mnt/sftpdata/vpod/repository/received/$1/FHU2/v1app2omniaboprd \) -prune -o -type f -mmin +45 -print 2>&1 | wc -l) And this the modified new version : #! /bin/bash if [[ "$1" = "PROD" ]]; then received="/mnt/sftpdata/vpod/repository/received/PROD" else received="/mnt/sftpdata/vpodpp/repository/received/PRE" fi f=$(timeout 4 bash -c "find $received \( -path /mnt/sftpdata/vpod/repository/received/$1/FHU2/v1app2omniaboprd \) -prune -o -type f -mmin +45 -print 2>&1 | wc -l") if [[ "${#f}" -eq 0 ]] then echo '3' else echo $f fi With the new version, normaly when i execute the check snmp command from centreon machine (/usr/lib/nagios/plugins/check_snmp -H client_IP_Adress -C All -P 2c -o .1.3.6.1.4.1.8072.1.3.2.3.1.2.22.99.104.101.99.107.95.98.108.111.99.107.101.100.95.102.105.108.101.115.95.112.112 -w 1 -c 2), i should have the number 3 as a resulat from the external script if the find doesn't answer within 4 seconds, but this is not the case, instead of having 3, i have this message : external command error timeout. and the snmp deamon is killed automaticaly oh the client machine ( inactive (dead)).
