Dear team,
I have two machines A and B, the A is snmp manager with centreon installed on
it.
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)).
Can you please help me with this issue, im really blocked :/
