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 m=
achine, i have a script that calculate the number of files on a specific di=
rectory ( the output of the script is a number). The path of this script ha=
s 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 c=
entreon machine via snmp with this command launched each 5 minutes from Ce=
ntreon 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 more=
s 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 gi=
ve 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 sc=
ript that counts files, this modifications intend to stop the the command t=
hat counts files (inside the script) if it takes more than 4 seconds
This is the previous version :
#!/bin/bash
if [[ "$1" =3D "PROD" ]]; then
received=3D"/mnt/sftpdata/vpod/repository/received/PROD"
else
received=3D"/mnt/sftpdata/vpodpp/repository/received/PRE"
fi
echo $(find $received \( -path /mnt/sftpdata/vpod/repository/received/$1/FH=
U2/v1app2omniaboprd \) -prune -o -type f -mmin +45 -print 2>&1 | wc -l)
And this the modified new version :
#! /bin/bash
if [[ "$1" =3D "PROD" ]]; then
received=3D"/mnt/sftpdata/vpod/repository/received/PROD"
else
received=3D"/mnt/sftpdata/vpodpp/repository/received/PRE"
fi
f=3D$(timeout 4 bash -c "find $received \( -path /mnt/sftpdata/vpod/reposit=
ory/received/$1/FHU2/v1app2omniaboprd \) -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 ce=
ntreon machine (/usr/lib/nagios/plugins/check_snmp -H client_IP_Adress -C A=
ll -P 2c -o .1.3.6.1.4.1.8072.1.3.2.3.1.2.22.99.104.101.99.107.95.98.108.11=
1.99.107.101.100.95.102.105.108.101.115.95.112.112 -w 1 -c 2), i should hav=
e the number 3 as a resulat from the external script if the find doesn't an=
swer within 4 seconds, but this is not the case, instead of having 3, i hav=
e this message : external command error timeout. and the snmp deamon is kil=
led automaticaly oh the client machine ( inactive (dead)).
Can you please help me with this issue, im really blocked :/
