Problem with script.

[jmasquelet]

Hi, i've Nagios 3 and i'm tryin to put a script in a host.

Script run OK on sh, ksh, bash but when running from Nagios server always return OK.

nagios@sdd11:/usr/lib/nagios/plugins> ./check_nrpe -H sd1 -c check_informix
ok
nagios@sdd11:/usr/lib/nagios/plugins> ./check_informix.sh
NOOO



#!/bin/sh
estado="$(/opt/mw/bin/ifxcheck tarcred sdd narplus meta4)"
tarcred=$(echo $estado | cut -d" " -f1)

if [[ "$tarcred" -ge 30 ]];then
alarma=1
fi

if [[ $alarma -eq 1 ]];then
echo "NOOO"
exit 2
else
echo "ok"
exit 0
fi

it execute ifxcheck but it look like it's not passing the arguments (tarcred sdd narplus meta4) how can i do to pass it?

Can you post the nrpe command directive for check_informix?
Also, is "sd1" the localhost, or another remote box?

nagios@sdd11:/usr/lib/nagios/plugins> ./check_nrpe -H sd1 -c check_informix
ok

[jmasquelet]

its localhost.

./check_nrpe -H localhost -c check_informix

Can you add a few echos to the script and then rerun it through nrpe and from the command line? (post the results)

Code: Select all

#!/bin/sh
estado="$(/opt/mw/bin/ifxcheck tarcred sdd narplus meta4)"
echo "$estado"
tarcred=$(echo $estado | cut -d" " -f1)
echo "tarcred"
if [[ "$tarcred" -ge 30 ]];then
alarma=1
fi

if [[ $alarma -eq 1 ]];then
echo "NOOO"
exit 2
else
echo "ok"
exit 0
fi

And then run:

Code: Select all

./check_nrpe -H localhost -c check_informix
./check_informix

[jmasquelet]

result for ./check_informix.sh


nagios@sdd11:/usr/lib/nagios/plugins> ./check_informix.sh
622 72 53 335
622
NOOO

result for ./check_nrpe -H localhost -c check_informix

nagios@sdd11:/usr/lib/nagios/plugins> ./check_nrpe -H localhost -c check_informix


ok

If SELinux is on, does this work with SELinux turned off?

Code: Select all

setenforce 0
./check_nrpe -H localhost -c check_informix

Since there are two blank spaces above your 'ok' in the second example, that means there is no output value for the echoes abris suggested. It looks like when the script is run via NRPE it cannot check "/opt/mw/bin/ifxcheck".

Since the Nagios user can check '/opt/mw/bin/ifxcheck' properly on the command line, that leads me to believe that SELinux is a possible culprit.

If that does not help, could you please post the results of the following commands:

Code: Select all

cat /etc/xinetd.d/nrpe.conf
cat /usr/local/nagios/etc/nrpe.cfg
