A problem to check QNAP through SSH

Hi, i've made a simple scritp to check if the syslog file on a nas is updated and locally (on the nas) is working.
This is the script:
Code: Select all
#!/bin/bash
z=`ls /share/CACHEDEV1_DATA/Public/messages -l | awk -F'administrators' '{print $2}' | awk '{print $3}' | cut -c 1-4`
y=`date | awk '{print $4}' | cut -c 1-4`
if [ "$z" = "$y" ]
then
echo "Ricezione Syslog Funzionante (z=$z y=$y)"
exit 0
else
echo "Attenzione, controllare funzionamento Syslog. (z=$z y=$y)"
exit 1
fi
locally i got this result:
Code: Select all
Ricezione Syslog Funzionante (z=11:0 y=11:0)
But when i run the check from nagios with the command
Code: Select all
/usr/local/nagios/libexec/check_by_ssh -H xx.xx.xx.18 -C "/nagios/check_syslog.sh" -p 9022 --logname=admin
the result is
Code: Select all
Attenzione, controllare funzionamento Syslog. (z=18 y=11:0)
i always got z=18 and i don't undestand when it came from..
maybe the ip but i don't undestand
any idea?

First, when you ssh into the QNAP yourself, are you logging in as 'admin', just like the check_by_ssh plugin?
Second, I think we'll need to see the output of
Code: Select all
ls /share/CACHEDEV1_DATA/Public/messages -l
Maybe even get a better understanding of how files are populated there.

yes, i log with the user 'admin'.
this is the output from the nas
Code: Select all
[~] # ls /share/CACHEDEV1_DATA/Public/messages -l
-rw-r--r-- 1 admin administrators 3062601 2020-09-21 09:05 /share/CACHEDEV1_DATA/Public/messages
and this is from nagios
Code: Select all
[nagios@nagiosprod root]$ /usr/local/nagios/libexec/check_by_ssh -H x.x.x.18 -C "ls /share/CACHEDEV1_DATA/Public/messages -l" -p 9022 --logname=admin
-rw-r--r-- 1 admin administrators 3062601 Sep 21 09:05 /share/CACHEDEV1_DATA/Public/messages
that's interesting..like the nas seems to have deleted my script..ok i think i'll change the approach and make the check on the nagios side analyzing the result of the remote ls command..
