Nagios Support Forum

Hi All
We are running Nagios XI 5.2.3 on CentOS release 6.7 (Final)
I'm trying to use "folder_watch.pl" configure over the wizard.
But even on the cl it is not working as you can see below.
I am checking the folder /tmp/nagiosxitest on a remote server over ssh, if the file 'murat.log' is present.
Nagios lists the file, but gives as output "OK - 0 murat.log files found | 'murat.log'=0".
My goal is to trigger an alarm if the file "murat.log" is found in the folder "/tmp/nagiosxitest."
Please help.

You can try using the negate plugin changing the "OK" status to "CRITICAL". For more information on the negate plugin, see the document below:

https://assets.nagios.com/downloads/nag ... ios-XI.pdf

Is the problem not that the plugin does not find the file?
The output show "OK - 0 murat.log files found | 'murat.log'=0".
But as you can see on the"ls -l", there is a file named "murat.log"

Run the following commands and show us the output:

On the remote box: On the Nagios XI server:

Try adding a warning threshold like below to your command. This will make the check return OK if the file doesn't exist and critical if it does.

It's still not working:

[nagios@cnaxi212 ~]$ /usr/local/nagios/libexec/folder_watch.pl -C 'ssh [email protected] ls -l /tmp/nagiosxitest' -F 'murat.log' -T 'files' -w '@1:1'
OK - 0 murat.log files found

The file is there!
remoteserver:/tmp/nagiosxitest # ls -l
total 4
-rw-r--r-- 1 nagios nagios 84 Apr 6 09:57 murat.log

Run the command adding verbose output "-v" and post the output.

[nagios@cnaxi212 ~]$ /usr/local/nagios/libexec/folder_watch.pl -C 'ssh nagios@csvdb008 ls -l /tmp/nagiosxitest' -F 'murat.log' -T 'files' -w '@1:1' -v

Can you zip up the "/usr/local/nagios/libexec/folder_watch.pl" file, and upload it to the forum? I would like to compare it to the one we are using in house.
