Non recursive directory monitoring

Hi,
So, we have file age monitoring for a windows directory, but would like to exclude sub-directories. I did some digging, but only found some articles on plugins and not much else. Is this possible with NagiosXI 5.2.9?
Below is the command that we have setup.
Code: Select all
$USER1$/check_nrpe -H $HOSTADDRESS$ -p 5666 -c CheckFiles -a path="d:\\test\\folder\\" pattern=*.csv 'filter=written < -240m' MaxCrit=1 'syntax=%filename%: %write%'

This isn't a limitation for Nagios 5.2.9, it's more of an issue with NSClient++. What version of NSClient++ are you running on your client machine?
If it's 0.3.9, then you'll need to upgrade. If you're using a newer version, then you should be able to follow what @mickem mentioned on a similar GitHub issue.
Code: Select all
Excluding them should be as simple as "filter=creation < -60m and file != '.' and file != '..'" not 100% sure if the syntax of my head, but you can find that in the docs.
See the original GitHub issue here -

Refer to @rkennedy's post. NSClient 0.4.3 or greater is pretty key here.
Here's something I've labbed up:
Documents directory looks like this:
test.txt (written 18 days ago)
sub_directory/sub_file.txt (written 30 minutes ago)
sub_directory/more_sub/more_sub_file.txt (written 2 minutes ago)
This command checks a top-level directory for txt files written less than 1 hour ago:
Code: Select all
[root@localhost libexec]# ./check_nrpe -H 192.168.3.170 -c check_files -a path="C:\\users\\mcapra\\documents\\" pattern=*.txt 'filter=written > -60m' 'max-depth=1'
No files found
This command checks a top-level directory and recurses down 1 level:
Code: Select all
[root@localhost libexec]# ./check_nrpe -H 192.168.3.170 -c check_files -a path="C:\\users\\mcapra\\documents\\" pattern=*.txt 'filter=written > -60m' 'max-depth=2'
OK: All 1 files are ok
This command checks a top-level directory and recurses down 2 levels:
Code: Select all
[root@localhost libexec]# ./check_nrpe -H 192.168.3.170 -c check_files -a path="C:\\users\\mcapra\\documents\\" pattern=*.txt 'filter=written > -60m' 'max-depth=3'
OK: All 2 files are ok
Notice how the 3rd command recognizes more_sub_file.txt and includes it in the count.
You could add parameters such as
'warn=count < 2' 'crit=count < 1' to warn if there are a certain number of files being written in the last hour. Removing the
'max-depth' parameter causes this command to recurse through all sub-directories.

Thanks all.
I will give this a try.

We are currently using 0.39 version of nsclient++. Can we use the old nsc.ini configuration file or do we need to manually configure it?

0.3.9 uses slightly different conventions than 0.4.3 as well as a different file name. Many of the definitions are the same, but you will likely need to review both the old configuration and the new configuration for changes.
