Hello Nagios forums,

I am trying to implement a pretty simple check to see if a file exists with the name "test-***" where *** will be any random numbers and/or letters. I have tried several combos in Nagios including:

checkfilesize -a D:/downloads/test1/test-% --nodatamode -c _ItemCount=1:
checkfilesize -a D:/downloads/test1/test-%%% --nodatamode -c _ItemCount=1:
checkfilesize -a D:/downloads/test1/test-$% --nodatamode -c _ItemCount=1:
checkfilesize -a D:/downloads/test1/test-$%%% --nodatamode -c _ItemCount=1:
checkfilesize -a D:/downloads/test1/test-$* --nodatamode -c _ItemCount=1:
checkfilesize -a D:/downloads/test1/test-$*** --nodatamode -c _ItemCount=1:
checkfilesize -a D:/downloads/test1/test-* --nodatamode -c _ItemCount=1:
checkfilesize -a D:/downloads/test1/test-*** --nodatamode -c _ItemCount=1:

but none will match the file named "test-123". Obviously if I hardcode the numbers into the check, it works as intended, but these numbers will constantly be changing. Does anyone know how I can use a wildcard in the filepath for this check?

Thank you

Can you post a link to this plugin? Or if it is short/custom, post here in code wraps?

If you are using NSClient++ you can use the build in module CheckDisk/CheckFiles which can do exactly that.

Here is an example.
The following file exists: "C:\Downloads\test1\test-123.txt" AND it has some text added to it (so it doesn't have a byte size of 0).
These commands find any files that start with test-

Using NSClient++ 0.3.9:

Code: Select all

Command:
./check_nrpe -H win2008r2-01 -t 30 -c CheckFiles -a path='C:\\Downloads\\test1' pattern='test-*' 'filter=size gt 0b' max-dir-depth=0 MinCrit=0

Output:
test-123.txt|'found files'=1;0;0

Using NSClient++ 0.4.1.105:

Code: Select all

Command:
./check_nrpe -H win2008r2-01 -t 30 -c CheckFiles -a path='C:\\Downloads\\test1' pattern='test-*' max-dir-depth=0 MinCrit=0

Output:
test-123.txt|'found files'=1;0;0

The plugin I am using is check_wmi_plus.pl:

http://edcint.co.nz/checkwmiplus/?q=faq ... mmandlines

And here's a readme:

http://mastermonsvr.smartmon.com.au/mp- ... mi_plus.pl

I also submitted a query to the check_wmi_plus developers asking about this issue in case they've got a solution. Thanks in advance for the responses

I don't see "wildcards" anywhere in the "checkfilesize" section for that readme, but I do see it for other checks. My guess is it is not implemented.

I received a reply from the checkwmiplus developer:

It can be done but it can timeout the plugin so I did not include it.
Try this

add -d -z to the command line (without any wildcards) Look near the top of the output for the wmic command used "QUERY:"
Run the wmic command from the command line to make sure it works

Modify the wmic query using "like" and "%"
eg
name like "c:\\temp\\PC_task_manager%"'

Try that, see if it works for you

I figured out a different check to use that works, but I've posted this response here for anyone else who may be interested. Feel free to mark this as solved.

Thanks for the help
