How to create Check Folder size

[bostjanc]

Hi there.
I am a rookie in nagios stuff.
So far I have managed to install and configure:
Nagios on Linux CentOS 7
NagiosQL on Linux CentOS 7
NsClient++ 0.4.4.15

I am using integrated commands: (check_nrpe_arg_ssl) for checking free space on disk on Windows server.
$USER1$/check_nrpe -H $HOSTADDRESS$ -p 5888 -u -t 60 -c $ARG1$ -a $ARG2$ $ARG3$ $ARG4$ $ARG5$ $ARG6$ $ARG7$
check_drivesize
'drive=C'
'warn=used gt 80%'
'crit=used gt 90%'

So far so good.

Now the next step is to implement checking folder size on Windows Machines.
I'm tottaly lost here so please a little help.
1st I have tried using "the integrated default stuff":
check_files
path=d:\temp
warn='size gt 1G'
crit='size gt 2G'

And I can see that this checks only file sizes but not folder sizes.
Ok, so my next assumption is that I Will probably need to get a script on the internet for checking folder size, and put it on nsclient++ on Windows machine under scripts.
Here comes the fun part of being a rookie:

1ST QUESTION:
Would it be better that this written as VBS or POWERSHELL script or it really doesn't mater?

2ND QUESTION:
How do you enable the script to work with nsclient++?
Let me explain my question:
So GOOGLE returned me the results for folder size scripts for nagios usage and I found this VBS script which seems ok to me:
https://exchange.nagios.org/directory/P ... bs/details
The idea is that I wish to be alerted when 1 folder exceedes 5 GB of size.


So I have downloaded the VBS and copied it on Windows machine where NSCLIENT++ is installed: C:\Program Files\NSClient++\scripts
Now the next step I assumed you Will probably need to declare that you have a new super-trupper VBS script in the scripts folder so that NsCLient++ Will be aware of it. I assumed that you do that by editing:
C:\Program Files\NSClient++\nsclient.ini
So far everything logical except what to put in nsclient.ini?
On this txt (https://exchange.nagios.org/components/ ... 2&cf_id=29) it's saying that you must put:
set your nrpe.cfg for command for example
command[check_foldersize]=c:\windows\system32\cscript.exe //NoLogo //T:30 c:\nrpe_nt\bin\check_folder_size.vbs c:\yourfolder 50 78
50 70 are parameters for warning and critical value in MB

Logical, but I use Nsclient++ and not NRPE client on Windows machine, so I guess syntax will be different, right?
This is the ini file that I have it on Windows machine:
https://drive.google.com/file/d/0B_Cst0 ... sp=sharing
So what to put in ini for check_folder_size.vbs to work?
Do you configure it like allias?

Please respond

With best regards

1ST QUESTION:

As a not Windows guy, I can't tell you for sure, but I would say whatever you're the most comfortable in.

How do you enable the script to work with nsclient++?

Take a look at this article, it should clear it up for you a bit: http://docs.nsclient.org/howto/external_scripts.html

Please respond

That's our job.

Thank you for the reply.
I have manged to establish vbs script working

I needed to add this lines into ini file:
[/settings/external scripts]
allow arguments=true

[/settings/external scripts/scripts]

; my script
check_folder_size = cscript.exe //T:30 //NoLogo scripts\\check_folder_size.vbs "$ARG1$" "$ARG2$" "$ARG3$"

But now I have one more problem regarding the VBS scripting not working ok.
As soon as put SUBFOLDERS in PATH it does not work.
Working: D:\FOLDER
Not working:
D:\FOLDER\SUBFOLDER
D:\\FOLDER\\SUBFOLDER
"D:\FOLDER\SUBFOLDER"
'D:\FOLDER\SUBFOLDER'

Status information: " C:Program FilesNSClient++scriptscheck_folder_size.vbs(29, 1) Microsoft VBScript runtime error: Path not found "

[bostjanc]

But the funny thing is that running VBS with arguments on client Works with no problem. With " or without it.

I found the solution.
You need also to add to ini for it to work:
[/settings/NRPE/server]
allow nasty characters=true

[/settings/external scripts]
allow nasty characters=true

Awesome! Yes, NSClient++ has some security in play to prevent everything from executing.

Are we good to mark this thread as resolved?

[bostjanc]

Yep, case closed.
With best regards
