Need Plugin Recommendation For Monitoring Shared Folder

Greetings,
I have attempted to locate a plugin to do this, but have not yet found what I'm looking for in the Nagios Exchange. I need a recommendation on what plugin I should use to monitor a password-protected inter-network shared directory, and notify me when the credentials expire (approx every 60 days).
DETAILED SCENARIO:
Users upload scanned documents to our website. The files are placed temporarily in a folder that is being watched by one of our servers and, when a file arrives, our server copies the file to another folder where it gets imported into an archive, that can be viewed by the users online, etc.
The problem is that the folder is password protected and the password expires every 60 days. Once this happens, users start calling customer service, complaining that they can't view their documents on our site. Customer service notifies me. I then notify the website developer, who then resets the password. This whole process usually equates to several hours and can cause up to a hundred phone calls in one day.
I have asked the developer to make it never expire (since we are the only ones accessing it), but he said he tried and can't do it because the share was created on a small business server or some such.
REQUEST:
So, rather than waiting for 100+ users to call us every couple of months, or even have a reminder timer for myself, I would like to set it up so Nagios is actively checking and authenticating the credentials against this network share and, as soon as the share is not accessible, send a notification directly to the website developer (along with a copy to me).
Thanks in advance. This is a great forum.

Just to make sure - you would be creating one service check for each user right?
You would need to create a custom powershell script that checks if the password is expired for that specific user.
Here's a reference that should help -

You can then use a service check with NSClient++ to run that remote powershell script and report back to your Nagios.

Thanks for the reply.
There is only one user that needs to authenticate, and that's our server. The password never changes, it just expires. It is then reset to the same password again once we tell the developer it's no longer working.

The share is not on our domain, so the first one is out, since it is for a domain account. But, the first one might work. I'm checking it out now and will let you know how it goes.
Thanks.

Sounds good, let us know the result once you have a chance to check it out.

Okay, I got a positive result from the command line for the second one (check_smb_share_AA), so that's great.
Now I have to figure out exactly what files to make changes to and what to type in them, lol.
Perhaps, since this is a much simpler plugin than say, "check_printer", this will be a good one to learn how to manage plugins with. I could really use some help getting from this point, to the finish line, if you don't mind.
Also, this isn't something that would show up in my dashboard, right? So, I'll need to just have it set up for email notification.

What is the full command you are using to check with that is returning the proper result for you? Can you post both the full input / output for us to take a look at?

Absolutely.
First, I checked the help for the plugin:
[root@nagioscore libexec]# ./check_smb_share_AA --help
check_smb_share_AA v1.1 (nagios-plugins 2.1.1)

Nagios plugin to check Windows share
Usage:
check_smb_share_AA -H <host> -U USER%PASSWORD -S SHARE
check_smb_share_AA --help
check_smb_share_AA --version
Here is what I ran and the result:
./check_smb_share_AA -H 66.XXX.XX.XX -U username%password -S sharefolder
OK Share : sharefolder

Navigate to the directory where the config files are stored -
At the bottom of the file
commands.cfg, add the following lines -
(this part does not need to be modified.)
Code: Select all
# 'check_smb_share_AA' command definition
define command{
command_name check_smb_share_AA
command_line $USER1$/check_smb_share_AA -H $HOSTADDRESS$ -U $ARG1$ -S $ARG2$
}
From there, navigate to the folder where your host / service configuration files are stored -
Open a new file with the name '<host>.cfg' and add the following lines. Modify to your needs.
Code: Select all
define host {
use linux-server
host_name <host>
alias <host alias>
address <ip address of server>
max_check_attempts 5
check_period 24x7
notification_interval 30
notification_period 24x7
}
define service {
use generic-service
host_name <host> (must be the same as the one entered above)
service_description <decription of service>
check_command check_smb_share_AA!username%password!<share folder>
}
Notice that username%password is defined as $ARG1$, <share folder> corresponds to $ARG2$. You can add more $ARG#$ values if needed for a certain scripts.
Restart Nagios -
Now navigate to your 'Services' page and the check should be functioning properly.
Has this helped you setup a check?
