How to tweak the metrics for number of files?

[linearstack]

Hi,

I have a host with which folder path is attached.
I want to tweak that "folder path" that it will send an alert when certain number files in that path exceeds. eg: if number to files exceeds to 100 in that folder it gives an alert.

Folder Watch Wizard

Tried using folder watch but getting the below error while running the command.
Is it a syntax error??
If I'm setting this command for "abc" server which has "abc_data (D:)" drive on it. And Folder it want to monitor is "D:\Test"

error message:
/usr/local/nagios/libexec/folder_watch.pl -D D:\Test -F '[^\0]+' -C 'ls -lA' -r -w 2 -c 4 -f
UNKNOWN ERROR - could not chdir to D:Test - No such file or directory

It seems like you are trying to monitor a Windows host. The "Folder Watch Wizard" is normally used for Linux hosts. You could run it either "locally" or "remotely" (via SSH).

Having said that, there are some 3rd party plugins on the Nagios Exchange that can get the job done for you. Here's a list of search results, using "check files windows":

These are not an official nagios plugins, and not guaranteed to work on all systems, but we will do our best to help you out if you get stuck on something.

Please, review our documentation on managing plugins in Nagios XI here:

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

It will show you how to find and test new plugins, and how to define new commands and services in Nagios XI.

I did installed the required tool as suggested in link previously, but still I'm getting this error message:
"UNKNOWN ERROR - execution of ssh administrator@$HOSTADDRESS$ ls -l C:\Test -R resulted in an error 65280 -"

The link showed up a number of plugins - which one did you install? What is the actual check that you are running?

[linearstack]

"check_files.pl" plugin is installed to get the alerts when threshold for number of files is breached in a folder.

I don't think you could use this plugin on a Windows machine. Try using this one instead:

https://exchange.nagios.org/directory/P ... in/details

1. Download the check_files.vbs and place it in the NSClient++ scripts directory (usually C:\Program Files\NSClient++\scripts).

2. Create a command in the nsclient.ini file under the [/settings/external scripts/scripts] section, for example:

Code: Select all

check_count = cscript.exe //T:30 //NoLogo scripts\check_files.vbs $ARG1$

3. Save, exit and restart the nsclient (nscp) service.

4. Test your command from the command line on the Nagios XI server as such:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H <windows server ip address> -c check_count -a '<arguments>'

Examples:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H x.x.x.x -c check_count -a '-p C:\TEMP -r -w 100 -c 200'
OK: 6 files were matched.|'count'=6

/usr/local/nagios/libexec/check_nrpe -H x.x.x.x -c check_count -a '-p C:\TEMP -r -w 5 -c 10'
WARNING: 6 files were matched.|'count'=6

/usr/local/nagios/libexec/check_nrpe -H x.x.x.x -c check_count -a '-p C:\TEMP -r -w 1 -c 2'
CRITICAL: 6 files were matched.|'count'=6

Here, I am specifying the path to my folder with '-p', and I am using '-r' for "recursive". As you can see, changing the warning and critical thresholds changes the message (output).

Here's the plugin's usage (help):

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H x.x.x.x -c check_count -a '-h'

Hope this helps.

We are using wmi for monitoring and authentication and have not setup NSCA/ NSclient.
Can suggest a wmi plugin to perform this??

Unfortunately WMI cannot run custom plugins
