Monitor a Folder Size in Windows

[lpereira]

Hello all:
I'm wondering if there are a possibility to monitor a specific folder in Nagios XI, (for instance, System Volume Information).

We want to receive an alert once the folder reaches (for example) 8 or 10gb of used space on the disk.

is there a way to configure this?

Thanks in advance.

i have doubts regarding check_folder_size. the script says i need "NRPE_NT daemon". i have installed NSclient ++ on my windows machines instead. it is the same? should i install anything extra?

regards.

I was able to get it work with slight modifications. I saved the check_folder_size.vbs script to c:\program files\nsclient++\scripts\ and then to find the size of the nsclient++ folder I added the following command line to the settings/external scripts/scripts section:

Code: Select all

[/settings/external scripts/scripts]
check_foldersize=C:\windows\System32\cscript.exe //NoLogo //T:30 "c:\program files\nsclient++\scripts\check_folder_size.vbs" "c:\program files\nsclient++\" 50 78

So, i need to specify every Folder i want to monitor on the nsclient.ini file? as you did for Nsclient++ folder?

Or have your NSClient++ command definition for check_foldersize accept an argument that represents the path. Then you would configure the individual folders on the Nagios side of things. Both are viable options.

Which command should i run on the Linux side?

i got an error trying to invoke check_nrpe

[root@NAgiosxi libexec]# ./check_nrpe -H xxx.xxx.xxx.xxx -c check_foldersize
CHECK_NRPE: Error - Could not complete SSL handshake.

Code: Select all

    [/settings/external scripts/scripts]
    check_foldersize=C:\windows\System32\cscript.exe //NoLogo //T:30 "c:\program files\nsclient++\scripts\check_folder_size.vbs" "c:\program files\nsclient++\" 50 78

could be:

Code: Select all

    [/settings/external scripts/scripts]
    check_foldersize=C:\windows\System32\cscript.exe //NoLogo //T:30 "c:\program files\nsclient++\scripts\check_folder_size.vbs" "$ARG1$" 50 78

for example and you could then run:

Code: Select all

./check_nrpe -H NSCLIENTIP -c check_foldersize -a "c:\program files\nsclient++"

For the handshake error, check the nsclient and make sure you have a line that allows the nagios machine to connect. It should look like:

Code: Select all

allowed hosts = 127.0.0.1, nagios_ip_address

If you edit this file you need to restart the nsclient service.

i was able to have it working by adding a "-n" at the end.

[root@NagiosXI libexec]# ./check_nrpe -H 172.30.0.56 -c check_foldersize -n
OK:8,6 MB|'FolderSize'=8.59999MB

Now i would need to figure out how to add it as a service in NagiosXI GUI

this should help explain it - https://assets.nagios.com/downloads/nag ... gement.pdf

basically, navigate to CCM, click 'services', create a new one, assign the host as the host for 172.30.0.56, select the check command as 'check_nrpe' and fill out your argument variables to line up with what you're running over the CLI.
