Documentation

The script usually is called with the desired file specification and the expected size :

C:> check_filesystem_e.exe subdir=<Programm Dir to scan> filename=<Name of File(s) to scan> filesize=<expected size in bytes>

For debugging purposes, it may also be called with a more detailed output option (this mode is not suitable for continuous operation, but for testing purposes only).

Afterwards it will output the detailed status of the individual components :

C:> check_filesystem_e.exe subdir=d:\logs filename=*.log filesize=7 debug

check_filesystem_e.exe subdir=c:\temp filename=*.log filesize=7 debug
Subdir: c:\temp
Filename:*.log
Filesize:7
c:\temp
        OK: test1.log
        OK: test2.log
        OK: test3.log
        CORRUPT: test4.log
c:\temp\test1
c:\temp\test2
c:\temp\test3
CRITICAL: 4 files scanned in c:/temp - 1 file(s) corrupt - c:/temp/test4.log

For informations and usage you can call it with the help command:

C:\>check_filesystem_e.exe help

Installation

Preferably the plugin is copied into the script directory where you will store your checks under Windows

When using NSClient ++ use an entry in NSC.INI similar to this, pointing to check_filesystem_e.exe:

...
[/modules]
NRPEServer=enabled
CheckExternalScripts=enabled

[/settings/NRPE/server] 
allow arguments=true  

[/settings/external scripts/scripts] 
check_dv_adrarc=scripts\check_filesystem_e.exe subdir=d:\david\archive\address 
filename=*.dat filesize=430 timeout=300
...

Examples

Checks a Tobit David Address-Archive for defects or corruptions on system-files, here: things are OK:

c:\scripts\check_filesystem_e.exe subdir=d:\david\archive\address filename=*.dat filesize=430 timeout=300

OK: 26 Files scanned in d:/david/archive/address: None of corrupt files
