How to monitor file size

[Frédéric GRANAT]

Hi,
I would like to monitor the size of a particular file, file located on a windows server.
By example :
If size != 0 : alert

In case of alert, I would like to send it to an email address.

Ideally I wouldn't like to install a component on my server (nrpe client,...etc)

What's the easiest way to perform that ?

We have some plugins on the Exchange that check the file size of files on SMB shares, or FTP servers. Maybe one of these could be useful?

Another option would be to create a passive check. This would be more work without an agent like NCPA on the system. But not impossible. You could create a Powershell script to query WMI for the file size, and report back via NRDP on the Nagios XI server. Here is a document that shows more information about NRDP.

Here is an example Powershell command for getting the size of a file.

Code: Select all

(Get-WmiObject -Class CIM_LogicalFile -Namespace "root\cimv2" -Property "FileSize" -Filter "Name = 'C:\\Monitoring\\ReadHere\\blah.txt'").FileSize
