Qradar - how to monitor windows server disk space?

Hello Qradar gurus!  Really need your help on this one. And before you respond --> I know there are many drive-space monitoring solutions out there! I want to utilize a system that I already own to monitor drive space and not introduce ...'yet another utility or process'.

Can someone tell me how to configure Qradar to monitor available hard drive space on a Windows 2003 Server?  

I know that the Windows Server System Event Log generates an event ID of 2013 when a disk is at or near capacity. Any way to use Qradar to look for that event and generate an email alert?

Hi,

Is the windows event in sufficient time? That is, if memory serves me correctly, when there really is almost no available disk left. Wouldn't you want an alert for 20% free space or 10% free space?

I have a powershell script that stores these values in a SQL database, and I query that database each morning as part of my daily checks.

Hi David, What values are you pulling from Windows server?  Are you pulling the info using WMI and piping it into a dbase?

Hi,

Yes I'm using WMI

There are a couple of servers that WMI isn't responding on, so I filter them out of my list.

foreach( $s in Invoke-Sqlcmd -Query ‘select distinct ss.FQDN as ServerName from dbo.SQLServer ss where isWMIWorking = 1 and ( DateDecommissioned is null or DateDecommissioned > dateadd( day, datediff( day, 0, getdate()), 0 ))’ -Database SomeDatabase -ServerInstance SomeServer) {
    $d = Get-WmiObject -computername ( $s.ServerName ) Win32_LogicalDisk -filter "DriveType=3" | foreach { 
        add-member -in $_ -membertype noteproperty UsageDT $((Get-Date).ToString("yyyy-MM-dd HH:mm:ss")) 
        add-member -in $_ -membertype noteproperty SizeGB $([math]::round(($_.Size/1GB),2)) 
        add-member -in $_ -membertype noteproperty UsedGB $([math]::round((($_.Size - $_.FreeSpace ) /1GB ), 2 ))
        add-member -in $_ -membertype noteproperty FreeGB $([math]::round(($_.FreeSpace/1GB),2)) 
        add-member -in $_ -membertype noteproperty PercentUsed $([math]::round(((1 - [float]$_.FreeSpace/[float]$_.Size) * 100),2)) -passThru 
        } | Select UsageDT, SystemName, Caption, VolumeName, SizeGB, UsedGB, FreeGB, PercentUsed | out-DataTable       
    ;

Open in new window
