Monitor Window Mount Point Freespace

Hello All,


 I am using Orion Network Performance Monitor v. 8.5.1 and was wondering if there was a way to monitor free space in windows mount points.  We are using mount points on our SQL clusters to overcome the drive letter limitiation.


 Is it possible to monitor windows mount point freespace with Network Performance Monitor?  If no there a plugin or another Orion product that will?

Powershell also offers a lot when it comes to monitoring more complex assets of an environment. The following script helped us a lot monitoring our mountpoints. Hope it is helpfull!

 So I have seen this question asked a few times, but never an answer.  Does anyone know if this can be done?  Anything in the new ver.9 that might help?

 

Thanks,

Ron

I don’t believe there is a way to monitor mounted volumes over SNMP. From what I can see, the only service that will provide this information is WMI.

The SNMPv2-MIB:host MIB describes drive size under windows, however local mounted drives are not displayed in this MIB.

As per this kb  http://support.microsoft.com/kb/q237295/ Microsoft does not have any other specific MIB/OID to monitor such drives. Do you own ipMonitor?

 Thanks for the info Mark.  Unfortunantly we do not own ipMonitor at this time.  Is there any talk of adding this type of monitor into NPM?

 You'll be able to do this with Orion APM 2.0, which should launch fairly soon.

So, how would this work?  I am running Orion 9.1 and APM 2.0.  I need to monitor Windows drive mount points.  Ideally I would like them to show up list like normal drive letter disks in Orion.  But based on the info in this thread it seems like it can only be done in APM.  How do you set that up?  Will it show up differently than the rest of the disks?

You can use an APM component monitor.  It won't show up the way disks show up in NPM.  It'll show up in APM.

Assuming the Windows server hosting the mapped drives uses quota, you can use the following WMI class:

The Win32_DiskQuotaassociation WMI class tracks disk space usage for NTFS file system volumes. A system administrator (SA) can configure Windows to prevent further disk space use, and log an event when a user exceeds a specified disk space limit. An SA can also log an event when a user exceeds a specified disk space warning level.

 

DiskSpaceUsed

Limit

QuotaVolume

Status (0-Ok 1-Warning 2-Exceeded)

User

WarningLimit

 

Then some WMI Performance Counter Monitors under APM will do the rest.
