Need to Monitor Hard Drive Storage Space with SCOM 2007

Hi

I'm trying to setup Hard Drive Storage Space Monitoring with SCOM 2007. At the moment I've managed to setup some kind of monitoring but I'm running into problems. I've created a procedure and I'll upload it to this post. I setup drive monitoring by creating a simple threshold and I also borrowed some code from the  Logical Disk Free Space monitor from the Windows Server 2003 Operating System Management Pack. I created a number of monitors to monitor a number of difference partitions on my production servers. For example I setup a monitor to monitor 1GB on C: partitions on all production Servers. The problem I'm getting now is duplicate alerts in other words if threshold drops below 1GB that's fine and I get the alert message. However I also getting a couple of other messages stating that the E and F drives has dropped below 1GB! . When I digg further into the alert I see that it's really just another alert for the C: partition!

The disk $Target/Property[Type="Windows!Microsoft.Windows.LogicalDevice"]/DeviceID$ on computer $Target/Host/Property[Type="Windows!Microsoft.Windows.Computer"]/PrincipalName$ is running out of disk space. The values that exceeded the threshold are $Data/Context/Property[@Name='PctFree']$% free space and $Data/Context/Property[@Name='MBFree']$ free Mbytes.

In the screenshot for Step 13 - did you pick a drive or leave the _Total selected?

I wonder if Windows sees the Logical Partition from the controller level?  If you created a Extended partition on the controller then carved it up into multiple logical drives, I wonder if Windows still only deals with this at the partition level?

It's a simple WMI query.  Can you take a look manually using wbemtest to see what is being seen by WMI?

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

Hmm I'm not sure how to use wbemstest! Well I'm monitoring Virtual Machines on an ESX server if that's any help. I'm also running IBM Director agents on these virtual machines that monitor drive storage. IBM director is able to monitor each partition with no problems.......

You can set alerts in ESX.  You can also choose what to do with these alerts - email you or send an SNMP trap.

Send the trap to Director.

Can you send them to SCOM?  I'm only familiar with MOM - haven't had the chance to spool up SCOM yet.

Why don't you use the basic SCOM monitor for disk space monitoring?
You can set % value's and MB value's for system(c:) and non-system drives.
You did a good job creating you own rules but i guess thats why your getting duplicate error now.
Have a look in the authoring pane of the SCOM console and look in the rules and monitors for the Windows 2003 logical disk(scope) space and set the appropriate overrides.

Hi wwwally,

Sorry for the delay reply. That almost fixed the problem and I tested the method on one of my test virtual machines. I did an override on monitor Logical Disk Free Space. I'm getting an warning message on my console but I'm not getting an alert message! The warning message is coming up in health explorer but not in the top pane of the console! I checked the monitor and alerts is enabled by default! I've attached print screens.
