Monitor free disk space in Windows 2000

We just implemented SAM 6.0, intergrated with existing NPM 10.6. We have 4 Windows 2000 servers left on our network that I am trying to get SAM to monitor the available disk space. The query I'm using on all the other servers is this:

SELECT PercentFreeSpace from Win32_PerfFormattedData_PerfDisk_LogicalDisk WHERE Name='c:'

Unfortunately, this query generates an "Unexpected error occurred. Invalid Class" message on the Windows 2000 machines. Can this be done through WMI on Windows 2000 or do I have to use something else? If I have to use something else, does anyone have anything already written up? My scripting experience is limited only to Powershell.

Thanks.

Adding the Windows 2000 host as a node managed via WMI in Orion is probably the simplest, most straightforward method for monitoring disk volumes on a Windows 2000 host.

Another option is to enable SNMP on your Windows 2000 machines. Once enabled, add the node to Orion as an SNMP managed node, provide the SNMP community string, and when the resources are listed select the drives you'd like to monitor. Y

Thanks for the help, but unfortunately, I already have the server in NPM and being polled with WMI. The problem is with the query that SAM is running against the server to monitor the disk space. The query looks to be referencing a WMI class that does not exist in Windows 2000. I'm not familiar with the format or commands of the query so I'm having a hard time figuring out how it SHOULD be written. Sorry for not making that more clear in my original post.

Do you have SP4 for Windows 2000 installed? Is all other information available to you via WMI beyond volumes? Have you tried enabling SNMP on that node and managing it that way instead?

If you still want to use custom WMI query to detect free disk space on Win 2000 you could try something like this:

SELECT FreeSpace FROM Win32_LogicalDisk WHERE DeviceID = "C:"

See documentation of Win32_LogicalDisk class for more info. It says "Minimum supported server: Windows Server 2003" but the query seems to work even on Windows 2000 SP4 where I just tried it. Unfortunately this class does not contain field for free space in percents.

However, if this query works for you then monitoring of volume (which can be added also to existing node via "list resources") as aLTeReGo suggests should work as well.

Thanks Petr, that will do. I'll just go into the alert and customize it to trigger and a specific size rather than percent free.
