how to monitor disk space for mount points

According to this older thread, you need APM (SAM) to monitor mount points using a component monitor:

Hope that helps,

Use WMI and not SNMP. You will then see the mount points.

I realize this is an old post but thought I'd add how I monitor our Exchange mounted volumes so it may help others.  I do use APM (SAM) as cmgurley mentioned above.

This is a from a template containing a "performance counter monitor" that will provide space remaining returned in GB. In the "instance" section list the full path to your mount point.  Make sure to note the other fields data.

Edit: screenshot is horrible once posted so i'll list the field data:

Coponent Type: Performance Counter Monitor

Counter: Free Megabytes

Instance:  <list full file path to mount point here>

Category: LogicalDisk

Convert Value: YES     Custom conversion - FORMULA: KiloToMega(${Statistic})

This is another "performance counter  monitor" that will provide space remaining returned in a percentage. Again, in the "instance" section list the full path to your mount point and note the other field data.  After creating the SAM template apply it to your exchange server.

Edit: screenshot is horrible once posted so i'll list the field data:

Coponent Type: Performance Counter Monitor

Counter: % Free Space

Instance:  <list full file path to mount point here>

Category: LogicalDisk

Convert Value: YES     Custom conversion - FORMULA: Round(${Statistic},1)

Now you can create necessary email alerts and summarize the data using the web part labeled "Top XX Components by Statistic Data"if you choose as I have in the shot below for quick viewing. Hope this helps!

This is how they show up in APM.

I'm currently running SAM 6.0.0.  My mounted volumes are not listed when I do a "list resources" against my mailbox servers.  Are there any other requirements that you know of that I may be missing?  I do not have hardware health monitoring enabled against them as I do not have the IBM systems director agent installed on the server.  I don't think that is a requirement though........could be wrong.

Go into the node management. Switch from SNMP to WMI then list resources.

Thanks!!!  I think I'm going to stick with my current form of monitoring via SNMP and using SAM templates though.  It appears I will lose my current data/trending if I switch to WMI now and monitoring WMI vs SNMP will use five times the resources.  Maybe for future servers with mount points.  Thanks again!

If you have APM, you can monitor the free space on the Volume Mount Points via a Windows Script Monitor with a VBScript.  WE use this and it works great.  Below is the Monitor Description and the VBScript we use and the Script Arguments.  You will have to manually edit the WarningThreshold and CriticalThreshold variable values before running on the nodes.  As long as you know which nodes have Volume Mount Points, you would then assign this SAM Template to those nodes.  You also may want to set up an Advanced Alert.  :

Component Description:  This monitor is required only on nodes with Sub-Directory Mount Points.  We are using the out-of-the-box SolarWinds Volume Monitoring instead for regular root level drive monitoring (e.g. C:\).  Logical Disk Freespace check for Sub-Directory Mount Points (where the DriveLetter IS NULL).  If Statistic has a value of 2 then one or more Sub-Directory Mount Point drives are in Warning status and no Sub-Directory Mount nPoint drives in Critical Status (reports on all Sub-Directory Mount Point drives in Warning status).  If Statistic has a value of 3 then one or more Sub-Directory Mount Point  drives are in Critical status (reports on all Sub-Directory Mount Point drives in both Waring or Critical status).  Reports on all Logical Volumes in WMI Win32_Volume object where the DriveLetter IS NULL (designating it as a Sub-Directory Mount Point) AND the DriveType = 3 (Local Disk)
