easier said than done
If you want the total for all disks there us a Total Guest File System Free (GB)
If you want specific disks there is a Guest File System usage for each disk. you will have to create a supermetric and take that away from the guest file system capacity (GB) that will give you the capacity remaining in GB
The biggest problem is if you have lots of different drive letters. The Guest File System usage for each disk is drive letter specific so if all the drive letters you want are d: then easy but if they are all over the place you will need to create a super metric for all drive letters you want and then create symptoms and alarms based on the super metrics and then enable the alarms through policies.
I dont do this so i dont know if a super metric that has no data will be seen as having a value of 0. If it dies then different policies for each alert will need to be created and applied using custom groups.
There may be an easier way. If so i dont know it. Hopefully someone else here can help if there is.
There is a metric available called Guest File System Free (GB). This metric is disabled by default. I've enabled this in the policy.
This metric will then be available under the disk drives (drive letters) for virtual machines.
Depending on the drives that you have within virtual machines in your environment it will display the available drives.
In my case i have only a C:\ and E:\ and therefore it will only display those.
Based on this metric I've created the symptoms/alert for disk space left based on GB. For example: if E:\ is less than 2GB remaining i want to be triggered with an alert. There is no need to create Super Metrics.
I tested this with version 6.6.1.
Again, thanks for helping me in the right direction.
Crap. You're right, it's there. I suppose I should have looked for that. Thanks for the info.
