I have tried to setup a "used space reporting" on different klient that we monitor.
then we can show the trend for customer of how much diskspace they are using and growing each month. BUT also telling us as a service provider when to start to look for more disk storage and inform customer about the expansion.
I am using the WMI Multi disk sensor that also includes a "Total" with the id of "-1"
Then i am trying to use the Sensor factory to calculate the "used space" of a server. this is easy on a server with one disk to get the wmi of the logicaldisk size minus the free space.
But it is not possible to use the id "-1" in sensor factory.
It seems also very manaully task for each server and wondering if there is a way to do this a clever way. all the details are in the system it is just a matter of showing the details.
Let me know if others have same problem or in same situation to generate a storage report.
