Sorry about the slow reply.
I dug through some old notes and I found a picture of one of the graphs we used to be able to do. Basically the report was a graphical view of what the host storage capacity is. We then used the information to give to the boss to say this is what our storage is doing we need to purchase more disk (Trending over time).
The problem with VMWare is the SAN knows how much storage has been alocated to the virtual enviroment and how much it has free within the san but not how much the Virtual enviroment is actualy using.
The virtual enviroment knows how much storage has been alocated to VM's but doesnt know how much storage that has been alocated to a VM is actualy used.
Finally you can look at what is used on the VM but that will only tell you how much is used/free at that particular point in time and as you have sujested if you had multiple reports you could see the trend over time and make decisions based on that.
We need to be able to be able to get trending on the actual guest disks in order to plan and to proactivly adjust disk size (we do not use thin provisioning).
Below is a screenshot of the graph we used to be able to get from a previous vendor, this graph actualy uses a percentage which isnt so usefull sometimes because %10 of 600GB is very different from %10 of 20GB the scale needs to show both real and percentage values. Also if it has the hover to get the values the same as you have done with all of your other graphs that would be brilliant.
