This isn't critical in our environment, and I know there are plenty of higher priority items to be implemented into Orion (such as adding multiple hosts with the same IP ), but it would be great if we could monitor the change in volume usage. This would especially be useful for our Exchange or backup environment. We have spent a lot of time working with alerts to make sure we get alerted to something out of the ordinary as long before users experience any issues as possible, while still eliminating false alarms.
If we could generate an alert that sent us an e-mail if the current usage of a particular volume has increased by several GB over the past few hours regardless of how much actual free space is left could be extremely useful in providing us notice of a possible issue, and maybe early enough that we won't have to call in our admin team late at night.
As always, thank you for your hard work and dedication to making Orion a great product.
I've captured this feature request. It's something we want to do.
