One thing to keep in mind for trending is to understand
the limitations of linear regression when trending and forecasting data.
I’ve used the graphs below as an example of this.
In the
second graph you can see what will happen eventually when that bottoms out or
someone goes in and allocates more storage or frees more storage up – it skews
the trend line.
Space Capacity – Different Viewpoints
We’ve
talked about different viewpoints when looking at your data, reports, trending
and now I’m going to look at how useful it is to look at things in Groups.
You can
group by Business, Application, Host, Storage Array, Billing
Tier and what that really boils down to is providing more of a business or
application view.
Below you can see this has been grouped to provide a commercial/business
and a technical view. Application owners can go in and see how much storage
they are consuming, particularly useful if you also include billing
information.
Join me
