I'm not a SQL guru, so I would really appreciate the help of the community on this one.
I have all of my nodes assigned to a Region and my manager wants to see a report showing the average availability of each node in a Region over the last 7 days, AND a single average availability value for each Region over the same period. What would the SQL look like for that?
One other question. That same manager prefers to see charts rather than tables. Is is possible to display a chart showing the single average availability for a node or for a Region as a bar chart rather than a table?
Thank you very much for your help.
