I need help creating a sql statement that will display a simple column chart on node availability. The chart's NPM currently uses make it difficult for management to view total average of availability for high visibility servers. below is an excel chart that upper management said they want the data displayed like this:
the left axis displays percentage the right displays nodes and average availability.
I appreciate any help in this as i really don't want to be exporting availability data and manually creating a chart to send to management daily.
