How do I get the availability of a group as a whole in a report?

Question

We have a department that wants the monthly availability of each of their servers that have a specific custom property, and then the overall monthly availability of the whole group of servers with that property.  I tried grouping them in Orion, but the report that report writer creates gives each individual server as expected, and then the availability of the group as 100% instead no matter what the server's availability is.

How do I get the group's availability to reflect the overall group?

what group properties have you set?

If you set the the status rollup mode to the best or "mixed status shows warning" then it'll read 100% unless all of the entries are down.

whereas if you set it to 'worst' status then it will show the [worst] availability of the group.

if you're expecting the average availability of the members of the group then you'll have to average the individual member availability.
