Pulling up an interface utilization graph, it defaults to 1 day resolution. Using the graph edit feature changing the resolution to 1 hour, then applying the settings results in the same 1 day resolution when the graph comes back up. Double checking again, the setting are set for hourly, but again the graph is daily.
Over 90 days
Setting up a report in DX NetOps Performance Management using 5 Minute Resolution reverts to the Views default Resolution when run for more than 90 days. The Role the User is assigned does have the "Run Dashboards At Higher Resolution" Role Right assigned.
Running the same report for 90 days or less works fine.
