Reports for SDWan Tunnels automatically change resolution to 30 min if you run them for 2hr or more
Release : 20.2
Component : Virtual Network Assurance For CA Performance Management
This is an intended change in behavior as of PM 20.2.2 to try to reduce report clutter.
Symptom: SDWan Performance and Baseline charts show spikes on trend lines, chart renders with clutter when resolution is under 30 minutes.
Resolution: With SDWan trend charts are forced to use 30 minute resolution when time range is two more hours to eliminate spikes on trend lines that that clutters rendered charts.
