We have Opscenter Enterprise Edition 3.1.1 (agent 3.1.1) running in a Development environment (OS: RHEL 6.4) . On certain graph in the Opscenter, it explicitly show "NO DATA" on the graph in the weekly view. When I zoom in to the hourly view, it shows graph in the same interval where it say "NO DATA" in the weekly view.
Why would this data missing from weekly view but not hourly view? Can anyone explain that?
We are also running NTP across all the cassandra nodes.
