Issue/Introduction
Symptoms: In the "cluster" advanced performance charts (Last day), there is a continuous dip at the right end, observed in the graphs for certain metrics.
Cause
There are some metrics which are Host/Virtual Machine based for cluster entity, the logic uses summation of stats across all Hosts/VMs attached to that cluster. The cluster charts are updated every 15 minutes. On fresh update, the last three 5 minute samples are displayed wrong or are smaller value compared to others.
This behaviour is expected as per design and values will be corrected over period.
Note: In some setups, this dip will not be noticed because, the last 30 minute samples which are skewed will not be displayed at all on the chart.
Resolution
Currently there is no resolution to the issue. This will be fixed in future releases.
