I have created a switch performance report for a customer including different metrics like CRC error, Link failre count, sync loss count, signal loss count, encoding in/out errors. But when I compare the report output with the historical graph from web UI. There is a conflict.
Most of above performance metrics showing some values like 4,6,20 and encoding in/out showing values range from -90,000,000 to 800,000,000. When I open same port from webUI and see the history, that shows 0 for all parameters. When we checked the stats on switch, it also show 0 errors. Same thing observed on many switches.
Does ETL process change anything during its process? I tried to set aggregate and roll up function to none. Not worked
