Scenario: Created a simple DRV to calculate "Frame loss" per streamblock.
Selected the counter "Frame Loss" under "Stream block" category
But the counter always reports zero, even after there is an actual loss of frames.
Resolution: What had gone wrong here is the DRV configuration.
We are supposed to select “Streamblock” as the object for this measurement, while creating the DRV.
But the selected one was the default object “Port”
Here the “Frame loss” counter is a stream statistic which is predefined under streamblock statistics.
Made a new DRV named “New_traffic” using streamblock as the object & it works fine.
