I have come across lot of articles on data sampling in azure application insights. But not able to understand the actual meaning . As per my current understanding it 0% data sampling indicates azure application insight will not do any sampling and retain all the telemetric data logs to application insight logs.

Is my understanding correct?

CodePudding user response：

It's the opposite from your understanding:

100% sampling means that all ingested data will be retained.

0% sampling: No data is retained at all.
