> > Do you mean only remain three basic metrics(`requests_total`, `requests_duration_seconds`,`bytes_total`), and use label to distinguish different requests? > > Yes. This may cause inaccurate collection of some metrics, especially `HistogramVec`(`Histogram`). Different metrics have different value ranges, but if the share the same bucket, it will affect sampling. For example(not target the metrics in OpenDAL), size range of metrics A is `0~1KB`, and metrics B is `10Mb~100Mb`, not sure in this case whether `exponential bucket` can satisfy. -- This is an automated message from the Apache Git Service.
