I noticed that in the 7.16 update ([GitHub PR #6111](https://github.com/elastic/apm-server/pull/6111)), the metricset.period field was marked as dropped because it was unused. However, I still find this field present in later versions, such as 7.17, as described in the [APM exported fields documentation for span metrics](https://www.elastic.co/guide/en/apm/guide/7.17/exported-fields-apm-span-metrics-xpack.html). How can this discrepancy be explained?

Nice catch. I'm afraid the documentation is out of date. `metricset.period` seems to be unused in span metrics in 7.17.

So it is just a kind of field in the log, not the configuration for the apm-server? It can not control the frequency of the event date collection?

That is correct. It is just a field in the resulting aggregated metric document.
