Elastic Cloud with APM via .NET Classic Agent.  
Goes to the SIEM Source IPs, and see that Bytes In / Bytes Out are Empty

AMP transaction contains request and response length. So I think these fields should be filled.

Hey there Mikhail,

So the `Source IP` & `Destination IP` tables are going to query for `source.bytes` and `destination.bytes` to populate the `Bytes in/out` columns (you can verify this using the inspect feature in the top right of the table). I just checked with the APM folks and it doesn't appear that the APM Agent will populate those fields, so that's why you're seeing `0B` in those columns.

I believe the behavior here should be that `Bytes in/out` should show `--` to indicate that there is no data, as opposed to displaying `0B`. I've open [this issue](https://github.com/elastic/kibana/issues/66495) to address this.

Thanks for pointing this out Mikhail! 🙂
