How to interpret "Time spent by span type"?

[giovere]

Kibana: 7.8.1
APM-server: 7.8.1
Elasticsearch: 7.8.1
Java agent: 1.19.0

In my "Time spent by spant type" I get following entries:

• app - according to https://www.elastic.co/guide/en/kibana/7.x/transactions.html app represents uninstrumented part of the code
• custom - instrumented code
• http - ?
• oracle - Oracle is obviously time spent in the DB, but is this time spent on DB-host itself?

Can you please tell me what http means in this context?

Can you please tell me what http means in this context?

It means spans related to outgoing HTTP requests

@giovere

oracle - Oracle is obviously time spent in the DB, but is this time spent on DB-host itself?

All data in this view comes from the traced service, meaning - it is based on client data, in this case Oracle DB client queries

Thank you for the clarification.
I still do not quite understand HTTP part, can you please give few examples what it could include?

Apparently HTTP ist the time spent in communication with other services through HTTP.
