Hi everyone! I’m quite new with APM and I’m only using `db.mysql.query` span type. I’m wondering which are the supported span types as I couldn’t find any list in the documentation. Or is it an arbitrary string? If yes, how they be rendered in Kibana (I’m referring for example about the icon and other details in the UI). Thank you very much! Bye ---

Thanks for asking. This is the current state of the spec all agents conform to: [apm/span\_types.json at master · elastic/apm · GitHub](https://github.com/elastic/apm/blob/master/tests/agents/json-specs/span_types.json) and we currently have a [proposal](https://github.com/elastic/apm/pull/513/files) to modify it a bit. For anything that doesn't fit anything in the spec, you can use `custom`. I hope this helps. ---
