Annotation Improvements

Phoenix v9.0.0 release brings major updates to annotation support, and a whole host of other improvements.

Annotations ๐Ÿท๏ธ

Up until now, Phoenix has only supported one annotation of a given type on each trace. Weโ€™ve now unlocked that limit, allowing you to capture multiple values of an annotation label on each span.In addition, weโ€™ve added:
  • API support for annotations - create, query, and update annotations through the REST API
  • Additional support for code evaluations as annotations
  • Support for arbitrary metadata on annotations
  • Annotation configurations to structure your annotations within and across projects

Annotation Configs

Data Retention ๐Ÿ’ฟ

Now you can create custom global and per-project data retention polices to remove traces after a certain window of time, or based on number of traces. Additionally, you can now view your disk usage in the Settings page of Phoenix.

Hotkeys ๐Ÿ”ฅ

Weโ€™ve added hotkeys to Phoenix!You can now use j and k to quickly page through your traces, and e and n to add annotations and notes - you never have to lift your hands off the keyboard again!
