Add Capture Expressions #9694

jpbempel · 2025-10-08T08:31:10Z

What Does This Do

Previously watches, capture expressions allow to describe what exactly
we want to capture and put into a snapshot for a log probe.
When one or more capture expressions is defined, only the capture expressions are added to the Captures part of the snapshot. Expressions can be complex using the expression language and must return a value from which we start to capture the object graph following the limits that can be defined per capture expressions. A new attribute captureExpressions is added into the snapshot.

Motivation

implementation of the Capture Expressions RFC

Previously watches, capture expressions allow to describe what exactly we want to capture and put into a snapshot for a log probe. When one or more capture expressions is defined, only the capture expressions are added to the Captures part of the snapshot. Expressions can be complex using the expression language and must return a value from which we start to capture the object graph following the limits that can be defined per capture expressions. A new attribute captureExpressions is added into the snapshot.
