Vector has a concept "conditions" that are used to qualify events. For example,
this is used in Vector's unit testing feature,
swimlanes transform, and
filter transform. This change adds new predicates
that enable powerful matching and condition expression. Specifically, the
following predicates were added:
For example, you can filter all messages that contain the
error term with
[transforms.errors]type = "filter"condition."message.cotnain" = "error"
The world is your oyster.
