-- `traces` discards only the traces that match the `ignored_patterns`. No metric events are ignored.

-`unmatched` properties are:
-- `unset` leaves the `http.route` property as unset.
-- `path` copies the `http.route` field property to the path value.
-  - Caution: This option could lead to a cardinality explosion on the ingester side.
-- `wildcard` sets the `http.route` field property to a generic asterisk-based `/**` value.
-- `heuristic` automatically derives the `http.route` field property from the path value based on the following rules:
-  - Any path components that have numbers or characters outside of the ASCII alphabet (or `-` and _), are replaced by an asterisk `*`.
-  - Any alphabetical components that don’t look like words are replaced by an asterisk `*`.

-You must specify the `output` block, but all its arguments are optional.
-By default, telemetry data is dropped.
-Configure the `traces` argument to send traces data to other components.
+`patterns` and `ignore_patterns` are a list of patterns which a URL path with specific tags which allow for grouping path segments (or ignored them).

+- `heuristic` automatically derives the `http.route` field property from the path value based on the following rules:
+  - Any path components that have numbers or characters outside of the ASCII alphabet (or `-` and _), are replaced by an asterisk `*`.
+  - Any alphabetical components that don’t look like words are replaced by an asterisk `*`.
+- `path` copies the `http.route` field property to the path value.
+  - Caution: This option could lead to a cardinality explosion on the ingester side.
+- `unset` leaves the `http.route` property as unset.
+- `wildcard` sets the `http.route` field property to a generic asterisk-based `/**` value.
