defaultMetadata() function

Parses the default record metadata out of LOGGER_METADATA, expanding %name and %version first.

Signature:

export declare function defaultMetadata(): JsonObject;

Returns:

JsonObject

the parsed metadata, or an empty object when unset

Exceptions

TypeError if the variable is set but not parseable as JSON

Remarks

These fields are attached to every record sent to a transport — a source tag, an environment name, a hostname — and are what makes records from several services distinguishable at the collector. Console output is unaffected.
