Push log PushLogRecord

Last Updated：2025-11-14

Description

Support bulk pushing of log records to the BLS platform. The log record format can be either TEXT or JSON. For TEXT log records, logs remain unprocessed; for JSON log records, JSON fields are automatically identified (only first-level fields are currently supported, nested fields are not yet supported).

To upload both processed specific fields and raw log text, use the JSON format with the raw log text included in JSON (@raw as the key and raw log text as the value). When processing @raw, BLS will treat its content as the raw log text.
