.. _param-mmjsonparse-max_scan_bytes: .. _mmjsonparse.parameter.max_scan_bytes: max_scan_bytes ============== .. index:: single: mmjsonparse; max_scan_bytes single: max_scan_bytes single: scan limit .. summary-start Maximum number of bytes to scan when searching for JSON content in find-json mode. .. summary-end This parameter applies to :doc:`../../configuration/modules/mmjsonparse`. :Name: max_scan_bytes :Scope: action :Type: positive integer :Default: 65536 :Required?: no :Introduced: 8.2506.0 Description ----------- Sets the maximum number of bytes to scan when searching for JSON objects in find-json mode. This prevents performance issues with very large messages by limiting the amount of data that will be examined. When the scan limit is reached without finding a complete JSON object, the message is treated as non-JSON and processed through the fallback path (creating a simple JSON object with the original message as the "msg" field). This parameter is only effective when mode="find-json". Input usage ----------- .. _mmjsonparse.parameter.max_scan_bytes-usage: .. code-block:: rsyslog # Scan up to 32KB for JSON content action(type="mmjsonparse" mode="find-json" max_scan_bytes="32768") # Use default 64KB scan limit action(type="mmjsonparse" mode="find-json") See also -------- See also the :doc:`main mmjsonparse module documentation <../../configuration/modules/mmjsonparse>`.
