syslog-ng Premium Edition 7.0.34 - Administration Guide

Type:	yes|no
Default:	Use the global trim-large-messages() option, which defaults to no.

Description: Determines what syslog-ng PE does with incoming log messages that are received using the IETF-syslog protocol using the syslog() driver, and are longer than the value of log-msg-size(). Other drivers ignore the trim-large-messages() option.

• If set to no, syslog-ng PE drops the incoming log message.

• If set to yes, syslog-ng PE trims the incoming log message to the size set in log-msg-size(), and adds the trimmed tag to the message. The rest of the message is dropped. You can use the tag to filter on such messages.

  filter f_trimmed {
      tags("trimmed");
  };

  If syslog-ng PE trims a log message, it sends a debug-level log message to its internal() source.

  As a result of trimming, a parser could fail to parse the trimmed message. For example, a trimmed JSON or XML message will not be valid JSON or XML.

Available in syslog-ng PE version 7.0.14 and later.

Uses the value of the global option if not specified.
