Exception Detector
Exception Detector
Overview
This filter plugin consumes a log stream of JSON objects which contain single-line log messages. If a consecutive sequence of log messages form an exception stack trace, they forwarded as a single, combined JSON object. Otherwise, the input log data is forwarded as is. More info at https://github.com/GoogleCloudPlatform/fluent-plugin-detect-exceptions
Note: As Tag management is not supported yet, this Plugin is mutually exclusive with Tag normaliser
