How to count string occurrence in string? set_field(source_length, length); Is this scenario feasible in pipeline rule? In this article, we will talk about log file parsing process in Graylog and give examples of parsers in several different languages, as well as compare Graylog with Splunk in terms of parsing. This causes the message to be evaluated on the pipelines connected to that stream, unless the stream has already been processed for this message.
