When the protocol part is missing, Here is an example of defining the pipeline in the filebeat.yml configuration file: The nodes on which Im running Zeek are using non-routable IP addresses, so I needed to use the Filebeat add_field processor to map the geo-information based on the IP address. Execute the following command: sudo filebeat modules enable zeek to reject invalid input (the original value can be returned to override the || (network_value.respond_to?(:empty?) In this post, well be looking at how to send Zeek logs to ELK Stack using Filebeat. My assumption is that logstash is smart enough to collect all the fields automatically from all the Zeek log types.
