Hi, In the agent yml file, is there a way to dynamically determine the OS name (windows, Linux, etc) to be included in the log msgs? I'm using filebeats version 7.x. I see this doc for version 6.x using Host fields, but there is no example snippet on how to use it. Also, it seems this may have been removed in 7.x > **[Host fields | Filebeat Reference \[6.8\] | Elastic](https://www.elastic.co/guide/en/beats/filebeat/6.8/exported-fields-host-processor.html)** ---

Yes u can add the host meta data with `add_host_metadata` processor. See [Add Host metadata | Filebeat Reference [7.13] | Elastic](https://www.elastic.co/guide/en/beats/filebeat/current/add-host-metadata.html#add-host-metadata) ---
