Disable host.* fields by default for CrowdStrike module (#19132)
Browse files Browse the repository at this point in the history
For the CrowdStrike module when data is forwarded to Filebeat from another host/device you don't want Filebeat to add `host`. So by default this modules add a `forwarded` tag to events. If you configure the module to not include the `forwarded` tag (e.g. `var.tags: [my_tag]`) then Filebeat will add the `host.*` fields.
