After Logstash aggregated multiple logs, a tag will be added, while filebeat will not. This will affect my analysis of data and why filebeat does not add a tag？

We considered this feature a while ago:

> <https://github.com/elastic/beats/issues/957>

even had a pull request with the required changes:

> <https://github.com/elastic/beats/pull/2279>

But at some point it was dropped. I suggest you add a comment in the issue, and also reference the PR (#2279)
